Here’s an idea : a while back, I made the XYPad (a Duplex application designed to take control of the native XYPad device). You can read about it here
So … how about “XY Pad + glide” - an extended XY pad which respond to higher pressure by moving faster towards the point being pressed - or slower, if less pressure is applied
Slow movements are normally quite hard to pull off on an XY pad, so it would seem uniquely suited to the QuNeo (but useful with other hardware as well, control the time factor using e.g. a fader)
