well you didn't burst my bubble but I think if you wanted to take an extra amount of time for not much you could do the audio and key/pot with multiple pokeys, and with the one after the other you could tweak a parameter and then set it, and with the qwerty I saw somewhere a guy took the circuit board and fitted musical keys but it still probably is a whole lotta work for a whole lotta nothing! ::) oh and a quick unrelated question, has somebody made a midibox 64 keyboard? I think it would be fun to incorporate those into a lot of midibox synths! and NILS did you say the only way to edit parameters on this thing is with switches (for the shift registers)?
