Send signals to multiple destinations
You can route a signal to several output destinations, using aux channel strips.
For example, you might have a main signal with the output destination set to external speakers.
At the same time, you want to hear the signal as a separate headphone mix, including some
additional effects. To do this, you would set up two separate output destinations for your signal,
with the aux channel strips controlling the headphone mix, including the additional effects.
Output a single channel strip to two destinations
1 Click-hold the channel strip’s Output slot, then choose the main output destination for the mix,
such as speakers.
2 Click-hold the channel strip’s Send slot, then choose the bus to send the separate signal to.
An aux channel strip is created automatically. Your chosen bus is reflected in the aux channel
strip’s Input slot.
3 Click-hold the aux channel strip’s Output slot, then choose the second output destination for the
mix, such as headphones.
Your signal flow is now routed to two separate output destinations. The main signal flow to the
speakers is heard in its “dry” state. The second signal flow—via a bus to the aux channel strip, and
output to headphones—can be modified and heard in its “wet” state.
Use multi-output instruments
There are two reasons to use multi-output instruments in your mix:
•
To process each sound individually in a drum kit, for example, with different effects
•
To route the different software instrument outputs to different outputs on your audio interface
Logic Pro supports the multiple outputs of Drum Kit Designer, the EXS24 mkII, Ultrabeat, and all
Audio Unit instruments. One or more multi-output options may be displayed in addition to the
mono and stereo versions shown in the plug-in pop-up menu of the Instrument slot.
Note: Not all instruments offer multi-output options.
