there are a few quirks.
foremost I’d like to see stuff u dont have a workaround.
for example: pads had some complaints (responsiveness) but u can hook up another pad controller easily.
- more analog machines (exploit that nice hardware!)
- sample based machines
- more modulation per track. better envelope solution. 2nd LFO
- more fx per track: eq, dsp stuff, …
- sequencer frenzy, ideas like: record pattern juggling to a new pattern, set inner-loops (lock Scale params in Scene)
and a ferrari for christmas 
what would you prefer to see?
