Quad wavetable oscillator

Main structure (current)

4 oscillators: 1 main, 3 followers
Each oscillator: DC-coupled CV / audio input and a dedicated parameter pot
2 aux CV inputs
Shared waveform and bitcrush control (phase 1) can be decoupled per oscillator (phase 2)
3-position switch for page / octave selection:
- Quick left / right to change octave ,globally or per voice (phase 1)
- Left:
  - CV attenuation page (phase 1)
  - engine selection (phase 3)
- Right:
  - output attenuation (phase 1)
  - engine parameters (engine dependent)
  - wavetable selection (phase 3)
Mixed output — mono or stereo via jumper

Phase modulation (phase 1)
- Each input modulates phase of that voice; pots are tuning. Main offsets the others. Aux CV for reset.
Regular VCO (phase 2)
- Each oscillator input is V/oct; each pot is tuning.
Scale (phase 3)
- User picks a scale (fixed list for now; later from SD card config).
- Main sets the fundamental; other voices pick chord notes. Turning main effectively change the chord.
Binaural (phase 4)
- Detune / beating: main sets pitch for all followers; follower pots set beat frequency. Subtle but organic; beating pattern stays coherent when changing main pitch.

One wavetable (phase 1)
Two bitcrush modes:
- Synced (phase 1): distortion amount independent of pitch
- Free (phase 1): samplerate-reduction character — effect frequency interacts with signal frequency

User waveform import from SD card (phase 3)
Save / recall patches from SD card (phase 5)
LFO engine (phase 5)
Scale value update: free, on aux CV trigger, or via dynamic gate from CV inputs (phase 3)

Engine selection: per voice vs same engine for all voices — currently per voice; may limit workflow later.(phase 5)
If per voice engine: how to use aux CV inputs.(phase 5)
