These chips use Soundfonts (SF2 files), that contain the wavetables (audio samples) for the various instruments. I am using these two MIDI drivers on Windows XP Professional 32 bit and Windows 7 Ultimate 64 bit:īoth drivers are installed as MME (MS Multimedia Extension) MIDI drivers, just like the standard MS GS Wavetable Synth.īoth use the BASS audio library, which contains a software synthesizer, that emulates the EMU sound chip of Creative Soundblaster audio cards (and compatible hardware).
