This just started happening this weekend (August 12, 2023). I load a VST Instrument and start playing it, and then it randomly unloads while I’m playing. I’ve never had this issue in the past. It appears to have happened after the most recent Windows update (mid August).

This is an example VST piano plug-in. I’ve tried it with other VSTs as well, it doesn’t matter. I’ll drag a VST her to load it. Then I’ll start playing and after several seconds of playing it just disappears.
Martin - Where I have the arrow pointing in the above screenshot just disappears while I’m playing, and of course, the sound from the VST stops. It’s a behavior I’ve never seen before this weekend.
Here’s the before and after. As you can see the before has the MIDI track assigned to the VST (TruePianos) and all is fine.
I start playing my midi keyboard … not even running the recorded track, just playing the VST from my midi keyboard. Then after a few seconds, the VST disappears and the MIDI track’s assignment says “Missing”, and this time, the cycle button activated on its own!
I think this issue is indeed related to the midi keyboard. Something got corrupted it appears and it was sending various commands, depending on what keys I was playing. After rebooting the midi keyboard, it appears to be okay. I’m going to keep playing to make sure that I’m back to normal here. I appreciate all of the help! Thanks again!
I use an Arturia KeyLab 61 MKII connected by USB. I’ve had it for a few years, it’s great and I’ve never had an issue with it until today, but after rebooting it, it’s working fine now.
