Yeah, I just want an all-in-one box I can use with max/msp and my outboard samplers where the whole mixer maps concept is integrated with some pads.... I haven't used an mbseq yet, so it's all in my mind anyway. But I think a midibox drum trigger thing would be amazing! I would build one for home use for sure, and so if you need any help...... I know you have a trigger finger, and they're probably pretty cheap on the used market, but it might be cool to figure out a midibox pad solution that could be diy'd from the ground up. Although, the fsr's I've found seem to be pretty expensive and in short supply.
Did you (or anybody else) think about connecting force sensing resistors to an AIN board?
the drum layers idea sounds really cool btw.....
