Yes, seems Noel solved that (thank you Noel) , but it was definitely not obvious from pop-up in Preferences.


"I've tested it with Halion sonic7 and now the problem is that I can't get it to respond to program changes"
Do you have "program changes" enabled in Sonic?

P.S. I was considering Sonic 7 when it came out and was beta testing for another audio software. We were able to populate GM instruments when MIDI composition called them out, but it would not do program changes. I use previous Sonic / Halion 6. Seems to work OK.
