Seriously, if you want to do this, digital is the way to go. Roland had a
sequencer that worked this way back in the early eighties. Basically it
could be done with an AtoD into RAM then back out via a DtoA to play your
synth. Addressing could be handled by a counter. Battery backup on the RAM
would take care of holding the info between uses.

The obvious next step is to go to microcomputer. I had something similar
running with my roland back in '86, the only exception being I was scanning
my keyboard digitally rather than using an AtoD because the Roland
electronics had died.
