You can assign expression/percussion maps to the endpoints in your project; for example, if you have created a custom percussion map and must link it to the endpoint for the corresponding VST patch.
Prerequisite
You have made or imported any expression/percussion maps that you require but do not exist on your computer.
Procedure
In Play mode, in the VST and MIDI panel, click Endpoint Setup
in the plug-in instance in which you want to change the expression/percussion maps assigned to endpoints to open the Endpoint Setup dialog.
Double-click the expression/percussion map you want to change.
Click the disclosure arrow to the right of the field.
A menu appears containing all maps of the same type currently loaded in your project.
Select the expression/percussion map you want from the menu.
Press Return.
Optional: Repeat steps 2 to 5 for any other endpoints whose assigned expression/percussion maps you want to change.
Click OK to save your changes and close the dialog.
