Channel Specific Settings
 
The M-Audio GM Module has 16 individual channels that correspond to the 16 channels defined in the MIDI specification  All 16 
channels of GM Module can simultaneously produce sounds  Each of these channels can be set to a different instrument and has its 
own Volume, Pan, Tone, Category/Instrument, Chorus, Reverb, Mute and Solo controls  The displayed controls always only affect the 
selected channel  
Channels 1-16
To select a channel, click on its level meter located above the channel’s number * The selected channel will appear with an 
outline around its level meter  The set of controls to the right of the channel meter display will only affect the selected channel  
The General MIDI standard provides for 16 MIDI channels, 15 of them with the same set of 128 available instruments  
Channel 10 is an exception and plays a special role since this channel is always mapped to the General MIDI drum kit  This 
assignment is fixed and cannot be changed  
  
 *Important: Clicking the level meter of a channel selects that channel for editing and allows you to change its sound 
patch, reverb level, chorus level, volume, and pan settings. 
However, selecting a channel in the GM Module software does NOT mean that KeyStudio will trigger instruments on that 
channel. To do that, you need to change the MIDI transmission channel on the KeyStudio 49i hardware to the corresponding 
MIDI channel. 
Example: To play the GM drum kit located on channel 10 of GM Module, change the MIDI transmission channel on 
KeyStudio 49i to MIDI channel 10 (see chapter 16 for details). To alter the drum kit’s settings, click on level meter 10 in the 
GM Module software, then move the on-screen controls to alter parameters like reverb or chorus level, drum kit volume, etc. 
M (Mute)
 This is the GM channel mute for a selected channel  The level meters of muted channels appear in a lighter shade of gray and 
will not show any meter activity – even if MIDI messages are received on this channel  A muted channel does not output any 
sound  
S (Solo)
 This is the GM channel solo for a selected channel  Soloing a channel will mute all other 15 channels of the M-Audio GM 
Module software  Accordingly, all channels with exception of the Soloed channel will be displayed in a lighter shade of gray 
and will not show any meter activity – even if MIDI messages are received on these channels  Only the Soloed channel will 
output sound while all other channels will remain silent 
 
 Note: If the GM Module is set to program zero in standalone mode so the KeyStudio 49i piano sound is heard, pressing 
Solo on a different channel on the GM Module does not mute the KeyStudio 49i built-in piano sound.
