Arduino bassline generator
Always uses MIDI channel 1
Circuit is set up as:
- D8 : MIDI RX
- D9 : MIDI TX
- D10 (switch) : hold current riff
- D11 (LED) : beat clock
- D12 (sitch) : sync: external MIDI or internal
- A0 (10K pot) : tempo (when running internal clock)
- A2 (10K pot) : densitude (low = more silence)
- A3 (10K pot) : wiggleness (high = more variation in selected notes)
- A4 (5 notch voltage divider) : Scale (TBD...)
- A5 (5 notch voltage divider) : Rhythm Type (TBD..)
