I have a patcher with send~ loaded inside poly~ and receive~ on the same patcher as poly~. I noticed that when I mute poly~, the corresponding receive~ has a stuck buffer.
I've been using poly~ to dynamically load/unload patchers and save CPUs when the patchers can be muted. Send~/Receive~ has been working great in this dynamic scenarios, but saving CPUs won't be possible if muting poly~ causes some sound residues...
I attached a simple demonstration of this. Any comments would be appreciated!
