program against EVDEV, simple input event layer presents events as byte triplets. modprobe -ra keydev mousedev; modprobe -a evdev cat /dev/input/event* > my_app this is how GDAM supports USB touchpads, joysticks, keyboards, pen tablets, powermate big knob, etc. A USB mini keyboard, 120+ temporary on buttons for $12, is by far the cheapest control device. Treating it as a dedicated device with direct app support (as opposed to normal keyboard operating hotkeys) lets the controls stay the same regardless of window focus. But touchpads generally don't support pressure, so it doesn't seem to offer anything for drum triggering other than "zero travel time" vs. a keyboard. -geoff
