Midi problems with PT 2022.12

[shobud10]

Hi All,
I've recently taken the plunge and upgraded from PT9 to 2022.

Since then I've had issues with recorded midi on instrument tracks. I have no issues when recording, using any VI, but playback is a different matter.

Sometimes it plays, sometimes it doesn't. Usually the first play after the session is open. Then, in order to hear the VI, I have to move the plugin to a different insert slot. Which will work for one play only.

I know sometimes PT loses the 'connection' to the VI when looking at the Instrument portion of the track, but this is not the case here.

The midi is always present on the instrument track, it just doesn't trigger the VI. Track meter shows no output.

It also doesn't matter what buffer size I use.

On Win 10 with a very capable PC.

I have a case open with Avid but they have ghosted me it seems. No reply for more than a week.

Interface is an 003 (yeah, I know it's old)

Has anyone had the same issue?
