Adjusting the Level of a Channel
The Level fader controls the output level of a MIDI channel. Adjusting it sends
controller 7 via your MIDI interface.
To adjust the output level of a channel:
m Drag the Level fader up or down.
Muting a Channel
The Mute button switches the volume of the channel between zero and the current
Level fader position. In practice, this means that if the button is down, the channel is
muted. If you switch the Mute button off, the current Level fader position (and value) is
used.
To mute or unmute a channel:
m Click the Mute button of the desired channel.
Assigning the Knobs to Controllers
You can assign any controller to each of the knobs.
To assign a controller to one of the knobs:
1 Click on the label next to the knob.
2 Choose the desired controller from the menu.
Extended GM, GS, and XG Functions
In addition to the GM Standard, there are extended standards created by Roland (GS)
and Yamaha (XG).
GS and XG mode allow you to select different effect programs, and to control the level
of the reverb and chorus effects.
To display the GS or XG effects:
m Choose the GS or XG setting in the menu in the mixer’s lower right corner.
The GS/XG configuration control is displayed on the right side of the Mixer, allowing
you to select different effect programs.
To configure GS or XG effects:
1 Choose the desired standard in the first menu.
Depending on your selection, the controllers for the extended effects will appear.
2 Select the desired reverb or chorus effect from the second menu.
3 Program the desired reverb or delay time (Time parameter).
Resetting All Controllers
The Reset button transmits a GS On or XG On command, and resets all controllers to
neutral positions. This allows you to reset all connected sound modules to their
standard settings, and begin a mix from scratch.
