Apple MainStage 2 - Manual (Page 66)

If an instrument supports multiple outputs, one or more multi output versions are available
in the Instrument Plug-In menu for the instrument.
The Plug-In menu shows specific information about output configurations, for
example: EXS24: Multi Output (5xStereo, 6xMono).
Note: Not all instruments support multiple outputs. If no multi output version is available
in the Plug-In menu, the instrument does not support multiple outputs.
To insert a multi output instrument
1 On the channel strip in which you want to use the multi output instrument, click the
Instrument slot.
2 Choose the instrument from the Plug-In menu, and choose the multi output version from
the submenu.
The instrument name appears in the Instrument slot, and a small Add (+) button appears
below the Solo button on the channel strip. The Output for the instrument is set to Output
1-2.
3 Double-click the Instrument slot to open the instrument (plug-in) window.
You need to set up the output routing for individual sounds or samples in the instrument
(plug-in window). You set up output routing for the EXS24 mkII in the Instrument Editor,
and set up output routing for Ultrabeat in the Output menu of the Assignment section
of the Ultrabeat window.
