Source Buses

These buttons are used to select sources on the buses that the rows are assigned to. The lower two rows select sources on the Background (upper) and Preset (lower) buses of the ME that the row is assigned to. The upper row(s) select sources on the key or aux buses that the rows are assigned to.

The Double-Down control panel has two upper rows and mnemonic buttons to the right of each row to show what the button row is assigned to. The the standard control panel only has a single row and a two-line display showing how the buses are assigned.
