IMHO 6 voice is better. You can stack two voices and have still
3-voice-polyphonic, or, for even more fatness, three voices and have
still two-voice-polyphonic left.
My self-made polyphonic has only 5 voices :-(

Hey, the normal stereo DIN cables have only *four* leads plus shield.
The shield is connected to one pin.
How about 9-pin D-Sub plugs? Cheap, sturdy, easy to solder, not much
bigger than a DIN plug.

I'm not interested in a polyphonic modular synth, since I already have a
self-made poly synth (not modular though). But (in the long run) I'm
interested in replacing the voice cards in my synth with designs without
rare (Curtis) parts. It's a different board layout of course: several
PCBs containing a synth voice (2*VCO, VCF, 2*VCA, 2*ADSR) instead of one
PCB containing all the VCOs, another with all VCFs and so on. I don't
want to re-wire the frame. But the circuits could be the same.
