My needs as a drummer, however, do not require all of those inputs, so my question is...
Is there a way to make a simpler version of MegaDrum? one that takes say 5 inputs max?
I don't know the logistics of it all, I've never built a circuit board before, so... I'm pretty much in the dark

basically what I want to build is a practice Tenor Pad, aka marching quads/quints, so I have no need for the 32+ inputs and things.
Any thoughts and comments are immensely appreciated!!!
