Right, that boolean makes its way to the function I check,
Instrument::IsPercussion().

I got qsynth when you mentioned it before, but when it didn't work for me
immediately, I decided to spend the time on debugging instead. I will
give it another go.

I will.
But there's another aspect that worries me: Presumably we want older cards
like mine to work right too, and they still think 10=percussion. If you
give them percussion on another channel, they won't play percussion, bank
change or no. That's why I seem to be focusing on fixed vs. automatic
channels.
Now the auto logic could support both ways, by being smarter about whether
10=percussion. That implies we'd need to distinguish whether a device
assumes 10=percussion or does percussion by banks (possibly derived from
other information like a GM/GM2 setting).
Using such a flag or enum is easy, getting it is not. I could add to the
device setup dialog. But that'd mean new user-visible strings, and it
seems inconvenient to the user. And I don't understand the types of MIDI
device well enough to do it right. I suppose I could put a temporary
checkbox in the MIDI device dialog for testing, but it wouldn't be a
long-term solution.
