280 Chapter 8 Basic Mixing in Soundtrack Pro
Note: You can create submixes independently of the audio hardware connected to your
computer and can route audio to an output that does not correspond to a physical
output. In most situations, each submix in a project should correspond to a physical
output on the audio interface or other hardware connected to your computer. Submixes
that do not correspond to a physical output will not be heard. You may set as many
submixes in a project to the same physical output device or output channel as you like.
To select an audio interface as the output device:
m Choose Apple menu > System Preferences, click Sound, then click the Output button.
Select the audio interface in the list that appears.
For more information about these settings, see “ Setting the Audio Input and Output ”
on page 22.
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 submixes.
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 submixes 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 contains no audio.
Enabling Track Channel Strips for Recording
You can enable a track channel strip for recording. When you enable a track channel
strip for recording, audio will be recorded on the track when you click the Record
button in the transport controls. You can’t record to a bus or output channel strip.
To enable a track channel strip for recording:
m Click the Arm for Recording button in the channel strip. Click the button again to
disable the channel strip for recording.
