GAAAAAAAH, just when I thought everything was going to be all right...
Using Viena, I've been able to get the bank numbers for the presets. But when I input them into the Track Properties, they don't show! I've moved the relevant sound fonts up and down, enabled and disabled them in case they started out as disabled or I accidentally disabled them during the first test, double-checked and retried the bank numbers, and nothing!
The numbers I've gotten from these sound fonts (which I downloaded from here in case you're interested. and yes, I decompressed them first):
000:000
000:052
I've been told that the first half of these numbers signify the program and the second half the bank, which contradicts what the QWS article about Bank Selection said about MSB/LSBs, but these were people on the QWS mailing list and they've been doing this a lot longer than I have.
I've honestly tried everything and I'm at my wit's end. I need help! What's the good of downloading all of these cool SF2s if I can't use them?!
