um.

I think perhaps a better way to do this, is instead of using 
sample-and-hold, is to simply use a cartridge with several trimpots (or 
resistors) to control the voltage for each stage. This would be _really_ 
simple... set the trimpots, once you have a sequence you like, keep the 
cart to use later, and build a new cart for a new sequence.. i think 
we're gonna build one of these for an analog sequencer already built.. 
just haven't had time..
