1. Ability to trigger a clip in ableton on a given chord. Above each chord you could press advanced mode or something, and a square comes into view above the chords where you can assign the necessary cc message/midi learn thing(?).(not shure about the technicality, best way to do this....)
2. A stop button. My problem is remembering to hit sustain button again to continue playing chords after a break in an arrangement. For my use its practical that sustain is always on.
3. Imagine if you could trigger an inversion(s) of the chord you are on in the sequence. This would humanise it further. On a dedicated button.
4.Make a setlist of songs that you can move through with your feet.
5. This app on a mac. I know it might come true as Apple is working on it....
