Apple Logic Pro 9 - Manual (Page 311)

2 Choose Options > Create New Auxiliary Channel Strips in the Mixer’s local menu bar.
3 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.
4 Choose the 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 ReWire channel to be routed to a particular aux channel strip
in the Logic Pro Mixer. This provides extended mixing and processing options.
To set the ReWire behavior
1 Open Audio preferences by doing one of the following:
• Choose Logic Pro > Preferences > Audio (or use the Open Audio Preferences key
command).
• Click the Preferences button in the Arrange toolbar, and choose Audio from the pop-up
menu.
2 In the Devices pane, choose one of the following from the ReWire Behavior pop-up menu:
• Playback Mode (Less CPU Load): Use this mode when streaming channels via ReWire.
This setting requires less processing power, and should be used when playing back
tracks in ReWire applications.
• Live Mode (Higher CPU Load): Use this mode when you want to play a ReWire instrument
(an instrument running in an external ReWire application) in real time. This setting
requires more system resources, but reduces latency, ensuring that the ReWire
instrument is playable.
Working with External Audio Effects
External audio effects units can be used similarly to the internal Logic Pro effects. You do
this 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 Pro
1 Connect an output (or output pair) of your audio interface with the input (pair) on your
effects unit.
