There’s a few different behaviours.
When nothing is selected:
- Encoder 1 scrolls by +/- 1 vertically
- Encoder 2 scrolls by +/- 12 vertically
- 2ND + Main encoder scrolls through pages horizontally
- Main encoder scrolls by +/- 8 - think of it as ‘vertical pages’. That way you don’t miss any notes
- Up/Down arrows scroll by +/- 12 vertically
- Left/Right arrows scrolls through pages horizontally
When selection is active:
- Encoder 1 and Main encoder shift the selected notes by +/- 1 semitone AND scrolls +/-1 vertically
- 2ND + Main encoder is unavailable because 2ND shifts the selection mode
- Encoder 2 shift the selected notes +/- 12 semitones
- Up/Down arrows shift the selected notes by +/- 1 semitone but do not scroll in the piano roll
- Left/Right arrows shit the selected notes by +/- 1 step unit (1/16th note in zoom x1)
It might seem convoluted at first, but it’s flexible enough that you get to work out which workflow corks best for you.
