MS4 (W11) - Custom Instruments do not appear in the mixer
I have a custom soundfont and instruments.xml file for our studio specializing in Middle Eastern percussion. I can see the soundfont as an option in the mixer, for example for the metronome, and my instruments are selectable from the instrument list, and the notes appear correctly. However the instruments don't appear in the mixer so I can apply the soundfont to them.
What does the mixer need to add these instruments? I've compared my xml to the instruments list and all appears to be in order. And these all worked fine in MS3, so I think I'm just missing something small.
Thanks for any help! MS4 looks fantastic!
