Setting the Parameters

LEAKAGE NOISE
On the B-3/C-3, the signal leakes in the route from
the pick-up mounted for the Topnewheels to the
output terminal, thus noise (= mixed Tone-wheel
sound) was also heard, This is called “Leakage
Noise”.
The “Leakage Noise” is an obstacle in making pure
tones, but it is recognized as a character now.
“Mellow”, “Brite” and “Saw” does not include the
Leakage Noise.
DISTORTION
If you raise the Level and Resonance values too
much, it changes the gain in the sound engine and
may sometimes cause distortion, i.e. unpleasant
noise.
In such a case, please lower these values.
4. WHEEL NUMBER
Select the Number of the Wheel you want to regulate.
To select the Wheel Number, select the [VALUE] button or
the [VALUE] knob here, or slightly move the feet of the Draw-
bar 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 (5, 6, 7, 8) is displayed.
5. LEVEL
This is for setting the volume of this wheel.
The setting range is -20 to +2dB. If you increase the value, it
gets louder.
6. CUT OFF FREQUENCY - LPF
This is for setting the FREQUENCY to cut the TREBLE of
this wheel.
If you increase the value, a leakage noise is heard besides
the original tonewheel pitch.
If you decrease the value, the sound gets sweet and mild, as
the treble is cut off.
The setting range is 0 - 127.
NOTE: If you decrease the value too low below the original
Tonewheel pitch, the wheel volume will be reduced.
7. RESONANCE - LPF
This is for setting the boost or reduce the level in and around
frequency by Cut-Off Frequency - LPF(5).
The setting range is -100 to +100. The more the value gets
boost, and less the value treble is cut smoothly.
8. CUT OFF FREQUENCY - HPF
This is for setting the FREQUENCY to cut the BASS of this
wheel.
If you decrease the value, a motor hum (= noise) is heard
besides the original Tonewheel sound.
The setting range is 0 - 127.
NOTE: If you increase the value too high above the original
tonewheel pitch, the sound will get “thin”.
NOTE: The parameters 2 - 7 are the Tonewheel parameters. If
you do the recording operation of the next page, it works
commonly to the same Tonewheel Set of each Combi-
nation Preset.
NOTE: When you operate the parameters 2 - 7, if you do not
the recording operation of the next page, it is lost when
you turn off the power.
