Arpeggiator based on Arduino and the SparkFun midi shield. Credit to wbajzek's arduino-arpeggiator for the foundation. It will run free or sync to midi clock if it detects a start message.
Button D2 = Toggle hold-mode on/off (I might replace hold-mode on/off with an octave button, since I will probably always use it in hold mode.)
Button D3 = Cycle through arpeggio modes
Button D4 = Stop arpeggio
Pot A1 = Tempo (With midi sync, controls the beat divisions)
Pot A2 = Velocity
Arpeggio modes:
- Up
- Down
- Bounce (e.g., 1-2-3-2)
- UpDown (e.g., 1-2-3-3-2-1)
- OneThree (e.g., 1-3-2-4-3-5-4)
- OneThreeEven (e.g., 1-3-2-4-3-5)
