In regards to the pad size/shape, we looked at everything out there, from piano keys to guitar frets to MPC pads, and everything else, and we looked at how lots of different people play. Where we aimed for is big enough to play drums with two fingers, small enough to play melodies. Calipers were used, and fat fingers, and skinny fingers. I am really happy with where we got to (yeah, biased, I know).
How do the pads compare to Maschine MkII. They're the most sensitive I've played so far.
Are the values the pad produces immediately converted to a 0-127 range in the hardware? Or would there be a way to get a 0.-1. float range?
