Program Mode
The Split and Layer Soft Buttons
Simply hit the Split button, and the Forte automatically creates a Multi with two active
Zones. The Program you were using in Program Mode is used in the right hand of the Split
as the Program for Zone 1. After this you can choose a "Split Program" that will be used in
the left hand of the Split as the Program for Zone 2. The Default split program is 245 Finger
Bass.
Once you have saved your Split as a Multi, you can continue to add Split or Layer Zones to
the Multi until you reach the number of Zones allowed. The Forte will display a message if
you have already reached the maximum active Zones.
