Simulating the Creation of Organ
Tones (Tone Wheel Mode)
When any of the “Tone Wheel 1–10” Tones is selected for any
of the Local Parts (UPPER1, UPPER2, LOWER), you can
perform in “Tone Wheel mode,” in which the creation of
organ sounds is simulated.
An organ features nine “harmonic bars” that can be drawn in
and out, and by using the bars in different combinations of
positions, a variety of different tones can be created.
Different “Feet” are assigned to each bar, with the pitches of
the sounds being determined by these “Feet.”
You can simulate the creation of tones using the harmonic
bars by assigning Feet to the PART LEVEL sliders.
While there are only four PART LEVEL sliders, you can
switch the Feet setting by turning the PART SWITCH
buttons on and off, thus allowing you to assign eight Feet
settings to the sliders.
1. Bring up the Tone screen (p. 32).
If the Tone screen is not currently displayed, press
[EDIT] or [MIDI TX] so that the indicator is turned off.
2. In the Tone screen, select an [ORGAN] “Tone Wheel 1–
10” Tone for one of the Parts.
3. Press the CURSOR [ ] button.
The following Tone Wheel screen appears.
This Tone Wheel screen appears only when a Tone
Wheel Tone is selected for one of the Parts in the Tone
screen.

4. Press a TONE SELECT button to select one of the Tone
Wheels from 1 through 10.
While the Tone Wheel screen is displayed, the TONE
SELECT buttons provide for selection among Tone
Wheels 1–10.
5. When the PART LEVEL sliders are moved, the harmonic
bars move in the display, and the tone changes.
By pressing the PART SWITCH buttons on and off, you
can adjust the sounds for other Feet.
If the cursor is moved to the value at the bottom of the
screen, you can adjust the sounds for Feet with [DEC/
NO] and [INC/YES].
6. Press CURSOR [ ]/[ ] to move the cursor to
<Perc> and press [DEC/NO] or [INC/YES] to change
the value.
Perc (Percussion) adds an attack-type sound to the
beginning of the note to give the sound more crispness.
The attack sound changes according to the value.
NOTE
The Percussion is applied only to the UPPER1 Tone.
The settings changed here are stored to each Tone.
Even when you exit from Tone Wheel mode, you can press
[ORGAN] to select the Tone with the changed settings.
Changing the Undulation of the Organ
Tone (Rotary Effect)
While the Tone Wheel screen is displayed, you can change
the undulation rate of the Rotary effect with the Pitch Bend
lever.
The Rotary effect is an effect that recreates the sound of the
rotating speakers used to augment the sound of an organ.
The Rotary effect is set to alternately rotate more rapidly or
slowly when the Pitch Bend lever is moved to the left and
right; the direction is not fixed.
This Pitch Bend Lever setting is effective only in the Tone
Wheel screen.
What Are “Feet?”
Feet basically refers to the lengths of pipe used in pipe
organs. The length of pipe used to produce the reference
pitch (the fundamental) for the keyboard is eight feet.
Reducing the pipe to half its length produces a pitch one
octave higher; conversely, doubling the pipe length
creates a pitch one octave lower. Therefore, a pipe
producing a pitch one octave below that of the reference
of 8’ (eight feet) would be 16’; for one octave above the
reference, the pipe would be 4’, and to take the pitch up
yet another octave it would be shortened to 2’.
Settings Description
OFF No percussion is added.
2nd
Percussion sounds at a pitch one octave
above that of the key pressed.
3rd
Percussion sounds at a pitch an octave and
a fifth above that of the key pressed.
Slow
The percussion’s attenuation time is length-
ened. This softens the sense of attack.
Fast
The percussive sound will decay more
quickly. This gives more of a sense of attack
for a sharp sound.
