Chris,
The DLS and SoundFont spec don't have a concept of these instrument
categories (as far as I know) as they're shown in the instrument
picker in QuickTime. It turns out that certain categories exist
for the General MIDI standard and the QuickTime instrument picker
simply categorizes according to the GM standard.
So, there's no way to query a MusicDevice for this info...

I would like to provide users with an NSBrowser to select
DLS synth instruments based on categories. I really just want the
default groupings for the Apple instruments as they appear in
the QuickTime instruments picker - Piano, Brass, Reed, Drum Kits, etc.
Is there a standard (MIDI or CoreAudio) way to determine this?
Using the AudioUnit properties I can get the ID and name of each
instrument but I do not see any obvious way to determine which belong
to which group. I could hard-code a scheme based on IDs or indices
but if there's a dynamic way to determine this at runtime I'd rather
use that...
Thanks for any help,
Chris
