I have been away from BIAB for a couple of years so I wonder if something has changed. I am using 2023.
My Roland SD50 does not change to a different midi patch even though the track title says I have changed. I don't think it is a synth problem because when I change songs each track plays the correct midi sound but they seem to be frozen regardles of how I change the patch by right clicking and selecting a new patch.
I did a search and there are past references to HI-Q patches but I have never knowingly used HiQ.
Thanks
Tony
