I have successfully routed multiple MIDI tracks to different channels of one rack (not track) instance of HALion Sonic SE. When I play them back, their sound reflects the sound selected for the HALion Sonic "slot" number that matches the channel number I set that track to, which is good because that's exactly what I want them to do.
However, when I change the program of one MIDI track --whether in the track overview dropdown, or the sidebar dropdown, or even in the HALion Sonic interface itself --it changes not only the displayed program name of that one track I was actually modifying, but also the displayed program name of all the other tracks associated with that HALion Sonic rack instrument. Which is bad, because I don't want any of the others to change at all when I edit just one of them.
Even though it doesn't actually change the sound or the name of the programs as displayed in the instrument's slots view, I still find this incredibly annoying, because it appears to change them in the main project view. This makes it more difficult for me to tell them apart at a glance, and to tell which track is making which sound.
For instance, say, for instance, that I have a MIDI track routed to Channel 1, and Channel 1's program is "Cello Duo", and I have another MIDI track routed to Channel 2, and Channel 2's program is "Chamber Strings". I've noticed that if I change Channel 2 to "Bellperc strings", then everywhere that it once said that Channel 1 was "Cello Duo", it changes to "Bellperc strings" as well, even though it still sounds as "Cello Duo".
Is there something I'm missing that's causing the program information to be tethered? Is there a way for me to make it show the program name independently (and accurately)? It's not a real problem, since I can always just rename the MIDI tracks so I can tell them apart --it's just not convenient. I know I'm probably just doing something wrong, but I can't figure out what.
(After searching the Internet extensively for an explanation of this situation [and finding nothing], I did ask this question on the Steinberg forum, but I still have yet to receive any kind of acknowledgement there.)
