Jim's spot-on regarding the utilities. It's obvious that this was built according to "sexy module" standards...and you've figured out why we hammer so much on that! "One-patch wonders" are very much the sort of thing that Sexy Module Syndrome leads to!
OK...for starters, there's only two VCAs in here. And this thing needs LOADS of modulation to make it kick...but without adequate VCAs, you're not going to get those amazing, changing-while-played sounds. Here's how to paint yourself into that corner...see if this sounds familiar...
So, you've got two channels of audio being controlled by your Pitt VCAs. But on one channel, you want this pitch vibrato to also come up slowly as each note is played. Good luck with that!...coz it ain't happening in THIS rig. You'd need another VCA to get that level change + modulation increase. THIS is why we all repeat "You can't have enough VCAs"...because they're simple tools that SEEM boring, but which allow some astonishing things to be patched.
Step 1: OK, those Moogs need to go. Yeah, they're convenient there. They're also more expensive when you take them out of their powered cab and put them in yet another powered cab. And they're currently preventing you from adding the things this build needs.
Step 2: check Jim's "shopping list" above. In fact, spend a veritable BUTTLOAD of time researching those things. They're NOT "optional", as some new synthesists seem to think.
Step 3: how about some more FILTERS? You've got a Wasp and a Ripples...but nothing that really screws with audio hard. Note that I'm NOT counting the Roland Aira module here, as it's less of a module that fits IN a patch and much more akin to an effects device that goes at the END of the patch. Look into something that allows utterly weird routings, that has double filtering, maybe even a resonance path insert. All of those exist...and much more...and allow loads more timbral variety.
Step 4: you might consider a complex oscillator. The only sources here (and I'm not including the Moogs here...seriously, they don't belong in here!) are a Plaits and a Dreadbox Hysteria. Plaits is good, the Dreadbox VCO has quantizing...but nothing here can do really complex internal crossmodulation. And without more VCOs with which to do that, trying to sacrifice either VCO for that purpose won't sound all that good. Even if you just doubled the Plaits and Hysteria, that would be a huge improvement.
This build might look pretty full...but the truth is that it's got some way to go and some mistakes to correct. Not unsalvageable, tho...
