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. In DOS/Windows 3.1x, you must install the DOS AWEUTIL utility for the MIDI Emulation feature to function properly. For more information, refer to the AWEUTIL.TXT file in your audio software directory. Protected mode software does not support MIDI Emulation. You can still play music from such software by using the 4-operator synthesizer chip. Changing Audio Card Settings B-3

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.
In DOS/Windows 3.1x, you must install the DOS AWEUTIL
utility for the MIDI Emulation feature to function properly.
For
more information, refer to the AWEUTIL.TXT file in your
audio software directory.
Protected mode software does not support MIDI Emulation.
You can still play music from such software by using the
4-operator synthesizer chip.
