GM Module Standalone Operation with KeyStudio 49i

When configured for standalone use, the KeyStudio keyboard is connected to the computer, and the GM Module software is 
launched independently of any recording application  With this setup, the software automatically receives MIDI messages from 
your KeyStudio USB keyboard  All sounds generated by the GM Module software will automatically be routed to the two 1/4” audio 
outputs on the KeyStudio 49i keyboard  In most cases, MIDI input or audio output selection and configuration is not necessary *

 *Note: 

To optimize performance in Windows, you may wish to adjust the buffer setting within the KeyStudio 49i software 

Control Panel.  Please see the KeyStudio 49i Software Audio Control Panel section of this User Guide for more information 
on this.

When the M-Audio GM Module software is launched in standalone mode, it sends a MIDI message to the KeyStudio keyboard  This 
message programs the Octave buttons on KeyStudio 49i to send program change messages  The GM Module software always 
opens with program zero selected on GM Module channel 1  This mutes GM Module, allowing only the KeyStudio 49i built-in piano 
sound to be heard  Pushing the Octave “>” button unmutes GM Module, and allows you to step through program numbers 1-127, 
which trigger General MIDI sounds in the GM Module software (see the User Guide Appendix A)  The built-in piano sound in 
KeyStudio 49i will remain silent while playing any of the GM Module sounds when the software is in standalone mode   If program 
zero is once again selected on GM Module channel 1, the GM Module software will once again be muted, and the KeyStudio 49i 
built-in piano sound will be heard

transmission channel in order to control any M-Audio GM Module channel.
