Microsoft Software Synthesizer

The Microsoft Software Synthesizer is supplied with DirectMusic and is the default port when hardware DLS is not available or is not supported by the operating system. The synthesizer creates a waveform based on a stream of MIDI messages, using instrument timbres synthesized from DLS samples. By default, the samples are from the Roland GS collection, which is also part of the DirectMusic installation. The synthesizer sends its output to the DirectSound mixer.

Note  The Roland GM/GS Sound Set cannot be modified. See the Copyright Warning for the legal restrictions.

The Microsoft Software Synthesizer includes reverberation capabilities, which are on by default. The Waves TrueVerb reverberation technology is licensed to Microsoft as the SimpleVerb implementation.
