Well, don't discount the MS-20 Mini...if you add that 'nexus cab', it integrates wonderfully with the scalers and inverters. But even without it...well, gonna let you in on a little trade secret...
The MS-20's input section, for normally-pitched instruments, sucks. It mistracks, follows stronger harmonics, etc. BUT...there IS a way to use that to your advantage and get lots of squeally, crunchy percussives out of it. What you do there is to run a percussion source with indefinite pitches into it, patch and adjust the various bits...and VOILA: instant Aphex-style industrialoid acid-type weirdness! The Volca Beats is perfect for this, although my preference is (like Aphex) a TR-606. You just send the pitch-to-CV converter to the VCOs or filter cutoffs, the envelope follower to the filter cutoffs, trigger extraction to the trigger-in, and add some of the bandpass-filtered audio to the VCF. It's insane...and given that you can get a used MS-20 Mini for under $400 these days and an SQ-1 matching sequencer (matches the Volcas, too) for $100 new, its cheap and potent for the money! Put that against the 0-Coast, and you've got some serious sonic mayhem!
With a 606, it has to be heard to be believed...that box's cheezy 'chinnnng' cymbal turns into all sorts of metallics screeches and yowls, for example. Truly an endless source of rhythm processing, that synth.
