Updated my schematic with these additions, thanks @blah !
- Replaced LFO Enable and Ampitude Mod with switches, not sure if these will work on a multiplexer connected to an analog pin.
- Added second Arduino for Poly mode based on juha’s code and @soldierperil 's picture, thanks!
- Connected each multiplexer’s Enable pin to ground.
- Removed Algorithm Switch 1 and 2 from the main Adruino because the code just says “Algorithm ??”
- Added Algorithm Switch 1 and 2 to the Poly Arduino, i think these are the unlabelled toggle switches on the front panel of LMNC’s machine.
I haven’t added any additional controls yet, trying to get it to the stage LMNC has it.
Does this make sense?
