Cagire is a terminal-based step sequencer for live coding music. Each step in a pattern contains a **Forth** script that gets evaluated at the right time, producing sound and events. It ships with a self-contained audio engine — no external software needed.
Cagire is a terminal based step sequencer and live coding platform. Each step in a sequence is represented by a **Forth** script. It ships with a self-contained audio engine. No external software is needed, Cagire is a fully autonomous musical instrument that provides everything you need to perform.
### Examples
A filtered sawtooth with reverb:
```forth
saw sound 200 199 freq 400 lpf .8 lpq .3 verb .

### Features
- **Cagire's Forth**: a stack-based DSL specialized for live coding
- Concise and light syntax, every step is a short script. Forth has almost no syntax, only words and numbers.
- Nondeterminism: randomness, probabilities, patterns as first-class operations.
- **Cagire's Forth**: a stack-based language made for live coding
- Forth has almost no syntax, only words, numbers and spaces. Very easy to learn for beginners, quite deep for experienced programmers.
- Nondeterminism and generative: randomness, probabilities, patterns thought as first-class features.
- Quotations: code blocks `( ... )` that compose with probability, cycling, euclidean, and conditional words.
- User-defined words: extend the language on the fly with `:name ... ;` definitions.
- User-defined words: extend (or redefine) the language on the fly with `:name ... ;` definitions.
- Interactive documentation: built-in tutorials with runnable examples.
- **Audio engine** (powered by [Doux](https://doux.livecoding.fr)):
- Synthesis: classic waveforms (saw, pulse, tri, sine), additive, FM (2-op, 3 algorithms), additive synthesis, wavetables, 7-voice spread, Mutable Instruments Plaits models: modal, granular, waveshaping, chord, swarm, etc.
- Drum models: kick, snare, hat, tom, rim, cowbell, cymbal with timbral morphing.
- Sampling: disk-loaded samples with slicing, pitch tracking, wavetable mode, and live recording from engine output or line input.
- Filters: biquad LP/HP/BP and ladder filters, each with independent envelope.
- Drum models: seven drum models with timbral morphing.
- Sampling: disk-loaded samples with slicing, looping, pitch tracking, wavetable mode, and live recording from engine output or line input.
- Filters: biquad LP/HP/BP and ladder filters, each with independent envelope. Filters can be modulated, stacked, etc.
- Effects: phaser, flanger, chorus, smear, distortion, wavefolder, wavewrapper, bitcrusher, sample-rate reduction, 3-band EQ, tilt EQ, Haas stereo.
- Bus effects: delay (standard, ping-pong, tape, multitap), two reverb engines (Dattorro plate, Vital Space), comb filter, feedback delay with LFO, sidechain compressor.
- Modulation: vibrato, AM, ring mod, pitch envelope, FM envelope, glide — all with selectable LFO shapes (sine, tri, saw, square, sample & hold).
