+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [Unreleased]
+
+## [0.0.3] - 2026-02-02
+
+### Added
+- Polyphonic parameters: param words (`note`, `freq`, `gain`, etc.) and sound words now consume the entire stack, enabling polyphony (e.g., `60 64 67 note sine s .` emits 3 voices).
+- New random distribution words: `exprand` (exponential) and `logrand` (logarithmic).
+- Music theory chord words: `maj`, `m`, `dim`, `aug`, `sus2`, `sus4`, `maj7`, `min7`, `dom7`, `dim7`, `m7b5`, `minmaj7`, `aug7`, `maj6`, `min6`, `dom9`, `maj9`, `min9`, `dom11`, `min11`, `dom13`, `add9`, `add11`, `madd9`, `dom7b9`, `dom7s9`, `dom7b5`, `dom7s5`.
+- Playing patterns are now saved with the project and restored on load.
+
+### Changed
+- `at` now consumes the entire stack for time offsets; polyphony multiplies with deltas (2 notes × 2 times = 4 voices).
+- Iterator (`iter`) now resets when a pattern restarts.
+- Project loading now properly resets state: stops all patterns, clears user variables/dictionary, and clears queued changes.
+
+### Removed
+- `tcycle` word (replaced by polyphonic parameter behavior).
+
+## [0.0.2] - 2026-02-01
+- CI testing and codebase cleanup
+
+## [0.0.1] - Initial Release
+- CI testing

-## About live coding
-
-Live coding is a technique where a programmer writes code in real-time in front of an audience. It is a way to experiment with code, to share things and thoughts openly, to express yourself through code. It can be technical, poetical, weird, preferably all at once. Live coding can be used to create music, visual art, and other forms of media. Learn more about live coding on [https://toplap.org](https://toplap.org) or [https://livecoding.fr](https://livecoding.fr). Live coding is an autotelic activity: it is an activity that is intrinsically rewarding, and the act of doing it is its own reward. There are no errors, only fun to be found by playing music.
-
-## About the tool
-
-I do not want to pair it with a DAW, I do not want to make it fit with other commercial software. I'm not interested in VSTs or other proprietary workstations. Please, try to think of Cagire as an alternative to other tools.

+# About Forth
+
+Forth is a _stack-based_ programming language created by Charles H. Moore in the early 1970s. It was designed with simplicity, directness, and interactive exploration in mind. Forth has been used for many years to do scientific work and program embedded systems: it was used to control telescopes and was running on some devices used in space missions among other things. Forth quickly evolved into multiple implementations targetting various computer architectures. None of them really took off and became popular. Nonetheless, the ideas behind Forth continue to garner the interest of many different people in very different (often unrelated) fields. Nowadays, Forth languages are used by hackers and artists for their peculiarity. Forth is simple, direct and beautiful to implement. Forth is an elegant and minimal language to learn. It is easy to understand, to extend and to apply to a specific task. The Forth we use in Cagire is specialized in making live music. We think of it as a DSL: a _Domain Specific Language_. 
+
+## Why Forth?
+
+Most programming languages nowadays use a complex syntax made of `variables`, `expressions` and `statements` like `x = 3 + 4`. Forth works differently. It is way more simple than that, has almost no syntax and performs computations in a quite unique way. You push values onto a `stack` and apply `words` that transform them:
+
+```forth
+3 4 +
+```
+
+This program leaves the number `7` on the stack. There are no variables, no parentheses, no syntax to remember. You just end up with words and numbers separated by spaces. For live coding music, this directness is quite exciting. All you do is think in terms of transformations and add things to the stack: take a note, shift it up, add reverb, play it.
+
+## The Stack
+
+The stack is where values live. When you type a number, it goes on the stack. When you type a word, it usually takes values off and puts new ones back.
+
+```forth
+3       ( stack: 3 )
+4       ( stack: 3 4 )
++       ( stack: 7 )
+```
+
+The stack is `last-in, first-out`. The most recent value is always on top. This means that its often better to read Forth programs from the end to the beginning: from right to left, from the bottom to the top.
+
+## Words
+
+Everything in Forth is either a `number` or a `word`. Words are like functions but conceptually simpler. They have no arguments or return values in the traditional sense. They just manipulate the stack directly.
+
+```forth
+dup     ( duplicate the top value )
+drop    ( discard the top value )
+swap    ( swap the top two values )
+```
+
+Words compose naturally on the stack. To double a number:
+
+```forth
+3 dup +   ( 3 3 +)
+```
+
+There are a lot of words in a Forth and thus, Cagire has a `Dictionary` embedded directly into the application. You can also create your own words. They will work just like the already existing words. There are good reasons to create new words on-the-fly:
+
+- To make synth definitions.
+- To abstract _some piece of code_ that you use frequently.
+- To share data and processes between different steps.
+
+## Values
+
+Four types of values can live on the stack:
+
+- **Integers**: `42`, `-7`, `0`
+- **Floats**: `0.5`, `3.14`, `-1.0`
+- **Strings**: `"kick"`, `"hello"`
+- **Quotations**: `{ dup + }` (code as data)
+
+Quotations are special. They let you pass code around as a value. This is how conditionals and loops work. Think nothing of it for now, you will learn more about how to use it later on.
+
+## Stack Notation
+
+Documentation uses a notation to show what words do:
+
+```
+( before -- after )
+```
+
+For example, `+` has the signature `( a b -- sum )`. It takes two values and leaves one.
+
+## The Command Register
+
+Traditional Forth programs print text to a terminal. Cagire's Forth builds sound commands instead. This happens through an invisible accumulator called the command register. The command register has two parts:
+- a **sound name** (what instrument to play)
+- a list of **parameters** (how to play it)
+
+Three types of words interact with it:
+
+```forth
+kick sound      ;; sets the sound name
+0.5 gain        ;; adds a parameter
+.               ;; emits the command and clears the register
+```
+
+The word `sound` (or its shorthand `s`) sets what sound to play. Parameter words like `gain`, `freq`, `decay`, or `verb` add key-value pairs to the register. Nothing happens until you emit with `.` (dot). At that moment, the register is packaged into a command and sent to the audio engine.
+
+This design lets you build sounds incrementally:
+
+```forth
+"sine" sound
+c4 note
+0.5 gain
+0.3 decay
+0.4 verb
+.
+```
+
+Each line adds something to the register. The final `.` triggers the sound. You can also write it all on one line:
+
+```forth
+"sine" s c4 note 0.5 gain 0.3 decay 0.4 verb .
+```
+
+The order of parameters does not matter. You can even emit multiple times in a single step. If you need to discard the register without emitting, use `clear`:
+
+```forth
+"kick" s 0.5 gain clear    ;; nothing plays, register is emptied
+"hat" s .                  ;; only the hat plays
+```
+
+This is useful when conditionals might cancel a sound before it emits.
+
+## More details
+
+- Each step has its own stack and independant runtime.
+- Word definitions and variable definitions are shared by all steps.

-# Audio Engine
-
-Cagire uses **Doux** as its audio engine ([https://doux.livecoding.fr](https://doux.livecoding.fr)). Doux is a standalone synthesis and sampling engine that receives commands as strings and turns them into sound. Doux is a fixed graph synthesizer, which means that the structure of the sound is defined by a fixed set of nodes and connections, and the parameters of these nodes can be adjusted to create different sounds. Doux is extremely versatile and you are likely to find it useful for a wide range of musical styles and genres.
-
-## How Sound is Produced
-
-When the sequencer hits an active step, the Forth script is compiled and executed. Each emit operation (`.`) generates a command string that is sent to Doux. The command encodes the sound name and all accumulated parameters. The following example script:
-
-```
-"saw" sound c4 note 0.5 gain 2000 lpf .
-```
-
-will produce a command string that Doux interprets to _play a saw wave at C4 with gain 0.5 and a 2kHz lowpass filter_.
-
-## Sound sources
-
-Each sound needs a source. Sources are defined by typing their name followed by the `sound` keyword. Sources are raw waveforms or samples. They are shaped by passing additional parameters that will modify the characteristics of the sound: envelopes, effects, synthesis options, etc. The following example defines a source named `saw` with a frequency of 440 Hz, a gain of 0.5 and some reverb:
-
-```
-"saw" source 440 freq 0.5 gain 0.5 verb .
-```
-
-The audio engine offers a vast array (~20+) of sources including oscillators, noises, live input, and more.
-
-## Settings
-
-- **Channels**: Output channel count (1-64)
-- **Buffer Size**: Audio buffer in samples (64-4096). Lower values reduce latency but increase CPU load.
-- **Voices**: Maximum polyphony (1-128, default 32). When the limit is reached, the oldest voice is stolen.
-
-Settings are persisted across sessions.
-
-## Samples
-
-Cagire scans sample directories recursively and indexes all audio files. Add sample paths on the Engine page with **a**, remove with **d**. Use samples in scripts by name:
-
-```
-"kick" s .
-"hat" s 0.5 gain .
-```
-
-The sample index is shown on the Engine page with the total count.
-
-## Visualizers
-
-The Engine page displays two real-time visualizers:
-
-- **Scope**: Waveform display (64 samples), updated on every audio callback
-- **Spectrum**: 32-band FFT analyzer with logarithmic frequency scaling (20Hz to Nyquist), Hann window, displayed in dB
-
-Both can be toggled on or off in the Options page.
-
-## Monitoring
-
-The Engine page shows live metrics:
-
-- **Active voices**: Current polyphony count
-- **Peak voices**: Highest voice count since last reset (press **r** to reset)
-- **CPU load**: Audio thread utilization
-- **Events**: Total emitted and dropped event counts
-
-## Tempo Scaling
-
-Some parameters are automatically scaled by step duration so they sound consistent across tempos. These include envelope times (attack, decay, release), filter envelopes, pitch envelopes, FM envelopes, glide, and reverb/delay times.
-
-## Commands
-
-On the Engine page:
-
-- **h**: Hush (graceful fade-out of all voices)
-- **p**: Panic (hard stop all voices immediately)
-- **r**: Reset peak voice counter
-- **t**: Test sound (plays a 440Hz sine)

+# Banks & Patterns
+
+Cagire organizes all your patterns and data following a strict hierarchy:
+
+- **Projects** contain **Banks**.
+- **Banks** contain **Patterns**.
+- **Patterns** contain **Steps**.
+
+## Structure
+
+```
+Project
+└── 32 Banks
+    └── 32 Patterns (per bank)
+        └── 128 Steps (per pattern)
+```
+
+A single project gives you 32 banks, each holding 32 patterns. You get 1024 patterns in each project, ~131.000 steps.
+
+## Patterns
+
+Each pattern is an independent sequence of steps with its own properties:
+
+| Property | Description | Default |
+|----------|-------------|---------|
+| Length | Steps before the pattern loops (`1`-`128`) | `16` |
+| Speed | Playback rate (`1/8x` to `8x`) | `1x` |
+| Quantization | When the pattern launches | `Bar` |
+| Sync Mode | Reset or Phase-Lock on re-trigger | `Reset` |
+
+Press `e` in the patterns view to edit these settings.
+
+## Patterns View
+
+Access the patterns view with `Ctrl+Up` from the sequencer. The view shows all banks and patterns in a grid. Indicators show pattern state:
+
+- `>` Currently playing
+- `+` Staged to play
+- `-` Staged to stop
+
+### Keybindings
+
+| Key | Action |
+|-----|--------|
+| `Arrows` | Navigate banks and patterns |
+| `Enter` | Select and return to sequencer |
+| `Space` | Toggle pattern playback |
+| `e` | Edit pattern properties |
+| `r` | Rename bank or pattern |
+| `c` / `v` | Copy / Paste |
+| `Delete` | Reset to empty pattern |

+# Creating Words
+
+One of Forth's most powerful features is the ability to define new words. A word definition gives a name to a sequence of operations. Once defined, you can use the new word just like any built-in word.
+
+## The Syntax
+
+Use `:` to start a definition and `;` to end it:
+
+```forth
+: double dup + ;
+```
+
+This creates a word called `double` that duplicates the top value and adds it to itself. Now you can use it:
+
+```forth
+3 double    ;; leaves 6 on the stack
+5 double    ;; leaves 10 on the stack
+```
+
+The definition is simple: everything between `:` and `;` becomes the body of the word.
+
+## Definitions Are Shared

+When you define a word in one step, it becomes available to all other steps. This is how you share code across your pattern. Define your synths, rhythms, and utilities once, then use them everywhere.
+
+Step 0:
+```forth
+: bass "saw" s 0.8 gain 800 lpf ;
+```
+
+Step 4:
+```forth
+c2 note bass .
+```
+
+Step 8:
+```forth
+g2 note bass .
+```
+
+The `bass` word carries the sound design. Each step just adds a note and plays.
+
+## Redefining Words
+
+You can redefine any word, including built-in ones:
+
+```forth
+: dup drop ;
+```
+
+Now `dup` does the opposite of what it used to do. This is powerful but dangerous. Redefining core words can break things in subtle ways.
+
+You can even redefine numbers:
+
+```forth
+: 2 4 ;
+```
+
+Now `2` pushes `4` onto the stack. The number two no longer exists in your session. This is a classic Forth demonstration: nothing is sacred, everything can be redefined. 
+
+## Practical Uses
+
+**Synth definitions** save you from repeating sound design:
+
+```forth
+: pad "sine" s 0.3 gain 2 attack 0.5 verb ;
+```
+
+**Transpositions** and musical helpers:
+
+```forth
+: octup 12 + ;
+: octdn 12 - ;
+```
+
+## Words That Emit
+
+A word can contain `.` to emit sounds directly:
+
+```forth
+: kick "kick" s . ;
+: hat "hat" s 0.4 gain . ;
+```
+
+Then a step becomes trivial:
+
+```forth
+kick hat
+```
+
+Two sounds, two words, no clutter.
+
+## Stack Effects
+
+When you create a word, think about what it expects on the stack and what it leaves behind. The word `double` expects one number and leaves one number. The word `kick` expects nothing and leaves nothing (it emits a sound as a side effect). Well-designed words have clear stack effects. This makes them easy to combine.

+# The Dictionary
+
+Cagire includes a built-in dictionary of all the internal Forth words. Press `Ctrl+Up` to reach the **Dict** view.
+
+## Using the Dictionary
+
+The dictionary shows every available word organized by category:
+
+- **Stack**: Manipulation words like `dup`, `swap`, `drop`.
+- **Arithmetic**: Math operations.
+- **Sound**: Sound sources and emission.
+- **Filter**, **Envelope**, **Effects**: Sound shaping.
+- **MIDI**: External MIDI control (`chan`, `cc`, `emit`, `clock`, etc.).
+- **Context**: Sequencer state like `step`, `beat`, `tempo`.
+- And many more...
+
+This tutorial will not teach you how to use all words. The syntax is very uniform and you can quickly learn a new word when necessary. We encourage you to explore as you play, this is the best way to learn. The tutorial will remain focused on various topics that require you to apply knowledge to a given task or specific context.
+
+## Navigation
+
+| Key | Action |
+|-----|--------|
+| `Tab` | Switch between categories and words |
+| `↑/↓` or `j/k` | Navigate items |
+| `PgUp/PgDn` | Page through lists |
+| `/` or `Ctrl+F` | Search |
+| `Esc` | Clear search |
+
+Each word entry shows:
+
+- **Name** and aliases
+- **Stack effect**: `( before -- after )`
+- **Description**: What the word does
+- **Example**: How to use it
+
+Press `/` to search across all words. The search matches word names, aliases, and descriptions. Press `Esc` to clear and return to browsing.
+
+Use the dictionary while writing scripts to check stack effects and study their behavior. Some words also come with shorter aliases (e.g., `sound` → `s`). You will learn aliases quite naturally, because aliases are usually reserved for very common words.

+# Editing a Step
+
+Each step in Cagire contains a Forth script. When the sequencer reaches that step, it runs the script to produce sound. This is where you write your music. Press `Enter` when hovering over any step to open the `code editor`. The editor appears as a modal overlay with the step number in the title bar. If the step is a linked step (shown with an arrow like `→05`), pressing `Enter` navigates to the source step instead.
+
+## Writing Scripts
+
+Scripts are written in Forth. Type words and numbers separated by spaces. The simplest script that makes sound is:
+
+```forth
+sine sound .
+```
+
+Add parameters before words to modify them:
+
+```forth
+c4 note 0.75 decay sine sound .
+```
+
+Writing long lines is not recommended because it can become quite unmanageable. Instead, break them into multiple lines for clarity:
+
+```forth
+c4 note
+0.75 decay
+sine sound
+0.4 verb
+.
+```
+
+## Saving
+
+- `Esc` - Save and close the editor
+- `Ctrl+E` - Save without closing
+
+When you save, the script is compiled and sent to the sequencer. If there's an error, a message appears briefly at the bottom of the screen. You will also receive visual feedback in the form of a flashing window when saving / evaluating a script.
+
+## Completion
+
+As you type, the editor suggests matching Forth words. The completion list shows all built-in words that start with your current input. Press `Tab` to insert the selected suggestion, or `Esc` to dismiss the list. Use arrow keys to navigate between suggestions.
+
+Completion helps you discover words without memorizing them all. Type a few letters and browse what's available. For example, typing `ver` will suggest `verb` (reverb), typing `fil` will show filter-related words.
+
+## Debugging
+
+Press `Ctrl+S` to toggle the stack display. This shows the stack state evaluated up to the cursor line, useful for understanding how values flow through your script. Press `Ctrl+R` to execute the script immediately without waiting for the sequencer to reach the step.
+
+## Keybindings

+# Filters
+
+Filters attenuate frequencies above or below a cutoff point.
+
+## Lowpass Filter
+
+The lowpass filter (`lpf`) attenuates frequencies above the cutoff.
+
+```forth
+saw 1000 lpf .               ( cut above 1000 Hz )
+saw 500 lpf 0.8 lpq .        ( with resonance )
+```
+
+| Parameter | Range | Description |
+|-----------|-------|-------------|
+| `lpf` | Hz | Cutoff frequency |
+| `lpq` | 0-1 | Resonance (peak at cutoff) |
+
+## Highpass Filter
+
+The highpass filter (`hpf`) attenuates frequencies below the cutoff.
+
+```forth
+kick 200 hpf .               ( cut below 200 Hz )
+pad 400 hpf 0.3 hpq .        ( with resonance )

+
+| Parameter | Range | Description |
+|-----------|-------|-------------|
+| `bpf` | Hz | Center frequency |
+| `bpq` | 0-1 | Resonance (narrower band) |
+
+## Filter Slope
+
+The `ftype` parameter sets the filter slope (rolloff steepness).
+
+| Value | Slope |
+|-------|-------|
+| `1` | 12 dB/octave |
+| `2` | 24 dB/octave (default) |

+
+## Filter Envelope
+
+Filters can be modulated by an ADSR envelope. The envelope multiplies the base cutoff:
+
+```
+final_cutoff = lpf + (lpe × envelope × lpf)
+```
+
+When the envelope is at 1.0 and `lpe` is 1.0, the cutoff doubles. When the envelope is at 0, the cutoff equals `lpf`.

+# Introduction
+
+Cagire includes an audio engine called `Doux`. No external software is needed to make sound. `Doux` is an opinionated, semi-modular synthesizer. It was designed for live coding environments and works by receiving command strings that describe sounds. Despite its fixed architecture,`Doux` is extremely versatile and will likely cover most of the audio needs of a live coder.
+
+## How It Works
+
+When you write a Forth script and emit (`.`), the script produces a command string. This command travels to the audio engine, which interprets it and creates a voice. The voice plays until its envelope finishes or until it is killed by another voice. You can also spawn infinite voices, but you will need to manage their lifecycle manually, otherwise they will never stop.
+
+```forth
+saw s c4 note 0.8 gain 0.3 verb .
+```
+
+## Voices
+
+Each `emit` (`.`) creates or manages a voice by sending parameters. Voices are independent sound generators with their own oscillator, envelope, and effects. The engine can run many voices at once (up to `128`, default `32`). When you exceed the voice limit, the oldest voice is stolen (a process called _round robin scheduling_). You can monitor voice usage on the Engine page:
+
+- **Active voices**: how many are playing right now.
+- **Peak voices**: the maximum reached since last reset.
+
+Press `r` on the Engine page to reset the peak counter.
+
+## Parameters
+
+After selecting a sound source, you add parameters. Each parameter word takes a value from the stack and stores it in the command register:
+
+```forth
+saw s
+  c4 note        ;; pitch
+  0.5 gain       ;; volume
+  0.1 attack     ;; envelope attack time
+  2000 lpf       ;; lowpass filter at 2kHz
+  0.3 verb       ;; reverb mix
+.
+```
+
+Parameters can appear in any order. They accumulate until you emit. You can clear the register using the `clear` word.
+
+## Controlling Existing Voices
+
+You can emit without a sound name. In this case, no new voice is created. Instead, the parameters are sent to control an existing voice. Use `voice` with an ID to target a specific voice:
+
+```forth
+0 voice 500 freq .   ;; change frequency on voice 0
+```
+
+This is useful for modulating long-running or infinite voices. Set up a drone on one step with a known voice ID, then tweak its parameters from other steps.
+
+## Hush and Panic
+
+Two emergency controls exist on the Engine page:
+
+- `h` - **Hush**: gracefully fade out all voices
+- `p` - **Panic**: immediately kill all voices
+
+Use hush when things get too loud. Use panic when things go wrong.

+# Samples
+
+The `sample` source plays audio files from disk with pitch tracking.
+
+## Loading Samples
+
+There are two ways to load samples:
+
+* **From the app:** Navigate to the Engine view and find the Samples section. Press `A` to open a file browser, then select a folder containing your samples. Press `D` to remove the last added path.
+
+* **From the command line:** Use the `-s` flag when launching Cagire:
+
+```
+cagire -s ~/samples -s ~/more-samples
+```
+
+The engine scans these directories and builds a registry of available samples. Samples load in the background without blocking audio. Supported file formats are `.wav`, `.mp3`, `.ogg`, `.flac` and `.aiff`.
+
+## Folder Organization
+
+```
+samples/
+├── kick.wav           → "kick"
+├── snare.wav          → "snare"
+└── hats/
+    ├── closed.wav     → "hats" n 0
+    ├── open.wav       → "hats" n 1
+    └── pedal.wav      → "hats" n 2
+```
+
+Folders at the root of your directory are used as the name of a sample bank. Folders create sample banks where each file gets an index. Files are sorted alphabetically and assigned indices starting from `0`.
+
+## Playing Samples
+
+```forth
+kick sound .                     ( play kick sample )
+hats sound 2 n .                 ( play third hat sample )
+snare sound  0.5 speed .         ( play snare at half speed )
+```
+
+## Parameters
+
+| Parameter | Range | Description |
+|-----------|-------|-------------|
+| `n` | 0+ | Sample index within a folder (wraps around) |
+| `begin` | 0-1 | Playback start position |
+| `end` | 0-1 | Playback end position |
+| `speed` | any | Playback speed multiplier |
+| `freq` | Hz | Base frequency for pitch tracking |
+| `fit` | seconds | Stretch/compress sample to fit duration |
+| `cut` | 0+ | Choke group |
+
+## Slicing with Begin/End
+
+The `begin` and `end` parameters define what portion of the sample plays. Values are normalized from 0 (start) to 1 (end).
+
+```forth
+kick sound 0.25 begin 0.75 end .   ( play middle half )
+kick sound 0.5 begin .             ( play second half )
+kick sound 0.5 end .               ( play first half )
+```
+
+If begin is greater than end, they swap automatically.
+
+## Speed and Pitch
+
+The `speed` parameter affects both tempo and pitch. A speed of 2 plays twice as fast and an octave higher.
+
+```forth
+snare sound 2 speed .              ( double speed, octave up )
+snare sound 0.5 speed .            ( half speed, octave down )
+snare sound -1 speed .             ( play in reverse )
+```
+
+For pitched playback, use `freq` or note names. The sample's base frequency defaults to middle C (261.626 Hz).
+
+```forth
+kick sound 440 freq .              ( play at A4 )
+kick sound c4 .                    ( play at C4 )
+```
+
+Negative speed will reverse the sample and play it backwards.
+
+```forth
+crow sound -1 speed .              ( play backwards at nominal speed )
+crow sound -4 speed .              ( play backwards, 4 times faster )
+```
+
+## Fitting to Duration
+
+The `fit` parameter stretches or compresses a sample to match a target duration in seconds. This adjusts speed automatically.
+
+```forth
+kick sound 0.25 fit .              ( fit kick into quarter second )
+snare sound beat fit .             ( fit snare to one beat )
+```
+
+## Choke Groups
+
+The `cut` parameter assigns a sample to a choke group. When a new sample with the same cut value plays, it kills any currently playing samples in that group.
+
+```forth
+hihat_closed sound 1 cut .         ( choke group 1 )
+hihat_open sound 1 cut .           ( kills closed hat, starts open )
+```
+
+This is essential for realistic hi-hat behavior where open and closed hats shouldn't overlap.
+
+## Bank Variations
+
+Add `_suffix` to sample names to create variations that share the same base name.
+
+```
+samples/
+├── kick.wav
+├── kick_hard.wav
+├── kick_soft.wav
+```
+
+Select variations with the `bank` parameter:
+
+```forth
+kick sound .                       ( plays kick.wav )
+kick sound hard bank .             ( plays kick_hard.wav )
+kick sound soft bank .             ( plays kick_soft.wav )
+```

+Smaller buffers mean lower latency but higher CPU load. Larger buffers are safer but feel sluggish.
+
+| Buffer | Latency at 44.1kHz |
+|--------|-------------------|
+| 64     | ~1.5ms            |
+| 128    | ~3ms              |
+| 256    | ~6ms              |
+| 512    | ~12ms             |
+| 1024   | ~23ms             |
+
+Start with 512. Lower it if you need tighter timing. Raise it if you hear glitches.
+
+## Samples
+
+The engine indexes audio files from your sample directories. Add directories with `A`, remove with `D`. The sample count shows how many files are indexed.
+
+### Supported Formats
+
+- WAV (.wav)
+- MP3 (.mp3)
+- OGG Vorbis (.ogg)
+- FLAC (.flac)
+- AIFF (.aiff, .aif)
+- AAC (.aac)
+- M4A (.m4a)
+
+### Lazy Loading
+
+Samples are not loaded into memory at startup. They are decoded on demand when first played. This means you can have thousands of samples indexed without using much RAM until you actually use them.
+
+### Folder Organization
+
+The scanner looks at top-level files and one level of subdirectories:
+
+```
+samples/
+├── kick.wav           -> "kick"
+├── snare.wav          -> "snare"
+├── hats/
+│   ├── closed.wav     -> "hats" n 0
+│   ├── open.wav       -> "hats" n 1
+│   └── pedal.wav      -> "hats" n 2
+└── breaks/
+    ├── amen.wav       -> "breaks" n 0
+    └── think.wav      -> "breaks" n 1
+```
+
+Top-level files are named by their filename (without extension). Files inside folders are sorted alphabetically and numbered starting from 0.
+
+### Playing Samples
+
+Reference samples by name:
+
+```forth
+kick s .              ;; play kick.wav
+snare s 0.5 gain .    ;; play snare at half volume
+```
+
+For samples in folders, use `n` to select which one:
+
+```forth
+hats s 0 n .          ;; play hats/closed.wav (index 0)
+hats s 1 n .          ;; play hats/open.wav (index 1)
+hats s 2 n .          ;; play hats/pedal.wav (index 2)
+```
+
+The index wraps around. If you have 3 samples and request `5 n`, you get index 2 (because 5 % 3 = 2).
+
+### Sample Variations with Bank
+
+The `bank` parameter lets you organize variations:
+
+```
+samples/
+├── kick.wav          -> default
+├── kick_a.wav        -> bank "a"
+├── kick_b.wav        -> bank "b"
+└── kick_hard.wav     -> bank "hard"
+```
+
+```forth
+kick s .              ;; plays kick.wav
+kick s a bank .       ;; plays kick_a.wav
+kick s hard bank .    ;; plays kick_hard.wav
+```
+
+If the banked version does not exist, it falls back to the default.
+
+## Troubleshooting
+
+* **No sound**: Check output device selection.
+  * Try the test sound (`t`) on Engine page).
+
+* **Glitches/crackling**: Increase buffer size, restart the Engine.
+
+* **High CPU**: Reduce max voices. Disable scope/spectrum. Increase buffer size.
+
+* **Samples not found**: Check sample directories on Engine page. Filenames are case-sensitive on some systems.

+# Sources
+
+The audio engine provides a variety of sound sources. Use the `sound` word (or `s` for short) to select one.
+
+## Basic Oscillators
+
+| Name | Description |
+|------|-------------|
+| `sine` | Pure sinusoid, smooth and mellow |
+| `tri` | Triangle wave, warmer than sine, naturally band-limited |
+| `saw` | Bright sawtooth with anti-aliasing, rich in harmonics |
+| `zaw` | Raw sawtooth without anti-aliasing, lo-fi character |
+| `pulse`, `square` | Variable-width pulse wave with anti-aliasing |
+| `pulze`, `zquare` | Raw pulse without anti-aliasing, 8-bit feel |
+
+`pulse` and `pulze` respond to the `pw` parameter (0.0-1.0) for pulse width. At 0.5 you get a square wave.
+
+### Phase Shaping
+
+All oscillators support phase shaping for timbral variation:
+
+| Parameter | Range | Effect |
+|-----------|-------|--------|
+| `size` | 0-256 | Phase quantization (lo-fi, chiptune). |
+| `mult` | 0.25-16 | Phase multiplier (harmonic overtones). |
+| `warp` | -1 to 1 | Power curve asymmetry. |
+| `mirror` | 0-1 | Phase reflection point. |
+
+These are super useful to get the most out of your oscillators.
+
+### Sub Oscillator
+
+Add a sub oscillator layer to any basic oscillator:
+
+| Parameter | Range | Effect |
+|-----------|-------|--------|
+| `sub` | 0-1 | Mix level |
+| `suboct` | 1-3 | Octaves below main. |
+| `subwave` | tri/sine/square | Sub waveform. |
+
+## Noise
+
+| Name | Description |
+|------|-------------|
+| `white` | Equal energy across all frequencies, bright and hissy. |
+| `pink` | -3dB/octave rolloff, equal energy per octave, natural. |
+| `brown` | -6dB/octave rolloff, deep rumbling, random walk. |
+
+Noise sources ignore pitch. Use filters to shape the spectrum.
+
+## Live Input
+
+| Name | Description |
+|------|-------------|
+| `live`, `livein`, `mic` | Live audio input from microphone or line-in |
+
+All filter and effect parameters apply to the input signal.
+
+## Plaits Engines
+
+The Plaits engines come from Mutable Instruments and provide a range of synthesis methods. Beware, these sources can be quite CPU hungry. All share three control parameters (`0.0`-`1.0`):
+
+| Parameter | Controls |
+|-----------|----------|
+| `harmonics` | Harmonic content, structure, detuning. |
+| `timbre` | Brightness, tonal color. |
+| `morph` | Smooth transitions between variations. |
+
+### Pitched
+
+| Name | Description |
+|------|-------------|
+| `modal` | Struck/plucked resonant bodies (strings, plates, tubes). |
+| `va`, `analog` | Virtual analog with waveform sync and crossfading. |
+| `ws`, `waveshape` | Waveshaper and wavefolder. |
+| `fm2` | Two-operator FM synthesis with feedback. |
+| `grain` | Granular formant oscillator (vowel-like). |
+| `additive` | Harmonic additive synthesis. |
+| `wavetable` | Built-in Plaits wavetables (four 8x8 banks). |
+| `chord` | Four-note chord generator. |
+| `swarm` | Granular cloud of enveloped sawtooths. |
+| `pnoise` | Clocked noise through multimode filter. |
+
+### Percussion
+
+| Name | Description |

+| `kick`, `bass` | 808-style bass drum. |
+| `snare` | Analog snare drum with tone/noise balance. |
+| `hihat`, `hat` | Metallic 808-style hi-hat. |
+
+Percussions are super hard to use correctly, because you need to tweak their envelope correctly.

+# Wavetables
+
+Any sample can be played as a wavetable. When you use the `scan` parameter, the sample automatically becomes a pitched oscillator that can morph between cycles.
+
+## What is a Wavetable?
+
+A wavetable is a series of single-cycle waveforms stored end-to-end in an audio file. Each cycle is a complete waveform that starts and ends at zero crossing, allowing it to loop seamlessly at any pitch.
+
+```
+Sample: [cycle 0][cycle 1][cycle 2][cycle 3]
+         ↑                           ↑
+      scan 0                      scan 1
+```
+
+The oscillator reads through one cycle at audio rate (determining pitch), while `scan` selects which cycle to play. Values between cycles crossfade smoothly, creating timbral morphing.
+
+## Basic Usage
+
+Just add `scan` to any sample and it becomes a wavetable:
+
+```forth
+pad 0 scan .                 ( play pad as wavetable, first cycle )
+pad 0.5 scan .               ( blend to middle cycles )
+pad 440 freq 0 scan .        ( play at A4 )
+```
+
+Without `scan`, the sample plays normally. With `scan`, it becomes a looping wavetable oscillator.
+
+## Parameters
+
+| Parameter | Range | Description |
+|-----------|-------|-------------|
+| `scan` | 0-1 | Position in wavetable (0 = first cycle, 1 = last) |
+| `wtlen` | samples | Cycle length in samples (0 = entire sample) |
+| `scanlfo` | Hz | LFO rate for scan modulation |
+| `scandepth` | 0-1 | LFO modulation depth |
+| `scanshape` | shape | LFO waveform |
+
+## Cycle Length
+
+The `wtlen` parameter tells the engine how many samples make up one cycle. This must match how the wavetable was created, otherwise you'll hear the wrong pitch or glitchy artifacts.
+
+```forth
+pad 0 scan 2048 wtlen .      ( Serum-style 2048-sample cycles )
+pad 0 scan 1024 wtlen .      ( 1024-sample cycles )
+```
+
+Common cycle lengths are powers of two: 256, 512, 1024, 2048. Serum uses 2048 samples per cycle. The number of cycles in a wavetable is the total sample length divided by `wtlen`. If `wtlen` is 0 (default), the entire sample is treated as one cycle. The sample still loops as a pitched oscillator, but `scan` has no morphing effect since there's only one cycle.
+
+## Scanning
+
+The `scan` parameter selects which cycle to play:
+
+```forth
+pad 0 scan .                 ( first cycle only )
+pad 0.5 scan .               ( blend between middle cycles )
+pad 1 scan .                 ( last cycle only )
+```
+
+## LFO Modulation
+
+Automate the scan position with a built-in LFO:
+
+```forth
+pad 0 scan 2 scanlfo 0.3 scandepth .   ( 2 Hz modulation, 30% depth )
+```
+
+Available LFO shapes:
+
+| Shape | Description |
+|-------|-------------|
+| `sine` | Smooth oscillation (default) |
+| `tri` | Triangle wave |
+| `saw` | Sawtooth, ramps up |
+| `square` | Alternates between extremes |
+| `sh` | Sample and hold, random steps |
+
+## Creating Wavetables
+
+A proper wavetable file:
+
+- Contains multiple single-cycle waveforms of identical length
+- Each cycle starts and ends at zero crossing for seamless looping
+- Uses power-of-two cycle lengths (256, 512, 1024, 2048)
+- Has cycles that morph smoothly from one to the next
+
+You can find wavetable packs online or create your own in tools like Serum, WaveEdit, or Audacity (using zero-crossing snap). Single-cycle waveforms also work. With `wtlen` set to 0, a single-cycle sample becomes a basic pitched oscillator.

+# The Sequencer Grid
+
+The sequencer grid is the main view of Cagire. This is the one you see when you open the application. On this view, you can see the step sequencer grid and edit each step using the `code editor`. At the top, you can optionally display an oscilloscope and a spectrum analyzer.
+
+## Navigation
+
+Use arrow keys to move between steps. The grid wraps around at pattern boundaries. You can move in any direction.
+
+## Preview
+
+Press `P` to enter preview mode. In preview mode, a view-only code editor opens so that you can see the script of the currently playing step. While in preview mode, you can still move around the grid. Press `Esc` to exit preview mode.
+
+## Selection
+
+Hold `Shift` while pressing arrow keys to select multiple steps. Press `Esc` to clear the selection.
+
+## Editing Steps
+
+- `Enter` - Open the script editor.
+- `t` - Toggle step active/inactive.
+- `r` - Rename a step.
+- `Del` - Delete selected steps.
+
+## Copy & Paste
+
+- `Ctrl+C` - Copy selected steps.
+- `Ctrl+V` - Paste as copies.
+- `Ctrl+B` - Paste as linked steps.
+- `Ctrl+D` - Duplicate selection.
+- `Ctrl+H` - Harden links (convert to copies).
+
+`Linked steps` share the same script as their source. When you edit the source, all linked steps update automatically. This is an extremely important and powerful feature. It allows you to create complex patterns with minimal effort. `Ctrl+H` is your best friend to manage linked steps and convert them to real steps. 
+
+## Pattern Controls
+
+- `<` / `>` - Decrease/increase pattern length
+- `[` / `]` - Decrease/increase pattern speed
+- `L` - Set length directly
+- `S` - Set speed directly

+# How Does It Work?
+
+Cagire is a step sequencer where each step contains a **Forth script** instead of the typical note data. When the sequencer reaches a step, it runs the script. A script _can do whatever it is programed to do_, such as producing sound commands sent to an internal audio engine. Everything else is similar to a step sequencer: you can `toggle` / `untoggle`, `copy` / `paste` any step or group of steps, etc. You are completely free to define what your scripts will do. It can be as simple as playing a note, or as complex as triggering random audio samples with complex effects. Scripts can also share code and data with each other.
+
+## Project / session organization
+
+Cagire can run multiple patterns concurrently. Each pattern contains a given number of steps. Every session / project is organized hierarchically:
+
+- **32 Banks** 
+- **32 Patterns** per bank
+- **128 Steps** per pattern
+
+That's over 130,000 possible steps per project. Most of my sessions use 15-20 at best.
+
+## What does a script look like?
+
+Forth is a stack-based programming language. It is very minimalistic and emphasizes simplicity and readability. Using Forth doesn't feel like programming at all. It feels more like juggling with words and numbers or writing bad computer poetry. There is pretty much no syntax to learn, just a few rules to follow. Forth is ancient, powerful, flexible, and... super fun to live code with! Here is a minimal program that will play a middle C note using a sine wave:
+
+```forth
+c4 note sine sound .
+```
+
+Read the program backwards and you will understand what it does instantly:
+
+- `.`: we want to play a sound.
+- `sine sound`: the sound is a sinewave.
+- `c4 note`: the pitch is C4 (middle-C).
+
+Scripts can be simple one-liners or complex programs with conditionals, loops, and randomness. They tend to look like an accumulation of words and numbers. Use space and line returns to your advantage. The Forth language can be learned... on the spot. You just need to understand the following basic rules:
+
+- there are `words` and `numbers`.
+- they are delimited by spaces.
+- everything piles up on the `stack`.
+
+Obviously you will need to understand what the **stack** is, but it will take you five minutes. That's it. See the **Forth** section for details.
+
+## The Audio Engine
+
+Cagire includes a complete synthesis engine. No external software is required to play music. It comes with a large number of sound sources and sound shaping tools: oscillators, sample players, effects, filters, and more. The audio engine is quite capable and versatile, and can accomodate a vast array of genres / styles. Here are a few examples :
+
+```forth
+;; sawtooth wave with lowpass filter, chorus and reverb
+saw sound 1200 lpf 0.2 chorus 0.8 verb .
+```
+
+```forth
+;; pure sine wave with vibrato and bit crushing
+0.5 vibmod 4 vib sine sound 8 crush 0.8 gain .
+```
+
+```forth
+;; very loud and pitched-down kick drum using an audio sample
+kkick sound 1.5 distort 0.9 postgain 0.8 speed .
+```
+
+## Timing & Synchronization
+
+Cagire uses **Ableton Link** to manage timing and synchronization. This means that all devices using the same protocol can be synchronized to the same tempo. Most commercial softwares support this protocol. The playback speed is defined as a BPM (beats per minute) value. Patterns can run at different speeds relative to the master tempo. Most of the durations in Cagire are defined in terms of beats.

+# MIDI Input
+
+Read incoming MIDI control change values with the `ccval` word. This lets you use hardware controllers to modulate parameters in your scripts.
+
+## Reading CC Values
+
+The `ccval` word takes a CC number and channel from the stack, and returns the last received value:
+
+```forth
+1 1 ccval   ;; read CC 1 (mod wheel) on channel 1
+```
+
+Stack effect: `(cc chan -- val)`
+
+The returned value is `0`-`127`. If no message has been received for that CC/channel combination, the value is `0`.
+
+## Device Selection
+
+Use `dev` to select which input device slot to read from:
+
+```forth
+1 dev 1 1 ccval   ;; read from device slot 1
+```
+
+Device defaults to `0` if not specified.
+
+## Practical Examples
+
+Map a controller knob to filter cutoff:
+
+```forth
+74 1 ccval 127 / 200 2740 range lpf
+```
+
+Use mod wheel for vibrato depth:
+
+```forth
+1 1 ccval 127 / 0 0.5 range vibdepth
+```
+
+Crossfade between two sounds:
+
+```forth
+1 1 ccval 127 /    ;; normalize to 0.0-1.0
+dup saw s swap gain .
+1 swap - tri s swap gain .
+```
+
+## Scaling Values
+
+CC values are integers `0`-`127`. Normalize to `0.0`-`1.0` first, then use `range` to scale:
+
+```forth
+;; normalize to 0.0-1.0
+74 1 ccval 127 /
+
+;; scale to custom range (e.g., 200-4000)
+74 1 ccval 127 / 200 4000 range
+
+;; bipolar range (-1.0 to 1.0)
+74 1 ccval 127 / -1 1 range
+```
+
+The `range` word takes a normalized value (`0.0`-`1.0`) and scales it to your target range: `(val min max -- scaled)`.
+
+## Latency
+
+CC values are sampled at the start of each step. Changes during a step take effect on the next step. For smoothest results, turn knobs slowly or use higher step rates.

+Cagire speaks MIDI. You can send notes, control changes, and other messages to external synthesizers, drum machines, and DAWs. You can also read incoming control change values from MIDI controllers and use them to modulate your scripts.
+
+## Device Slots
+
+Cagire provides four input slots and four output slots, numbered `0` through `3`. Each slot can connect to one MIDI device. By default, slot `0` is used for both input and output.
+
+## Configuration
+
+Configure your MIDI devices in the **Options** view. Select input and output devices for each slot. Changes take effect immediately.
+
+## MIDI vs Audio
+
+The audio engine (`Doux`) and MIDI are independent systems. Use `.` to emit audio commands, use `m.` to emit MIDI messages. You can use both in the same script:
+
+```forth
+saw s c4 note 0.5 gain .  ;; audio
+60 note 100 velocity m.   ;; MIDI
+```
+
+MIDI is useful when you want to sequence external gear, layer Cagire with hardware synths, or integrate into a larger studio setup. The audio engine is self-contained and needs no external equipment.
+
+## Clock and Transport
+
+Cagire can send MIDI clock and transport messages to synchronize external gear. Use `mclock` to send a single clock pulse, and `mstart`, `mstop`, `mcont` for transport control. MIDI clock requires 24 pulses per quarter note, so you need to call `mclock` at the appropriate rate for your tempo.

+# MIDI Output
+
+Send MIDI messages using the `m.` word. Build up parameters on the stack, then emit. The system determines message type based on which parameters you set.
+
+## Note Messages
+
+The default message type is a note. Set `note` and `velocity`, then emit:
+
+```forth
+60 note 100 velocity m.   ;; middle C, velocity 100
+c4 note 80 velocity m.    ;; same pitch, lower velocity
+```
+
+| Parameter | Stack | Range | Description |
+|-----------|-------|-------|-------------|
+| `note` | `(n --)` | 0-127 | MIDI note number |
+| `velocity` | `(n --)` | 0-127 | Note velocity |
+| `chan` | `(n --)` | 1-16 | MIDI channel |
+| `dur` | `(f --)` | steps | Note duration |
+| `dev` | `(n --)` | 0-3 | Output device slot |
+
+Duration (`dur`) is measured in steps. If not set, the note plays until the next step. Channel defaults to `1`, device defaults to `0`.
+
+## Control Change
+
+Set both `ccnum` (controller number) and `ccout` (value) to send a CC message:
+
+```forth
+74 ccnum 64 ccout m.   ;; CC 74, value 64
+1 ccnum 127 ccout m.   ;; mod wheel full
+```
+
+| Parameter | Stack | Range | Description |
+|-----------|-------|-------|-------------|
+| `ccnum` | `(n --)` | 0-127 | Controller number |
+| `ccout` | `(n --)` | 0-127 | Controller value |
+
+## Pitch Bend
+
+Set `bend` to send pitch bend. The range is `-1.0` (full down) to `1.0` (full up), with `0.0` as center:
+
+```forth
+0.5 bend m.    ;; bend up halfway
+-1.0 bend m.   ;; full bend down
+```
+
+## Channel Pressure
+
+Set `pressure` to send channel aftertouch:
+
+```forth
+64 pressure m.   ;; medium pressure
+```
+
+## Program Change
+
+Set `program` to send a program change message:
+
+```forth
+0 program m.    ;; select program 0
+127 program m.  ;; select program 127
+```
+
+## Message Priority
+
+When multiple message types are set, only one is sent per emit. Priority order:
+
+1. Control Change (if `ccnum` AND `ccout` set)
+2. Pitch Bend
+3. Channel Pressure
+4. Program Change
+5. Note (default)
+
+To send multiple message types, use multiple emits:
+
+```forth
+74 ccnum 100 ccout m.   ;; CC first
+60 note 100 velocity m. ;; then note
+```
+
+## Real-Time Messages
+
+Transport and clock messages for external synchronization:
+
+| Word | Description |
+|------|-------------|
+| `mclock` | Send MIDI clock pulse |
+| `mstart` | Send MIDI start |
+| `mstop` | Send MIDI stop |
+| `mcont` | Send MIDI continue |
+
+These ignore all parameters and send immediately.

+# Oddities
+
+Cagire's Forth is not a classic Forth. It borrows the core ideas (stack-based evaluation, postfix notation, word definitions) but adds modern features and domain-specific extensions. If you know traditional Forth, here are the differences.
+
+## Comments
+
+Classic Forth uses parentheses for comments:
+
+```forth
+( this is a comment )
+```
+
+Cagire uses double semicolons:
+
+```forth
+;; this is a comment
+```
+
+Everything after `;;` until the end of the line is ignored.
+
+## Quotations
+
+Classic Forth has no quotations. Code is not a value you can pass around.
+
+Cagire has first-class quotations using curly braces:
+
+```forth
+{ dup + }
+```
+
+This pushes a block of code onto the stack. You can store it, pass it to other words, and execute it later. Quotations enable conditionals, probability, and cycling.
+
+## Conditionals
+
+Classic Forth uses `IF ... ELSE ... THEN`:
+
+```forth
+x 0 > IF 1 ELSE -1 THEN
+```
+
+Cagire supports this syntax but also provides quotation-based conditionals:
+
+```forth
+{ 1 } { -1 } x 0 > ifelse
+```
+
+The words `?` and `!?` execute a quotation based on a condition:
+
+```forth
+{ "kick" s . } coin ?     ;; execute if coin is 1
+{ "snare" s . } coin !?   ;; execute if coin is 0
+```
+
+## Strings
+
+Classic Forth has limited string support. You print strings with `."`:
+
+```forth
+." Hello World"
+```
+
+Cagire has first-class strings:
+
+```forth
+"hello"
+```
+
+This pushes a string value onto the stack. Strings are used for sound names, sample names, and variable keys. You often do not need quotes at all. Any unrecognized word becomes a string automatically:
+
+```forth
+kick s .       ;; "kick" is not a word, so it becomes the string "kick"
+myweirdname    ;; pushes "myweirdname" onto the stack
+```
+
+This makes scripts cleaner. You only need quotes when the string contains spaces or conflicts with a real word.
+
+## Variables
+
+Classic Forth declares variables explicitly:
+
+```forth
+VARIABLE x
+10 x !
+x @
+```
+
+Cagire uses prefix syntax:
+
+```forth
+10 !x    ;; store 10 in x
+@x       ;; fetch x (returns 0 if undefined)
+```
+
+No declaration needed. Variables spring into existence when you store to them.
+
+## Floating Point
+
+Classic Forth (in its original form) has no floating point. Numbers are integers. Floating point was added later as an optional extension with separate words. Cagire has native floating point:
+
+```forth
+3.14159
+0.5 0.3 +    ;; 0.8
+```
+
+Integers and floats mix freely. Division always produces a float.
+
+## Loops
+
+Classic Forth has `DO ... LOOP`:
+
+```forth
+10 0 DO I . LOOP
+```
+
+Cagire uses a quotation-based loop with `times`:
+
+```forth
+4 { @i . } times    ;; prints 0 1 2 3
+```
+
+The loop counter is stored in the variable `i`, accessed with `@i`. This fits Cagire's style where control flow uses quotations.
+
+```forth
+4 { @i 4 / at hat s . } times    ;; hat at 0, 0.25, 0.5, 0.75
+4 { c4 @i + note sine s . } times ;; ascending notes
+```
+
+For generating sequences without side effects, use `..` or `gen`:
+
+```forth
+1 5 ..          ;; pushes 1 2 3 4 5
+{ dup * } 4 gen ;; pushes 0 1 4 9 (squares)
+```
+
+## The Command Register
+
+This is completely unique to Cagire. Traditional Forth programs print text. Cagire programs build sound commands.
+
+The command register accumulates a sound name and parameters:
+
+```forth
+"sine" sound    ;; set sound
+440 freq        ;; add parameter
+0.5 gain        ;; add parameter
+.               ;; emit and clear
+```
+
+Nothing is sent to the audio engine until you emit with `.`. This is unlike any classic Forth.
+
+## Context Words
+
+Cagire provides words that read the current sequencer state:
+
+```forth
+step    ;; current step index (0-127)
+beat    ;; current beat position
+iter    ;; pattern iteration count
+tempo   ;; current BPM
+phase   ;; position in bar (0-1)
+```
+
+These have no equivalent in classic Forth. They connect your script to the sequencer's timeline.
+
+## Probability
+
+Classic Forth is deterministic. Cagire has built-in randomness:
+
+```forth
+{ "snare" s . } 50 prob       ;; 50% chance
+{ "clap" s . } 0.25 chance    ;; 25% chance
+{ "hat" s . } often           ;; 75% chance
+{ "rim" s . } sometimes       ;; 50% chance
+{ "tom" s . } rarely          ;; 25% chance
+```
+
+These words take a quotation and execute it probabilistically.
+
+## Cycling
+
+Cagire has built-in support for cycling through values. Push values onto the stack, then select one based on pattern state:
+
+```forth
+60 64 67 3 cycle note
+```
+
+Each time the step runs, a different note is selected. The `3` tells `cycle` how many values to pick from.
+
+You can also use quotations if you need to execute code:
+
+```forth
+{ c4 note } { e4 note } { g4 note } 3 cycle
+```
+
+When the selected value is a quotation, it gets executed. When it is a plain value, it gets pushed onto the stack.
+
+Two cycling words exist:
+
+- `cycle` - selects based on `runs` (how many times this step has played)
+- `pcycle` - selects based on `iter` (how many times the pattern has looped)
+
+The difference between `cycle` and `pcycle` matters when patterns have different lengths. `cycle` counts per-step, `pcycle` counts per-pattern.
+
+## Polyphonic Parameters
+
+Parameter words like `note`, `freq`, and `gain` consume the entire stack. If you push multiple values before a param word, you get polyphony:
+
+```forth
+60 64 67 note sine s .    ;; emits 3 voices with notes 60, 64, 67
+```
+
+This works for any param and for the sound word itself:
+
+```forth
+440 880 freq sine tri s .    ;; 2 voices: sine at 440, tri at 880
+```
+
+When params have different lengths, shorter lists cycle:
+
+```forth
+60 64 67 note           ;; 3 notes
+0.5 1.0 gain            ;; 2 gains (cycles: 0.5, 1.0, 0.5)
+sine s .                ;; emits 3 voices
+```
+
+Polyphony multiplies with `at` deltas:
+
+```forth
+0 0.5 at                ;; 2 time points
+60 64 note              ;; 2 notes
+sine s .                ;; emits 4 voices (2 notes × 2 times)
+```
+
+## Summary
+
+Cagire's Forth is a domain-specific language for music. It keeps Forth's elegance (stack, postfix, definitions) but adapts it for live coding.

+# The Stack
+
+The stack is the heart of Forth. Every value you type goes onto the stack. Every word you call takes values from the stack and puts results back. There are no variables in the traditional sense, just this pile of values that grows and shrinks as your program runs.
+
+## Pushing Values
+
+When you type a number or a string, it goes on top of the stack:
+
+| Input | Stack (top on right) |
+|-------|---------------------|
+| `3` | `3` |
+| `4` | `3 4` |
+| `5` | `3 4 5` |
+
+The stack grows to the right. The rightmost value is the top.
+
+## Words Consume and Produce
+
+Words take values from the top and push results back. The `+` word pops two numbers and pushes their sum:
+
+| Input | Stack |
+|-------|-------|
+| `3` | `3` |
+| `4` | `3 4` |
+| `+` | `7` |
+
+This is why Forth uses postfix notation: operands come first, then the operator.
+
+## Stack Notation
+
+Documentation describes what words do using stack effect notation:
+
+```
+( before -- after )
+```
+
+The word `+` has the effect `( a b -- sum )`. It takes two values and leaves one.
+The word `dup` has the effect `( a -- a a )`. It takes one value and leaves two.
+
+## Thinking in Stack
+
+The key to Forth is learning to visualize the stack as you write. Consider this program:
+
+| Input | Stack | What happens |
+|-------|-------|--------------|
+| `3` | `3` | Push 3 |
+| `4` | `3 4` | Push 4 |
+| `+` | `7` | Add them |
+| `2` | `7 2` | Push 2 |
+| `*` | `14` | Multiply |
+
+This computes `(3 + 4) * 2`. The parentheses are implicit in the order of operations. You can use line breaks and white spaces to keep organized, and the editor will also show the stack at each step for you if you ask it nicely :)
+
+## Rearranging Values
+
+Sometimes you need values in a different order. Stack manipulation words like `dup`, `swap`, `drop`, and `over` let you shuffle things around. You will find them in the dictionary. Here is a common pattern. You want to use a value twice:
+
+| Input | Stack |
+|-------|-------|
+| `3` | `3` |
+| `dup` | `3 3` |
+| `+` | `6` |
+
+The word `dup` duplicates the top, so `3 dup +` doubles the number.
+
+Another pattern. You have two values but need them swapped:
+
+| Input | Stack |
+|-------|-------|
+| `3` | `3` |
+| `4` | `3 4` |
+| `swap` | `4 3` |
+| `-` | `1` |
+
+Without `swap`, `3 4 -` would compute `3 - 4 = -1`. With `swap`, you get `4 - 3 = 1`.
+
+## Stack Errors
+
+Two things can go wrong with the stack:
+
+* **Stack underflow** happens when a word needs more values than the stack has. If you write `+` with only one number on the stack, there is nothing to add. The script stops with an error.
+
+```forth
+3 +    ;; error: stack underflow
+```
+
+The fix is simple: make sure you push enough values before calling a word. Check the stack effect in the dictionary if you are unsure.
+
+* **Stack overflow** is the opposite: too many values left on the stack. This is less critical but indicates sloppy code. If your script leaves unused values behind, you probably made a mistake somewhere.
+
+```forth
+3 4 5 + .    ;; plays a sound, but 3 is still on the stack
+```
+
+The `3` was never used. Either it should not be there, or you forgot a word that consumes it.

+# Stage / Commit
+
+Cagire requires you to `stage` changes you wish to make to the playback state and then `commit` it. It is way more simple than it seems. For instance, you mark pattern `04` and `05` to start playing, and _then_ you send the order to start the playback (`commit`). The same goes for stopping patterns. You mark which pattern to stop (`stage`) and then you give the order to stop them (`commit`). Why is staging useful? Here are some reasons why this design choice was made:
+
+- **To apply multiple changes**: Queue several patterns to start/stop, commit them together.
+- **To get clean timing**: All changes happen on beat/bar boundaries.
+- **To help with live performance**: Prepare the next section without affecting current playback.
+
+Staging is an essential feature to understand to be effective when doing live performances:
+
+1. Open the **Patterns** view (`Ctrl+Up` from sequencer)
+2. Navigate to a pattern you wish to change/play
+3. Press `Space` to stage it. The pending change is going to be displayed:
+   - `+` (staged to play) 
+   - `-` (staged to stop)
+4. Repeat for other patterns you want to change
+5. Press `c` to commit all changes
+6. Or press `Esc` to cancel
+
+A pattern might not start immediately depending on the sync mode you have chosen. It might wait for the next beat/bar boundary.
+
+## Status Indicators
+
+| Indicator | Meaning |
+|-----------|---------|
+| `>` | Currently playing |
+| `+` | Staged to play |
+| `-` | Staged to stop |
+
+A pattern can show both `>` (playing) and `-` (staged to stop).
+
+## Quantization
+
+Committed changes don't execute immediately. They wait for a quantization boundary:
+
+| Setting | Behavior |
+|---------|----------|
+| Immediate | Next sequencer tick |
+| Beat | Next beat |
+| 1 Bar | Next bar (default) |
+| 2/4/8 Bars | Next 2, 4, or 8-bar boundary |
+
+Edit quantization in pattern properties (press `e` on a pattern).
+
+## Sync Mode
+
+When a pattern starts, its playback position depends on sync mode:
+
+- **Reset**: Always start at step 0
+- **Phase-Lock**: Start at the current beat-aligned position (stays in sync with other patterns)

+Live coding is a technique where a programmer writes code in real-time in front of an audience. It is a way to experiment with code, to share things and thoughts openly, to express yourself through code. It can be technical, poetical, weird, preferably all at once. Live coding can be used to create music, visual art, and other forms of media. Learn more about live coding on [https://toplap.org](https://toplap.org) or [https://livecoding.fr](https://livecoding.fr). Live coding is an autotelic activity: it is an activity that is intrinsically rewarding, and the act of doing it is its own reward. There are no errors, only fun.
