Strummed Acoustic/Picked Acoustic - Red Pattern Keys Not Triggering

am999

Hi, so it seems I can’t get the Session Guitarist patterns to play either by triggering the red keys via my MIDI keyboard or by clicking on the pattern name on the Patterns tab in the browser. No sound at all. All other sounds work just fine - all the yellow and blue keyswitches on the keyboard and any other link in the UI to any sort of sample work just fine. Same is true whether running Kontakt in standalone or DAW (Studio One 7) or on my Mac (M1 Airbook running Sequoia) or Windows 11. It’s been a while since I used the app so not sure when it broke. Additionally, it looks like the red keys are permanantly in latch mode even though latch mode is not on; i.e., when I click or play a red key, the note stays depressed. Any one have any ideas or have seen this behavior too?
