I never had to use this primitive yet, but it seems it could be a bad problem. I'm posting here since it seems a bug report was never posted, so if someone searches for a report (s)he can find it. Workaround is in the post above.
- "Is playing" primitive produces crash/lockups when connected to selector, host runs in multi cpu mode and loading more then 4 instances of this primitive. (so could be 2 instances of your vsti , if 2 of these primitives are in your vsti)
Crashes mostly when pressing play/stop often in host transport controls.
Also creates unstable behavior after deleting vsti in host and pressing play/stop some times after that (when muliple of your vsti still loaded) Happens in single and multi cpu host mode.
