Editing midi notes with the mouse is a pain.
You could use Atoms Encoders for editing midi notes:
- Encoder 1: select note
- Encoder 2: move note start by quantize
- Encoder 3: move note end by quantize
- Encoder 4: set note start in millis
- Encoder 5: set note end in millis
- Encoder 6: set note key
- Encoder 7: set velocity
- Encoder 8: set quantize
Mouses aren't music instruments!
