Thanks for all the great suggestions everyone. I will do some further research.

@zuggamasta -- I have seen the Zlob SVF in your videos. Yes. :)

@farkas -- I actually bought a second hand Doepfer Wasp, but it arrived not working properly so perhaps you are right about its flakiness.

@GarfieldModular (or anyone) what's the difference between the OptoMix and the LxD? Just the Damp control? (Which is a slew limiter, right?) These are interesting but lack of resonance control seems a loss.

Anyone tried the WMD C4RBN? (or whatever it is called). Its tiny buttons put me off, but the demos sounds decent.
