Use multi-output instruments in Logic Pro for iPad
You can use multi-output instruments in your mix to process each sound individually with different effects (in a drum kit, for example) or to route the different software instrument outputs to different outputs on an audio interface.
Logic Pro supports the multiple outputs of all instruments that provide a multi-output configuration (including Drum Kit Designer, Sampler, Studio Horns, Studio Strings, and Audio Unit Extensions). 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.
Not all instruments offer multi-output options.
Insert and set up a multi-output instrument
In the Mixer in Logic Pro, tap the Instrument slot on an instrument channel strip, tap Replace, then choose a multi-output instance from the 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.
In the Mixer, tap the Add button (+) above the Solo button on the instrument channel strip for the multi-output instrument.
Note: The Add button (+) appears only on multi-output instrument channel strips.
An aux channel strip is created to the right of the multi-output instrument channel strip. Use this new channel strip to isolate and route a sound for independent mixing and processing.
Repeatedly tap the Add button (+) to create more aux channel strips for all stereo or mono outputs available to the instrument plug-in.
You should create only as many aux channel strips as are required for the number of outputs used by the multi-output instrument.
If necessary, you can delete any unneeded channel strips by tapping the channel strip name, then tapping Delete.
