arduino_monotron
The code is for Arduino and is supposed to control a Korg Monotron via MIDI
Done:
- CV pitch tracking,
- Filter control,
- pseudo exponential ADSR,
- Legato, Portamento and normal mode,
- pitch bend,
- logarithmic scaling for adsr pots,
- LFO saw, ramp, square, triangle
- wavetable based LFO, with also waves for exp env to be implemented
- VCA,
- Different envelopes for VCA and VCF
- Different LFOs for VCA and VCF
- exp envelopes based on wavetable
- trigger lfo at gate on or continuous
- change lfo at zero crossing
- adsr changes at new stage to avoid glitches
Todo:
- add several modes for legato,
- lfo pitch tracking,
- Velocity,
- Add LFO and Env for pitch
- Upload schematics,
- code with functions written correctly,
- When in Legato, let the decay continue or it creates artifacts with short notes
- add a proper modulation matrix with several lfos and env going to different destinations
- random lfo
- make lfo affect + and - the wave and not only +
- save settings to EPROM and recall
- fix sound glitches, in some ENV settings
- build a proper case
- add a simple sequencer
- add a simple arpeggiator
- add an output buffer opamp
