[sdiy] Crumar Performer Version 2

[Dakota Melin]

Hi,

I have a copy that I downloaded recently if you want it, I think I'd have
to send it to you directly off list though?

Incidentally, I was searching for some info on a weird fault some days ago
for the Crumar and other instruments that use the TDA1008. Some notes
seemed to be triggering the octave below in addition to the note I was
actually playing.
If the busbar voltage set by the EO circuit is too high, that causes it. If
you follow the trim procedure it should sort it out.
