This is a side effect of one of my attempts to get MIDI out working from
the modular (by encoding the MIDI signal over the audio outs and then
decoding it with some DSP software).

The constant module is the input, the Serial Clock on the top is the baud
rate( I think thats teh right term ?), works at about 2.5kHz. Uses one
negative pulse for synchronisation.

I uses some very funky timing so the ordering of the modules is important,
but there arranged in such a was so that if you cut and paste them into a
patch the ordering will be right, which is how I got it right in the first
place. The paste order goes down and then across, IIRC.

The problem with this approach is that 1) very slow update rate, 2)
its difficult to decode at 44.1kHs, espeacially as yet get DC offset
correction at several places in the chain which complicates things.
