(defined above). and non-speaking stops (coupler s, trem-
ulants, antiphonal controls, expression couplers,
etc.).
STOP TABLET-The hand engraved plastic tongue that iden-
tifies a stop (voice) and actuates
that voice when turned
on. Most Rodgers stop tablets use LEOs for an instantane-
ous indication of voices on . Totally silent when actuated
by a memory piston, Rodgers LED stop tablets offer
improved reliability over oldel: mechanical action designs.
On Rodgers LED stop tablet consoles, the stop tablets are
arranged
in two rows with the Swell organ the first divi-
sion
on the top row and the Pedal organ first on the lower
row, in line with A.G . O. console specifications.
STRAIGHT
ORGAN-A pipe organ term for an organ that has
a separate individual pipe for each note of each available
voice
on the instrument. Such a design can often be
expanded musically by judicious unification , which
increases the versatility of the instrument. No electronic
organs
can be properly termed "straight organs" since all
involve the
use of a limited number of pitch generators,
tone generators and audio channels to create the effect of
pipe organs
with many more pitch, tone and sound
sources.
STRINGS-These are smaller scaled principal stops that are
decreased in volume and
have brighter timbre. Strings are
useful
as accompanimental stops.
SUSTAIN-A device that permits a more gradual (decay) of
the tone
of a sound. Most commonly affecting only Flute,
Harp, and Carillon stops.
SWELL
ORGAN-The more romantic division of the organ,
named for the fact
that it is enclosed in (] box with shut-
ters
on the front. giving it the ability to "swell" in volume.
The Swell contains Solo and Chorus Reeds, as well as the
Strings
and Celeste stops and full intra manual couplers. It
is normally the top manual on two or three manual
organs.
SYNTHETIC
REED-Using mutation pitches on the organ,
one can often synthesize reed sounds that aren't found on
that particular instrument. For instance, Flutes at 8: 22/ 3:
and 1 :1/ 5 : drawn together and played as a solo melody will
make a fairly respectable Clarinet. A 4' and 22 13 ' Flute (or
an 8' String and a 22/3' Flute) makes a good solo Oboe.
TEST FUNCTIONS-Rodgers instruments include several
microprocessor self-test programs
that may be used as an
aid
in trouble-shooting organ problems. In addition, the
organ test mode also includes special
chiff and level
adjustment programs
used in voicing the instrument.
TOE STUDS-Foot operated chrome switches that duplicate
the memory pistons
and are also used for the Tutti and
reversibles.
TRANSPOSER-A device that raises or lowers the pitch
of the
organ in semi tones (half-steps) allowing the organ
to
sound at a different pitch than it is played. Transposers
should return to normal pitch
when the memory cancel is
used or the organ is shut off. In Rodgers Pipe Augmented
organs, both the pipes and the electronics transpos
e.
TRACKER TOUCH-A mechanism applied to the keyboards of
the modern organ, which simulates the t.op-resistant type
of touch characteristic
of the tracker-action pipe organ.
This touch, available
as an option on the Rodgers, pro-
motes clean , articulate playing.
TREMULANT
-A rhythmic undulation in pitch and/or volume
that
is used as a special effect. Individual divisions usu-
ally have their own tremulants with a Flute Tremulant Full
used to create a Gospel sound from the flute stops.
TUNING
CONTROL-A special control that allows Rodgers
organs to
be quickly tuned to a piano or other instrument
not at
"concert pitch." Pushing the control knob in quickly
retunes the organ to A440.
The tuning control does not
affect the pipes
on Rodgers Pipe Augmented instruments.
TUTTI-A Reversible Action which, when operated, instantly
brings
on Full Organ. When engaged again, the organ
reverts back to its original registration, since this action
does not affect the stop tabs. Rodgers' Tuttis are program-
mable
by one organist.
TWEETER-The high-frequency reproducing unit of a High-
Fidelity speaker; essential for
clarity and brilliance in
organ sound.
UNIFICATION-The switching process whereby a set
of pipes
or tone generators
can be played at another pitch level
(16: 8: 4: 22 /3 : etc.) and/or another division of the organ to
increase the instrument's versatility. Unification in
an
electronic organ is often combined with individual level
controls, filters, etc., eliminating the missing notes
and
lack of tonal variation that are negatives to pipe organ
unification. All electronic organs are unified.
Pitch
gen e r-
ators and tone generators are widely shared in all elec-
tronic organ designs with master clocks and a limited
number of
wave shapes unified to create electronic organs
often claiming equivalency to relatively large pipe
organs.
VA"! ZOEREN, INC.-A pipe organ firm headed by Allan Van
Zoeren, a noted pipe organ finisher and tonal expert. In
1984,
CBS purchased Van Zoeren, Inc. as part of an
expansion of Rodgers pipe organ building capabilities.
VOICING-The complex process following the testing of an
organ, in which every stop in the instrument is carefully
scaled and graded
for correct tone quality. This also
involves making sure that
each stop adds into the ensem-
ble, without asserting itself unduly. A good deal of this is
done at the factory, but it culminates in the finishing proc-
ess at the installation site. Digital tone organ systems are
incapable of
on-Site voicing
by individual notes or voices.
Overall filter per voice organ systems mayor may not
include voicing
by voice, but do not allow for adjustment of
individual notes.
