EDITING EACH TONE WHEEL
WHEEL
Th is allows you to select the Tone Wheel you want to edit.
Th e setting range is displayed by “Wheel Number” and “Note”,
01: 0C to 12: 0B,
F01: 0C to F12: 0B,
13: 1C to 91: 7F# and
F92: 7G to F96: 7B.
“F” denotes wheels used for extended “Fold Back.” Th e non-marked Wheel Numbers
indicate original wheels from the B-3/C-3.
Th
ere are two ways to select the Wheel Number:
1. Use the [VALUE] knob, or,
2. If you want to locate a certain Tone Wheel quickly, move the Drawbar slightly
while depressing the key you want to regulate (see the illustration on the right).
When the Wheel Number is selected, each Parameter for the wheel ( to ) is
updated.
NOTE: Make sure [TRANSPOSE] and [OCTAVE] are set at “0” to ensure that the correct Wheel
is selected.
LEVEL (TW)
Setting Range: -Inf, -92.0 ~ +4.0 [dB]
Th is allows you to adjust the volume of the selected Wheel.
HPF (TW)
Setting Range: 0 ~ 127
Th is allows you to adjust the “HPF” ( High-Pass Filter) , which will remove the higher
frequencies of the selected Wheel.
A lower value will introduce a “motor hum” or noise) which will be heard in addition
to the Tone Wheel sound.
LEAK (TW)
Setting Range: 0 ~ 127
Th is allows you to adjust the amount of Leakage sound added to the Fundamental
sound.
A higher value will result in more Leakage.
NOTE: See page 122 for more information about Leakage.

“F” WHEELS AND PEDAL WHEELS
On the B-3/C-3/A-100, there are 91 sounding tone
wheels. Wheels #1 through #12 are special wheels
called
Complex Wheels used exclusively for the
Pedal tones. Later Hammond models had 96
sounding tone wheels, with the Sub-Fundamental
Drawbar (the one marked, “16’”) continuing to play
all the way down to the lowest “C” (“1C”) and 5
additional pitches at the top. On the SK PRO, the
extended pitches are designated as “F” (Fold Back)
pitches (see the illustration below).
DECIBEL (dB)
A decibel (dB) is a unit for measuring the intensity
of a sound. For example, “0dB” is a reference level,
“+6dB” doubles the sound intensity and “-6db”
decreases the sound intensity by about 50%.
NOTE: The Parameters labeled (TW) are Tone
Wheel Parameters. You must Record
these Parameters to a Custom Tone
Wheel if you want their settings to
be remembered the next time the
instrument is turned “ON.” See page
128 for instructions on how to do this.
