WIND™
Part
of
the personality
of
an individual pipe organ relates to the steadiness
of
the wind
supply to the pipes. Because air
is
an elastic medium, there is some amount
of
"give" in the
wind supply
of
every pipe instrument. Some organs exhibit more unsteadiness than others
according to the type
of
wind regulators used (single
or
multiple reservoirs, schwimmer
regulators, etc.). A small amount
of
unsteadiness
in
the wind helps the listener
to
identify
the
sound
as
that
of
a wind-blown instrument, although
too
much can be distracting. Certain types
of
music, though, seem to gain charm from a less-than-perfect wind system.
Another characteristic
of
pipe organs involves changes in pitch which occur
in
individual
pipes when playing large numbers
of
pipes together. These pitch changes are due both
to
variations
in
wind pressure as the wind demand becomes greater and to the influence
of
the
sound from neighboring pipes. This latter effect
is
greatest upon large-scale flute voices and
least upon narrow-scaled string voices. Even though this results
in
significant detuning, the
human ear seems
to
perceive instead an increase
in
ensemble effect.
Rodgers' exclusive Digital Dynamic Wind (patent pending) emulates these characteristics
by modeling the behavior
of
pipe organ wind regulating devices and the response
of
pipes
to
a
slightly unsteady wind supply. Some independent ranks have their own "software reservoir,"
and each voice
is
programmed to respond to wind variations
in
the same way its equivalent
pipe rank or ranks would respond.
WIND
STABILIZER
In order to adjust the behavior
of
the organ wind system, a "WIND STABILIZER" menu
is
provided
in
the Console Display. This stabilizer operates
in
much
the
same way
as
does the
stabilizer control provided on some pipe instruments. In the
"OFF" position, the wind has a
noticeable unsteadiness
in
the playing
of
rapid passages
or
large chords.
The"
1/2" position
reduces this unsteadiness somewhat, and the "ON" position makes the wind steady under
all
conditions. The position
is
saved when the organ
is
turned off.
