1 year ago - set keyboard rhythm volume to 0, midi out to ch10, pattern to something and turn it on
- handle any note-on for ch10 as triggers for arpeggio steps (rather than clock ticks)
- "learn" pattern in first beat (24 ticks) by determining steps based on there being any notes on during a tick (how we do know where the start of the beat is? only matters on non-even rhythms)
- this determines the number and duration of each step, then when notes are played, they are divided evenly between the steps, with extra notes on earlier steps as required
- this requires reading more note-on from midi_out (which currently just reads clock)
