I am having trouble with Pianoteq 9 glitching out when I play too many notes, and am in the middle of troubleshooting it. I recently upgraded it, I did not run into this issue with Pianoteq 7 or 8

True! But this was not a “serious” gig. It was a “testing” gig. More of a VWAP actually… (Very well attended practice/bar gig). I won’t make any changes before a wedding or corporate gig :slight_smile: I’ve been using GP for four years for keys and guitar and its been super reliable. Unrelated: …
