Choose the audio output for the channel strip from the Output pop-up menu.

For audio channel strips, choose mono or stereo format from the Format pop-up menu.
Important:
Audio channel strips can produce feedback, particularly if you are using a
microphone for audio input. When you add an audio channel strip, the volume of the
channel strip is set to silence, and Feedback Protection is turned on to alert you when
feedback occurs on the channel strip. When you add an external instrument channel
strip, the volume of the channel strip is set to silence, but Feedback Protection is turned
off.

For software instrument channel strips, you can define the key range for the channel strip
in the Channel Strip Inspector so that the concert-level channel strip does not overlap
software instruments you plan to use in your patches and sets.
For information about defining the key range of a channel strip, see
.
When you add a channel strip at the concert level, you can map screen controls to the
channel strip only at the concert level, not for individual patches or sets.
Using the MainStage Clock
Some plug-ins, including the Playback and Ultrabeat plug-ins included with Logic Studio,
require a time source, and use beat and tempo information in order to play in time.
Additionally, some third-party applications and plug-ins using their own sequencer or
playback engine may behave differently than sequencer-based plug-ins included in
Logic Studio. These plug-ins (which include Reason and other ReWire applications and
Reaktor) require a play message from the host application to begin playback and require
a stop message to end playback. They may also require a continue (also sometimes called
“resume”) message to continue playback from their current time position.
MainStage includes an internal beat clock or “time base” that you can use to control the
playback of these plug-ins. The MainStage clock generates beat, time position, and tempo
information so sequencer-oriented plug-ins can start, stop, and play in time. The MainStage
clock operates similarly to the song position in Logic Pro.
You can send play and stop messages in the following ways:
• Using the Play/Stop button in the toolbar, if it is visible
• Using the Metronome button in the toolbar, if it is visible (turning on the metronome
also starts the MainStage clock, if it is not already running)
• Using a screen control mapped to the Play/Stop, Play, or Stop action
• Using a screen control mapped to the Continue action to resume playback of a
third-party plug-in (but not a Playback plug-in)
