I'm trying to make a program that will allow a user to use different SoundFonts to play using a Midi device. Right now I'm using functions in mmsystem.h to play audio from Window's default SoundFont, GM.dls. I was wondering if there is anyway to point it to another SoundFont. I was also wondering if mmsystem.h would be able to use .sf2 files. I know that .dls files are the MS standard but it would be nice to have the added functionality of using both .dls and .sf2. Thanks BB
