Larger organs will often have one or two mutation stops from the principal family. In most
cases, these ranks are used to add color to the principal chorus.
Celeste ranks
Celestes are unique among organ stops in that they are intentionally tuned sharp or flat in relation
to the rest of the instrument. Celestes are paired with a partner rank (often called a “unison”)
which is similar in color to the celeste rank but is in tune with the balance of the organ.
When the unison and celeste are drawn together, the tuning discrepancy between the two ranks
creates a beautiful undulating quality suitable for lush, romantic textures. Celestes are either
from the string or flute family, with the latter usually being the quieter of the two.
More about Couplers
Intermanual couplers
Intermanual couplers enable stops of one division to be played on another keyboard or the
pedalboard. Examples of intermanual couplers are SWELL TO GREAT , and GREAT TO
PEDAL . These couplers are located on the tilt tabs above the Swell manual.
The first name listed in the coupler is the division which is being “coupled”; the second name
denotes the division which the division is coupled to. “Swell to Great” literally means,
“Connect the
Swell division to the Great manual.”
The SWELL UNISON OFF coupler is quite unique in that it silences notes at concert or
unison pitch (hence, the name). For example, selecting the SWELL UNISON OFF coupler
would cause activated stops in the Swell division to be silent even when notes are played on
the Swell manual.
The Unison Off couplers are also useful when you want to couple a division somewhere else
without having it sound on its native manual (i.e., you want to couple stops in Swell division
to the Great but don’t want them to play from the Swell manual).
The intramanual Swell Unison off coupler on the T797 is located on a tab located above the
Swell Manual.
Pedal/Great Piston Coupler
The T797 is also equipped with a coupler for the Pedal and Great divisional pistons. When
activated, this causes a Pedal divisional piston to be activated when the same numbered Great
divisional piston is selected. This couples the two sets of Divisional pistons.
To enable or disable the Pedal/Great Piston Coupler:
1. Press and release the QUICKMENU piston.
2. Rotate the Select Knob to highlight
Console
, then press and release
QUICKMENU to select the category.
