QT 5 incorporates support for both Sound Fonts and DLS.
Furthermore in OS X Core Audio provides a component that you can talk with
directly for Sound Font and DLS support. Its in the AudioToolbox framework
and its the DLSMusicDevice (which is an audio unit).
You can set a sound font file as a property of this unit, send MIDI messages
to it, etc. (That property is listed in the Audio Unit properties header and
it takes a FSSpec). You should set this property BEFORE you initialise the
synth (after you've opened it).
There's a "funky" version of how to use this in Java in
/Developer/Examples/Java/CoreAudio that is easily translated to C
(MIDIGraph) - we'll have some more examples available shortly (Yes - I know
I keep saying that.. its coming).
If you've got any questions on using this - just post them to this list.
