CONTROLLING THE SYSTEM MIX PLUS VCA
Before controlling the System Mix Plus VCA, you need to enable the VCA from the Expanders
category of Setup mode.
For each Ground Control Pro preset, you can assign a specific volume level, or you can control
the volume with expression pedals, or do both.
Controlling the VCA with Preset Volume Levels
Volume changes can be programmed for each preset. Press [SELECT
2] until you see the
display:
A value of “--” means no volume change will be sent when the preset is selected. Press and
hold the [DATA] buttons to enter a preset volume level from 00 (off) to 99 (maximum).
Controlling the VCA with Expression Pedals
To control the VCA with expression pedals, you set them up just like in “Using Expression
Pedals” below. Press [SELECT
2] until you get to the pedal display for the desired
Pedal (1 or 2):
Press [CURSOR
4] to select the target device. Then press [+/YES] to choose VCA.
The display should look like:
Now press [CURSOR
3] to return to the previous screen. Use [DATA] to select Stereo, Left,
Right, or Pan. The expression pedal now controls volume from 0 (off) to 127 (maximum).
Using Both Preset Level and Expression Pedals
You may use both the preset level and the expression pedals simultaneously. When a preset is
recalled, the preset level will be sent to the System Mix Plus. The expression pedal will override
the preset level only when the value of its position matches the value of the preset level. This
avoids any drastic volume changes when the pedal is moved.
For example, if the Preset Level is 99 (maximum volume), then the expression pedal won’t
take control of volume until it has reached its full on position. Then the volume will track the
movement of the expression pedal.
If the expression pedal is assigned to Left or Right, the preset level will control only the other
channel of the volume control. For example, if the expression pedal is assigned to the left
channel, then the preset level will control the right channel.
