> The USB-MIDI data rate limitations are clearly visible when trying to change the state of 64 keypads at once. 64 individual signals with 8ms latency completely break the flow[2], compared to a single optimized OSC message. Can't agree enough. I picked up a Launchpad since it was cheap and looked fun to hack on. I wrote a Python module to talk to it and then watched it chugging along while writing a sequencer on it; the bandwidth just isn't there to do intelligent updating of the pads. It is a fun little device, though, and I can't wait to get my Push to continue the work (the protocol seems to be more sane, given what Ableton is doing with it)
