This is a base mapping that you can use to add your new features. I already added the Pattern Kit Selector buttons and two modifiers.
Note that Modifier 1 and Modifier 2 are already tracking each side Deck Selector buttons and Shift buttons. The override default mapping is not activated to keep all native mapping functionality.
Select Deck A sets M1 to value 0.
Shift Deck A sets M1 to value 1.
Select Deck C sets M1 to value 4.
Shift Deck C sets M1 to value 5.
Select Deck B sets M2 to value 0.
Shift Deck B sets M2 to value 1.
Select Deck D sets M2 to value 4.
Shift Deck D sets M2 to value 5.
Hold down Shift and press FX Button 2 or FX Button 3 to select previous or next kit in FX Unit 1 or FX Unit 2. This combination will Insert Pattern + Stop + Save Snapshot.
Hold down Shift and press FX button 1 to select next FX Unit mode (Group-Single-Pattern)
