Apple Logic Pro 9 - Manual (Page 777)

Logic Pro supports the multiple outputs of 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 instrument plug-in menu.
The plug-in menu offers additional information about an output configuration, such as:
• Instrument Name: Multi Output (2 x stereo, 4 x mono)
• Instrument Name: Multi Output (4 x stereo)
Note: Not all instruments (Logic Pro or software from another company) are multi-output
capable. If the instrument does not provide a multi-output option, it is not equipped with
multiple output facilities.
To insert and set up a multi-output instrument
1 Choose the multi-output instance in the plug-in menu.
The first two outputs of a multi-output instrument are always played back as a stereo
pair by the instrument channel strip that the plug-in is inserted into.
Additional outputs (3 and 4, 5 and 6, and so on) are accessed via aux channel strips.
