processBlock no longer called after closing editor

Hi - strange one this. Everything is fine whilst the editor window is open - as soon as I close it, processBlock gets called for a few more bars and then stops. Starts being called again when I reopen the editor Window…

Any ideas? This is on Windows with Ableton Live - will try on OSX in the morning…

cheers

Strange isn’t the word! It could only be the host that is stopping the processBlock(). Did you try with another host on Windows?

No, but I’ll download something and try. Last night I built a new VST from scratch and made no changes to it and had the same issue with that, just to be sure it’s not something crazy I’m doing…

Same on OSX with Live…

Just tried in Reaper and not happening - so only appears to be happening in Live…

Looks like it’s a known issue:
