Logic: EXS24 assigning samples to multiple outputs

Open an EXS24 as you would any software instrument in Logic, but make sure you choose "Multi Output"



In the mixer window click the + sign to create additional AUX tracks with EXS24 inputs. (see image below)



Open the patch editor by clicking the edit button on the exs24.



Inside the keymap window of the EXS24 you can specify specific outputs for individual samples. This is available under the routing menu (see image below)
