[sdiy] Midi2cv Project Update

Well, some good news for a change. My little midi2cv
board is putting out signals on all 8 mux channels,
and doing it using timer interrupts. No small feat,
let me tell you. Getting the IRQs to operate involved
finding an obscure app note from Motorola which sed I
had to clear a status register, one which comes up
cleared on reset, but has to be cleared anyway.

Despite that and random visits from ex-wife, the thing
is working. Not for the trivial task of reading,
decoding, and applying midi messages. Piece of pie!
