Modifying the Organ Sound
Using the Harmonic Bars
The harmonic bars are assigned to sounds of dierent footage
(pitch). You can create a wide variety of organ sounds by layering
these sounds.
The volume will be loudest when the harmonic bars are fully
lowered; there will be no sound when the harmonic bars are fully
raised.

Harmonic bars and the pitch of the sound
When the middle C (C4) note is pressed, each harmonic bar
will sound the following notes.

There are three colors of harmonic bars. Those that are in
octave multiples of 8’ are white, those that are not octave
multiples are black, and the lower-pitched bars are brown.
A tonewheel organ’s overtone structure
In certain regions of a tonewheel organ’s keyboard, the
overtones will not correspond to the conguration of the
harmonic bars. In order to prevent unpleasantly high or low
pitches, the high footage is “folded back down” in one octave
units for the high range, while the low footage is “folded
back up” in one-octave units for the low range. The VR-09
faithfully reproduces this characteristic of tonewheel organs.
