I have a B-MonoPoly. I know it's not a module (and it's Behringer), but it's controllable via CV (along with all sorts of I/O: CV, MIDI, ETC). 4 oscillators and lots of other goodies (modulation-wise). It would inject a more "traditional" synth voice into your setup. It's also built very solidly, which I consider a real plus in this world of plastic-y crap.

It’s actually looking pretty good for a Behringer! For the more traditional sound, I have the CEM3340 based bOSC in there. That chip was used in the Prophet 5 and others and it's pretty great actually! I'm using it with FM in my track of yesterday on Soundcloud
