represents the controller value and the vertical axis
represents breath noise.
The amount of breath noise produced also
depends on pressure, so the breath noise curve
indicated by the graph at the bottom of the
display may not always accurately reflect the
perceived curve.
Sets the amount of variation produced by the
controller assigned to growl. The higher the value
the greater the variation. Positive values cause an
increase in growl effect in response to higher
controller values (e.g. increased breath pressure or
higher modulation wheel position), while minus
values cause a decrease in growl effect 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 growl.
37: Grl Curve
 (VOICE mode only)
• Growl Curve
• Settings: -16 … +16
Determines the relationship between the controller
value and growl. When set to “+00” the relation-
ship is linear. That is, a change in the controller
value produces a corresponding change in growl.
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 growl.

• Growl Control Change Number
• Settings: off… 95, AT, VEL, PB
“Growl” produces a periodic pressure modulation
which produces the “growl” effect often heard in
wind instruments. The “Grl CC No.” parameter
specifies the controller to be used for growl
control.  When set to “off”, no growl variation can
be produced via a controller, but a continuous
growl value is determined by the “36(23):
GrlCtrlDpt” parameter, below (negative values
increase the growl level).
The “GrlCtrlDpt” parameter, below, must be set
to an appropriate value (higher than “+01” or
lower than “-01”) for growl control to have any
effect.
