Glossary
Stop
Each set of organ pipes that produces a different sound is called a
stop.
Tablet
A tablet is a rectangular switch used to select a stop or coupler.
Piston
The round switches arranged below the manual keyboard are called
pistons.
Division
The basic group of sounds corresponding to each keyboard is called
a division.
Registration
A combination of settings for the stops (sounds) and couplers is
called a registration.
General memory pistons (general pistons)
These are the pistons [1]–[5] that are used to store registrations
(combinations of sounds).
Each general piston stores a combination of sounds and coupler
settings for the entire organ.
Division memory pistons (division pistons)
These are pistons [1]–[5] that store the sounds of the MAN I division
(lower keyboard) and MAN II division (upper keyboard).
Memory bank
Memory banks are storage areas that contain twenty different sets
of settings for general pistons 1–5, allowing you to use a larger
number of registrations.
Each bank, from memory bank 1 (M01) through memory bank 20
(M20) contains settings for five general memory pistons, letting you
store a total of 5 x 20 = 100 registrations.
General cancel piston (general cancel)
This is the round piston labeled [0]. It turns off all currently selected
sounds (stops), couplers, and tremulants in a single operation.
Expression pedal
Historically, this refers to a pedal that opens or closes the shutters of
a chamber containing the pipes, thus smoothly varying the volume
and tone.
You can also specify whether this pedal will control just the upper or
lower manual, or the entire organ.
MAN I & PEDAL enclosed piston
You can use the expression pedal to vary the volume or tone. A
setting screen allows you to choose the division whose volume or
tone will be affected, but the C-380 provides a MAN I & PEDAL
enclosed piston which lets you turn on/off control of the MAN I
division and PEDAL division while you play.
Shutter
This setting allows you to adjust the openness of the shutters to
specify the minimum volume that will be in effect when the
expression pedal is completely released.
USER/MIDI coupler
The USER/MIDI couplers allow you to select from a wide variety of
user sounds that are not accessible as tablet stops.
When using an external MIDI sound module, these couplers are also
used to play the external sound module.
Manual couplers
Manual couplers let you play the sound of one manual together (i.e.,
coupled) with the sound of another manual.
[II/I] couples the sounds of manual 2 (the upper keyboard) to
manual I (the lower keyboard), allowing you to play both from the
lower keyboard.
[I/P] couples the sounds of manual 1 (the lower keyboard) to the
pedalboard, allowing you to play both from the pedalboard.
Bass coupler
This causes the lowest note played on manual I (the lower keyboard)
to be sounded using the sound of the pedalboard.
When this is used, the lowest note you finger on the lower keyboard
will be played by the pedalboard sound even though you’re not
actually touching the pedalboard.
