Try this again in the right section. Modified a factory PC4 program, so the knobs/sliders are functional.
4 layer mono saw program that shuts down the filter a bit and opens it back up with resonance upon a slow release. With a quick enough release you should not hear the effect.
For a much more radical response, lower the 'Adjust/Release' number near the bottom left of the amp. env. page.

Env.'s 1 and 2 could be used as templates to affect other things.

I'll also re-upload the two I had in the wrong section. Somewhat similar.
