Hey @Justmat! This is a great script. I was reading through the documentation on greyhole on the sccode site and was wondering if you had played around with implementing a freeze function at any point. I’ve been missing that feature on a reverb since I sold my OTO BAM a while back. The docs say this:
A setting of 1.0 produces infinite sustain.
It seems like this could work if a single button set feedback to 1 and killed the input into the supercollider dsp.
