Melody and Bass Couplers
These controls provide great flexibility. The Melody Coupler allows you to use a different
registration for the top note played on the Great so that you can accentuate the melody note even
though both hands are on one manual. When
SWELL MELODY ON GREAT is activated, the
top note on the Great will use the Swell registration.
The Bass Coupler is similar in concept, except that when it is activated (i.e., the BASS ON
GREAT piston is lit), the bottom note played on the Great will use the registration from the
Pedal division. This allows you to easily add a Pedal part to a piece of music that is played only
on the Great manual.
The Melody Coupler operates over a very specific range from key 25 to key 61 on the Great
manual.
The range of the Bass Coupler at key 1 and extends to key 24 on the Great manual.
About Stop Families
Organ stops are grouped into four main families: Principals, Flutes, Strings and Reeds. Each of
these families is well represented on your Rodgers instrument.
The Principal family is the group of stops unique to the organ; they aren’t imitative of other
instruments. Principals are often referred to as the “backbone” of the organ and play a strong
role in hymn accompaniments and as the foundation of many chorus registrations. Examples of
stops belonging to the Principal family are
Principal , Octave , Super Octave , Choralbass and
Prestant .
In addition, mixture stops, with names such as Mixture and Plein Jeu , consist of multiple
Principal ranks; the Roman numeral following the name denotes the number of ranks contained
in the mixture. For example, a
Mixture IV stop contains four ranks of Principal pipes.
The Flute family consists of stops that are generally imitative of orchestral flutes and recorders.
This is an extremely diverse group of stops that function in a myriad of ways, from acting as a
solo color to serving as the basis of ensemble registrations, either by themselves or in
combination with other stops. Examples of flute stops are the
Bourdon, Gedackt, and Flauto
Traverso.
These settings are retained when the instrument is turned off.
