DIGITAL DYNAMIC 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.
Adjusting the Wind Stabilizer
1. Press and hold the SET piston.
