Hm, alright. I'm using this primarily to trigger a sampler so while velocity sensitivity WOULD be nice, it isn't a neccessity. It looks like I could use an extreeeemely simplified version of the midio128 design. I guess I've just gotta get figurin and see whats what. How tough would it be to add velocity sensitivity? I am looking to use pushbuttons of some sort a la most samplers, not actual keyboard style keys.
