Chapter 10 Working With Instruments and Effects 261
To manually set up an aux channel for ReWire use:
1 Click the Mixer button at the bottom of the Arrange window. In the Mixer window,
choose Options > Create New Auxiliary Channel Strips.
2 Create as many aux channel strips as required, with the appropriate Format, Input, and
Output settings. For this example, create a stereo channel strip, routed to Input/
Outputs 1-2.
3 Choose the desired ReWire channel in the Input menu of the aux channel strip.
Individual RW Channel entries are available in the Channel menu. These can be
assigned individually, to allow each ReWired channel to be routed to a particular aux
channel in the Logic Express Mixer. This provides extended mixing and processing
options.
Setting the ReWire Behavior
In Logic Express > Preferences > Audio > Devices, you can choose between the
following modes when using ReWired applications:
 Playback Mode (Less CPU Load): Use this mode when streaming channels via ReWire.
This setting requires less CPU power, and should be used when playing back tracks in
ReWired applications.
 Live Mode (Higher CPU Load): Use this mode when you want to play a ReWire
instrument (an instrument running in an external ReWired application) in real time.
This setting requires more CPU resources, but reduces latency, ensuring that the
ReWired instrument is playable.
Working With External Audio Effects
You can use external audio effects units in a similar way to the internal Logic Express
effects. This is achieved with the I/O plug-in, in conjunction with a multi input/output
audio interface.
To integrate and use an external effects unit in Logic Express:
1 Connect an output (or output pair) of your audio interface with the input (pair) on your
effects unit.
2 Connect the output (or output pair) of your effects unit with an input (pair) on your
audio interface.
Note: These can be either analog or digital connections if your audio interface and
effects unit are equipped with either, or both.
