Explanation
When a Structure Type of TYPE 3 or TYPE 4 is selected, you can adjust the depth of the booster . The
booster increases the input signal in order to distort the sound . This creates the distortion effect
frequently used with electric guitars . Higher settings will produce more distortion .
Booster
The Booster is used to distort the
incoming signal .
In addition to using this to create
distortion, you can use the waveform
(WG1) of one of the partials as an
LFO which shifts the other waveform
(WG2) upward or downward to create
modulation similar to PWM (pulse width
modulation) . This parameter works best
when you use it in conjunction with the
Wave Gain parameter (p . 45) .
Fade Upper
Range Upper
This determines what will happen to the tone's level when a note that's higher than the partial's
specified keyboard range is played . Higher settings produce a more gradual change in volume .
If you don't want the tone to sound at all when a note above the keyboard range is played, set this
parameter to "0."
Specifies the highest note that the tone will sound for each partial .
Specifies the lowest note that the tone will sound for each partial .
NOTE
If you attempt to raise the lower key higher than the upper key, or to lower the upper key below
the lower key, the other value will be automatically modified to the same setting .
This determines what will happen to the tone's level when a note that's lower than the partial's
specified keyboard range is played . Higher settings produce a more gradual change in volume .
If you don't want the tone to sound at all when a note below the keyboard range is played, set this
parameter to "0."
PMT Velocity Control determines whether a different partial is played (ON) or not (OFF) depending
on the force with which the key is played (velocity) .
"RANDOM,"
When set to the tone's constituent partials will sound randomly, regardless of any
velocity messages .
When set to "CYCLE," the tone's constituent partials will sound consecutively, regardless of any
velocity messages .
MEMO
Use "Velo Range Lower" (p . 49) and
dynamics .
NOTE
• If Velocity Range Lower and Velocity Range Upper are set to the same values, you won't be able
to obtain any effect by setting PMT Velocity Control to
•
Instead of using Velocity, you can also have partials substituted using the Matrix Control (p . 58) .
However, the keyboard velocity and the Matrix Control cannot be used simultaneously to make
different partials to sound . When using the Matrix Control to switch partials, set the Velocity
Control parameter to "OFF."
