Overview
A dual-oscillator wavetable synthesizer firmware featuring 3D morphing across an 8×8×8 wave cube with thru-zero FM and multi-effect processing. Load custom wavetables via USB.
- view_in_ar 8×8×8 Wave Cube — 512 waveforms in a 3D morphable space
- waves Thru-Zero FM — Phase accumulator supports negative frequencies
- blur_on Trilinear Interpolation — Smooth morphing across X, Y, Z axes
- library_music Dual Oscillators — OSC A (Left) and OSC B (Right) with independent positions
- tune 5 Effect Modes — FM, Ring Mod, Bitcrush, Wavefold, Overdrive
- usb USB Wavetable Loading — Load custom waveforms from USB drive
Controls
Main Controls
| Warp (knob + CV) | Base frequency (V/Oct, 0V = C0 = 16.35Hz) |
|---|---|
| Blur (knob + CV) | Effect depth (mode-dependent) |
| Time (knob + CV) | X-axis morph position (0-7) |
| Reflect (knob + CV) | Y-axis morph position (0-7) |
| Atmosphere (knob + CV) | Z-axis morph position (0-7) |
| Mix (knob) | Unison detune spread (0-5%) |
| CV_MIX | VCA control (0V = unity, +V = boost, -V = attenuate) |
Shift + Knob Functions
| Shift + Warp | Osc B semitone offset (±24 semitones) |
|---|---|
| Shift + Blur | Effect mode select (5 modes) |
| Shift + Time | Sub A level (0-100%) |
| Shift + Reflect | Sub B level (0-100%) |
| Shift + Mix | Output volume trim (0-100%) |
Effect Modes
Select with Shift + Blur knob. Effect depth controlled by Blur knob + CV.
FM
Cross-modulation between oscillators
Ring Mod
Multiply A × B with wet/dry mix
Bitcrush
Bit depth + sample rate reduction
Wavefold
Wavefolding distortion
Overdrive
Warm saturation/distortion

4.wav (Z=3)
5.wav (Z=4)
6.wav (Z=5)
7.wav (Z=6)
8.wav (Z=7)
