Hi Noel,

Thank you for the feedback. I checked everything in your message and confirmed that everything lines up with your suggestions ie...

- Style = M_BZ128P.STY
- Piano track is blue (1799:Piano, Rhythm...)
- Piano Plugin is Plogue Art et Technologie...
- Update 818 is installed

The good news is that somehow it started working ie... I can now hear the Hi-Q piano playing (even though I haven't changed anything).

The ??? news is that still get a YELLOW pop up at the bottom right when I open BIAB with error message "Could not load Hi-Q Patch. BIAB instruments might not be installed."

I'm not sure how/why it has started working or why I'm still getting the error notification. If it stops working again I will check the things you've mentioned first.

Thanks,

Joe
