Ok, didn’t get the envelope I thought I might be able to, the location circuit was just too slow, even with a high offset. I got something that sort of worked, but it took enough maths channels that would better serve as envelopes themselves.
However! Inspired by @mdoudoroff 's recent patch survey video, I patched up a nice w/ looping delay thing with logical audio mixing between my wet and dry signals, and feedback modulated by the survey knob and the follow circuit following the dry signal’s dynamics!!! Fed it a simple sequence and experienced lost time.
