Yeah, that's spam alright. Looks like it's time for the MG crew to fire up the filtering...
As for the original question, though...have you thought about something like this: https://www.modulargrid.net/e/nonlinearcircuits-timbre-timbre That there is a pair of independent Buchla-style wavefolders, each with its own I/O and CV input. You could go with an EQ or some such, but something like these gives you a lot more latitude in terms of sound alteration/mangling...just a touch for a little ear candy, or go nutz to get something that would've scared Genesis P-Orridge! Even better, if you've got a stereo delay of some sort in there, you can feed some modulation signals to this module, then send the audio results on to the delay and have each repeat have a different timbral color! EQs and such are easy enough, but if you're in an environment where something of this sort can run and play, this seems like the way to go.
