AW: Wanna build an analog CV harmonizer?

Very good idea. Would be similar to an arpeggiator in random
mode, only that you don't need a polyphonic keyboard, but store
the last few notes instead.

I am thinking of a similar thing since a while: I *have* several
CVs from a polyphonic keyboard, and I want to add a hardware-
based arpeggiator. Might be easy with a little sequencer circuit
( CMOS 4017 etc.), and an AND gate between the keyboard's
gates and the ADSR's. Problems occur if you have pressed less
then all available notes. Either you'd get rests, or you have to add
some logic to skip the sequencer until in gets to a position that
corresponds to a note-on from the keyboard.
In Your idea, you would always have random picks from a fixed
number of recent notes. This is surely an interesting option, but
care must be taken if you make chord progressions and some
recent notes won't fit in anymore. (Which might be interesting
also, of course.)
