PL. These seven memory locations have factory settings (presets) appropriate for
the quiet pianissimo to the loud tutti and the classic plenum.
It is advisable not to use the Cantus Firmus in combination with the coupler
SWELL - GREAT because this overrules the solo function of the Cantus Firmus.
If no expression pedal is configured as a swell pedal for the Swell, the S/S piston
cannot be activated.
