I recently dug an old Hott-Lixx toy guitar out of storage, and I though it might be fun to build a basic midibox64 into it. Here's a picture of one: I was thinking a CORE and a DIN module would be all thats needed. There's only one knob, maybe a rotary encoder for program changes or somethin'. The rest of the toy is covered in buttons, which I'm hoping still work. I was thinking of using this to control a software sampler. Anyway, I guess I don't have any specific questions, I was just wondering if anyone had any other ideas (for expansion, changes, features...). An LCD perhaps? Any suggestions would be most appreciated.
