Couplers

Manual coupler:
SWELL - GREAT: Fully couples all keys of the Swell to the Great.
Pedal couplers:
GREAT - PEDAL: Fully couples all keys of the Great to the Pedal.
SWELL - PEDAL: Fully couples all keys of the Swell to the Pedal.
Manual Bass (MB):
Couples the Pedal monophonic to the Great. Only the lowest key that is played on
the Great is coupled from the Pedal to the Great.
If only the lowest key of a chord is released, the pedal key activated by the
Manual Bass function is dropped until a new lowest key is played.
Activate the Manual Bass with the MB piston.
It is advisable not to use the Manual Bass while playing the pedal board to avoid
double bass tones.
Cantus Firmus (CF):
Cantus firmus: Latin for 'fixed voice' or in organs 'solo voice' or 'melody coupler'.
Couples the Swell monophonic to the Great. Only the highest key that is played on
the Great is coupled from the Swell to the Great.
With use of a solo registration on the Swell in this way a solo is heard while
playing only on the Great.
If only the highest key of a chord is released, the key activated by the Cantus
Firmus function is dropped until a new highest key is played.
Activate the Cantus Firmus with the CF piston.
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.
