Mute
The Mute button switches the volume of the channel between zero and the current
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 fader position (and value) is used.
If you want to mute a channel:
1 Click the Mute button of the desired channel.
2 Click the button again to reactivate the channel.
Pan
The Pan knob allows you to directly control the pan position of the sound.
To control the pan position of a sound:
1 Click-hold the Pan knob.
2 Move the mouse up and down. The knob moves according to the mouse position.
Note: Clicking a fader or knob while holding Option resets the value to a neutral value.
The neutral value is zero for all controls except Volume (#7) = 100, Panorama (#10),
Balance (#8), Resonance (#71), Release Time (#72), Attack Time (#73) and Cutoff
Frequency (#74)—all of which have a default value of 64 (center position).
Other Controllers
You can send any controller data—to control different parameters of your sound
source—with each of the upper rows of knobs.
Selecting Other Controllers
In the Track Mixer, you can simply click on the label above the knob to choose a
different controller. In the View > MIDI Track components menu you can determine the
number of controller knobs by choosing Assign 1–5. The default is set to two knobs.
In the Environment GM Mixer, use the text boxes on the left to choose different
controllers.
Here’s a description of the predefined General MIDI functions. Not all MIDI instruments
will understand these Controllers:
Reverb (Controller Number 91)
This knob controls the reverb level. The further right you turn the knob, the louder the
effect signal becomes (in other words, more signal from the channel is fed into the
effect processor).
Chorus Depth (Controller Number 93)
This knob controls the depth of the chorus effect. The further right you turn the knob,
the stronger the effect becomes.
