The following MIDI implementation chart details the MIDI controllers, functions, and System Exclusive messages that the freeware BASSMIDI SoundFont Compatible MIDI Synthesizer Driver for Windows supports. The BASSMIDI Driver utilizes Un4seen Developments' BASSMIDI Audio Library (BASSMIDI.dll) for it's SoundFont synthesis engine, hence the MIDI implementation chart is applicable for the BASSMIDI Audio Library (or any program that utilizes it) as well.

Note that all of the XGEdit 95 Compatible parameters shown in this image displayed in bright green are standard GM/GS MIDI controllers and System Exclusive messages, while all of the parameters shown in the image displayed in bright yellow are special XG MIDI controllers and System Exclusive messages directly referenced by this document.
