Swell division on the Great manual. (“
Swell to Great
” literally means, “connect the
Swell
division
to
the
Great
manual”). Couplers allow you to control a larger portion of the organ from
one manual or the pedalboard and are useful in achieving larger or more varied registrations.

Intermanual Couplers
An
Intermanual Coupler
is a control that allows a division of the organ to be played from a
different manual or the pedalboard. They most often function from tabs located above the
Swell manual (also called the tab rail).
The pitch designation (16, 8, 4) specifies the pitch at which the division is to be coupled. 8’
is
concert pitch
in organ nomenclature; when using an 8’ coupler, the division is coupled at
its normal pitch.
4’ pitch is an octave above 8’ pitch. When a 4’ coupler is used, the division is coupled an
octave higher than normal. This nomenclature is similar to the pitch designation used in
organ stops.
8’ intermanual couplers are commonly used when building large ensemble registrations,
whereas 4’ couplers are usually not employed.
4’ couplers are often used with celeste stops in more gentle registrations; they effectively
increase the number of notes that are sounding and increase the warmth and breadth of
the ensemble.

Intramanual Couplers
Intra
manual
couplers
are different from
inter
manual couplers in that they operate within a
single organ division. These couplers allow you to play stops of the organ at a different pitch
level on the
same
manual where the stop is located. These couplers are often referred to as
Sub Couplers
and
Super Couplers
. For example, by activating the
Swell to Swell 16’
coupler
(
Sub
), the stops selected in the Swell division will sound one octave lower than the key played
on the Swell manual. An exception is the first octave where the lowest 12 notes will only sound
at unison pitch. With the
Swell to Swell 4’
coupler (
Super
) activated, the stops selected in the
Swell division will sound one octave higher than the key played on the Swell manual. An
exception is the last octave where the highest 12 notes will not play if the selected stop is 2' or
shorter.
