Enabling/Disabling MPU-401 MIDI Emulation

The MPU-401 MIDI Emulation feature allows most real mode games, which do not support wavetable synthesis, to play wavetable music from the audio card. The MIDI output from the games is directed to the wavetable synthesizer rather than the MPU-401 interface. Games that have not been designed to use the wavetable synthesis features on your card can now use them.
