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.

1. Select an organ sound (p. 13).
The organ sound editing screen appears.
2. Slide the harmonic bars to adjust the sound.
The volume of each footage is shown numerically.

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

The harmonic bars are categorized into two colors. The white
bars are octave multiples of 8’, and the black bars are a lower
octave or are not octave multiples.
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. This unit faithfully
reproduces this characteristic of tonewheel organs.
