130 Chapter 6 Working in the Mixer
To set the physical output channel for an output in the Mixer:
m In the channel strip for the output, choose the physical output channel, or pair of
channels, from the Output pop-up menu.
Note: You can create outputs independently of the audio hardware connected to your
computer, and route audio to an output that does not correspond to a physical output.
In most situations, each output in a project should correspond to a physical output on
the audio interface or other hardware connected to your computer. Outputs that do
not correspond to a physical output will not be heard. You may set as many outputs in
a project to the same physical output device or output channel as you like.
Muting and Soloing Channel Strips
You can mute and solo channel strips in the Mixer in order to hear or silence specific
tracks, busses, or outputs.
To mute a channel strip:
m Click the channel strip’s Mute button. Click the button again to unmute the channel
strip.
To solo a channel strip:
m Click the channel strip’s Solo button. Click the button again to unsolo the channel strip.
To exclusively solo a channel strip:
m Option-click the Solo button. Click the Solo button again to unsolo the track, bus, or
output.
When you export a project, all unmuted tracks, busses, and outputs are included in the
exported file. If you export a track, bus, or output that is muted (including being muted
by having another track soloed), the exported file will contain no audio.
