While it is not quite what you asked (at least I think), at some point I've played around with some Akai MIDI controllers [1] of a friend of mine. I ended up using them as crude I/O devices for a Tetris-like game [2] and for simple animation tests [3]. Even ported it to WebMIDI, but hit some barriers in the amount of IO the drivers and link could handle. At some point I must have forgotten about this, so thanks for reminding me. I might also experiment with this again. :) Also sorry for the potato quality videos, it's the best I have at hand.
