Is there a way to use custom soundfonts/soundbanks with winmm?

Question

Is there a way to use custom soundfonts/soundbanks while playing MIDI files with winmm.dll or do I have to use something else to do that? (I'm trying to do it in FASM).

Answer 1

The default synthesizer, "Microsoft GS Wavetable SW Synth", uses the file gm.dls, which is a system file and should not be replaced. There is no programmatic way to choose another sound font.
