Effets

The Left FX section (FX1) controls by default the effects of the Left selected software deck (1 or 3) and the Right FX section (FX2) controls by default the effects of the Right selected software deck (2 or 4) respectively.
Use the FX ASSIGN (41) buttons to clone (copy) the effects from one to another.

Each one of the FX unit offers 2 modes:
The Single Effect mode offers one effect slot but more parameters controls per effect.
The Multi Effects mode offers 3 effect slots (to trigger more than 1 effect at the same time – chained effects).
The selection between those 2 modes is done by pressing the TAP while SHIFT is held.
