I've been in touch with Kontakt and various VI developers whose products operate in Kontakt and they all say it's a ProTools issue. I've also been in contact with Avid and they say it's a developer issue since not every VI suffers stuck notes.

So, without anyone taking this on, it doesn't make much progress. The biggest offender for me currently is Arcade from Output. In simple sessions MIDI behaves but as MIDI content grows notes begin getting stuck, and the newest updates to Arcade lack the easy-to-find "reset" button which stopped playback when there was a stuck note.

FWIW, there's a fix for Monark. I'll try to find the steps and post them here. It works and I've not had an issue with Monark since going through that process. Reaktor was also a major offender but had a fix where a support.ism is added to the plugin to help with all notes off.

I'm using the latest version of all software and still see the stuck notes, so there isn't much news.
