Well to be honest I actually planned on using QBAS's code sending keypresses to the MK. Basically it's a cheap keybed to me, but I do wish I was about to trash something less rare :-\ Unfortunately I didn't get a cable, and haven't been able to track down so much as a pinout :( I don't know if these things are meant to be velocity sensitive or what, and I fear destroying a perfectly good velocity/aftertouch sensitive keyboard matrix decoder may be ahead of me :( If you have any info about these things it'd be great, or if you want to swap a similar board of lesser collector's value for it, just say the word and she's yours.
