i don't know what to do: to sell my m3 for parts or try to repair
my m3 has the main bord klm-2642 out and this doesn't allow anymore to play pads, to be palyed by keybed but only by midi by a master and even the usb ports don't work with problems to load anything.
i have 2 questions: where to find parts new or used
2. if you know if by a pc editor could be solved the problem to load programs and combinations
thanks for help

Parts Is Parts has some parts available but I don't think they will have everything you need. It might be cheaper to buy a used module than to repair the one you have.

You can load PCG files using the editor but without USB it will be slow going over MIDI.
