Halion 7 as VST external Param

I’m controlling the Halion remotely and receiving the following parameters: S1-s64, including: S1 Mute; S1 Solo; S1 Volume; S1 Pan; S1 Program Change; S1 QC to QC10.

What does Program Change mean?

What do QC 1 to 10 mean?

Thanks

Program change is basically the top level parameter. If you’re playing program number 12 which was a Violin, changing the program number to 17 might be a patch that is a Viola.

QC could possibly refer to “Quick Control” numbers 1 through 10.

ok thanks
