On an instrument with separate divisions (each division having its loudspeakers)
one or more divisions may be connected to a second speaker set. The division
concerned can be switched from the main speaker set to e.g. a speakerset behind
the choir, by means of the switch Choir Antiphonal or Solo/Eth. Antiphonal.
CAN: Cancel
Cancel is a function to switch off all stops at once.
Cantus Firmus (melody coupler)
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 melody coupler
is dropped until a new highest key is played.
Use the stop switches to activate the melody coupler on swell or melody coupler
on choir by
CH: Chorus
Chorus is a function for lightly detuning the organ stops to give it a broader and
livelier sound.
Fix Accessories
When the couplers and the tremulants are used in the fixed (preset) combinations
or free (capture) combinations or when the 0-piston or CAN piston is used, the
couplers and tremulants will change with it. This can be prevented by pressing the
Fix Accessories stop switch. As long as this tab is switched on, the couplers and
tremulants can only be switched on or off manually
KT: Keyboard Transfer
Keyboard Transfer is a function to switch the manuals of the Choir and the Great.
When Keyboard Transfer is active manual 1 is the Great manual and manual 2 is
the Choir manual. Keyboard Transfer also switches the divisional pistons of the
relevant manuals.
MB: Manual Bass (bass coupler)
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 Cantus Firmus in combination with the coupler
SWELL - GREAT because this overrules the solo function of the Cantus Firmus.
