The advanced controls like the VFader are a great way to add complex functionality to the small screen of the Mini. Some suggestions for additional controls:
- 2 dials/faders → eg for tune + finetune; volume + pan
- 2 buttons (on mkI/II: aligned left/right, on Mini: aligned top/bottom)
- 4 buttons in a 2 x 2 grid (for the Mini only)
Those would help me create a proper Ableton mixer for the Mini.
