I've built a few Atari Punk consoles, and want to embark on the APC and Baby 10 sequencer project too, but was wondering:

Is it possible to have two APCs in one unit, but with the option to sync the two together so they can both be controlled by CV?

Basically I want to be able to tune the two square waves to separate pitches, and use the Baby 10 to run both oscillators through the sequence for some Devo-esque sync sounds. I've never personally seen a project like it, and figured someone here can help me out.

Is it way too complicated? Am I confusing you guys with my horrendous way about explaining things? Confused

it is possible to control them both from a single cv source yes, you would want to use a simple voltage follower for this though. as for tuning them together i think you will find that this is altogether a different problem.
The apc doesnt track through octaves in the same way that a regular vco does, and its extremely unlikely that both of your APC's are going to trak in exactly the same way, given that the resistors you used arent going to be exactly the same, the capacitors may have fluctuation in their values also, VCO's (in general :p) have trimmer pots for tuning so that these variations in values can be overcome, the APC just isnt that advanced.
So in conclusion, yes you can do what you want...to a degree, but its not going to be as musical as you desire. Hope this helps.
