# Oscillators

Control synthesis oscillator parameters for synth sounds.

## Frequency and Pitch

```forth
"sine" s 440 freq .      ( set frequency in Hz )
"saw" s 60 note .        ( set MIDI note )
"square" s 0.01 detune . ( slight detune )
"lead" s 12 coarse .     ( coarse tune in semitones )
"bass" s 0.1 glide .     ( portamento )
```

## Pulse Width

For pulse/square oscillators:

```forth
"pulse" s 0.3 pw .  ( narrow pulse )
"pulse" s 0.5 pw .  ( square wave )
```

## Stereo Spread

```forth
"pad" s 0.5 spread .  ( stereo spread amount )
```

## Harmonics and Timbre

For oscillators that support it (like mutable):

```forth
"mutable" s 4 harmonics .  ( harmonic content )
"mutable" s 0.5 timbre .   ( timbre control )
"mutable" s 0.3 morph .    ( morph parameter )
```

## Multiplier and Warp

```forth
"fm" s 2 mult .    ( frequency multiplier )
"wt" s 0.5 warp .  ( warp amount )
"wt" s 1 mirror .  ( mirror waveform )
```

## Sub Oscillator

```forth
"bass" s 0.5 sub .     ( sub oscillator level )
"bass" s 2 suboct .    ( sub octave down )
"bass" s 1 subwave .   ( sub waveform )
```
