[sdiy] crosspoints (was: What type of switch would this be?)

[Jeff Farr]

Well, that is exactly what I plan to do. The immediate purpose is to make a
modulation matrix for my OB-1 clone, but I am working to make the circuit
general enough to be easily moded into a module to control modular synths,
including 64 channels of CV (thanks to MidiBox).
