Not so much...some of the VCOs are intended for AF-domain modulation of either VCAs or direct FM to other VCOs. I tend to do a lot of that...this one thing I just got done tracking on a few minutes ago (decompressing post-overdubbing!) has a massive amount of that going on, albeit in this case on an Arturia ARP 2600V (works about the same as the actual one I had, in fact...no major regrets there) using strange cross-modulations that eventually get out into a huge processing cascade, with the result (once I get up tomorrow and apply some band-selective filtering to it) that I have this perpetually-evolving sound wash that'll sound like moving through a forest by a stream, complete with intricate spatialization partly done with a Lorenz attractor device in MAX. Frickin' beautiful, in fact.
But sometimes, ya just got to have knobs and wires to grab onto...so something this, ah, expansive (or should that 'a' be an 'e'?) is what I'd feel comfortable with, particularly if the eventual plan is to get out and do more live work. And that IS the plan...eventually...
