Matt Haines and I were just talking privately about synthesizing pseudo-digital 
waveforms by stepping through predefined voltages with a high frequency VCO. 
Reading this about the Prophet VS gave me a brainstorm that I thought I'd share 
...

Suppose you have an 8 step analog shift register connected to an 8 stage 
sequencer. The sequencer gets it's output for each step from the shift register 
stages. The sequencer is clocked from a high frequency VCO and it's output is 
your "digital" oscillator. 
Here's the neat part... You use 1 channel of a midi/cv converter. Hook the cv 
to the input of the shift register and the gate to the clock of the shifter 
register. Now you can program your waveforms via with 8 quick notes at 
different pitches!

I realize this has nothing to do with the way the VS gets or uses it's 
waveforms via MIDI :).

I'll have to try it one of these days.
