• Tonguing Control Depth
• Settings: -127 … +127 (VL-XG Mode: -64 … +63)

Sets the amount of variation produced by the
controller assigned to tonguing. The higher the
value the greater the variation. Positive values
cause an decrease in tonguing in response to higher
controller values (e.g. increased breath pressure or
higher modulation wheel position), while minus
values cause an increase in tonguing in response to
higher controller values. The “Depth” setting is
reflected in the graph at the bottom of the display
— the horizontal axis represents the controller
value and the vertical axis represents tonguing.

 (VOICE mode only)

• Tonguing Curve
• Settings: -16 … +16

Determines the relationship between the controller
value and tonguing. When set to “+00” the rela-
tionship is linear. That is, a change in the controller
value produces a corresponding change in tongu-
ing. As the curve value increases the lower end of
the controller range has relatively little effect on
the sound while higher controller values produce
more dramatic changes. Negative curve values
have the opposite effect: the sound changes
dramatically at low controller values while higher
values produce relatively little effect. The “Curve”
setting is reflected in the graph at the bottom of the
display — the horizontal axis represents the
controller value and the vertical axis represents
tonguing.

• Scream Control Change Number
• Settings: off … 95, AT, VEL, PB

“Scream” drives the entire system into chaotic
oscillation, creating effects that can only be
achieved with physical modeling technology. The
“Scr CC No.” parameter specifies the controller to
be used for scream control. When set to “off”, no
scream variation can be produced via a controller,
but a continuous scream value is determined by the
“30(19): ScrCtrlDpt” parameter, below (negative
values increase the scream level).
•

The “ScrCtrlDpt” parameter, below, must be set
to an appropriate value (higher than “+01” or
lower than “-01”) for scream control to have
any effect.

• Scream Control Depth
• Settings: -127 … +127 (VL-XG Mode: -64 … +63)

Sets the amount of variation produced by the
controller assigned to scream. The higher the value
the greater the variation. Positive values cause an
increase in scream effect in response to higher
controller values (e.g. increased breath pressure or
higher modulation wheel position), while minus
values cause a decrease in scream effect in re-
sponse to higher controller values. The “Depth”
setting is reflected in the graph at the bottom of the
display — the horizontal axis represents the
controller value and the vertical axis represents
scream.
