There are quad LFOs, EGs, and VCAs available. For a four input mixer there i=

ither a hyper minimoog or a limited 4-voice. Then the obvious enhancements o=
ccurred to me: 1) add 3 more VCF modules to dedicate 1 to each voice; 2) add=
 4 more VCO modules to allow sync modulation of the other 4 VCO modules; 3) m=
aybe simplify a bit and just use the PWM inputs on the original 4 VCO module=
s for timbre modulation rather than sync.

ack - in size, not to mention price). Looking around at other modules on the=
 market, I see the 2hp line which includes a couple of VCO modules (maybe ju=
st two revisions of the same product lineage). Since you really only hear th=
e quality of one VCO when two are synced together (well, unless you actually=
 mix both together, which can sound bad), I=E2=80=99m thinking that I don=E2=
=80=99t really need a full-size, transistor-only AJH Synth VCO for the secon=
d set of 4 VCO modules. Pairing a 2hp VCO and an AJH Synth VCO takes much le=
ss space for a 2-VCO sync pair.

CF is quite handy, with its minimoog-style 3-input mixer, but that only save=
s me a module if I operate in paraphonic mode, and even then it only handles=
 3 voices. The Rebel Technology Mix 04 and the Synthrotek MST Unity Gain Mix=
er look like fairly compact modules for combining the 4 voices.

 building a 4-voice modular is a crazy idea, so I=E2=80=99m here to ask what=
 experience folks have to trying something insane like this.
