WildMIDI is a simple software midi player which has a core softsynth library that can be use with other applications. The WildMIDI library uses Gravis Ultrasound patch files to convert MIDI files into audio which is them passed back to the calling application for further processing or output. The API of the library is designed so that it is easy to include WildMIDI into applications that wish to include MIDI file playback. With multiple MIDI file support you can develope applications to mix several midi files together at the same time and with the next release you will be able to use a different patch set for each MIDI file.
