pressure or higher modulation wheel position),
while minus values cause a decrease in amplitude
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 amplitude.

• Amplitude Curve
• Settings: -16 … +16

Determines the relationship between the controller
value and amplitude. When set to “+00” the
relationship is linear. That is, a change in the
controller value produces a corresponding change
in amplitude. 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 amplitude.

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

“Embouchure” corresponds to the tightness of the
lips against the reed or against each other. In a
string instrument voice embouchure corresponds to
how strongly the bow is pressed against the string.
Affects both pitch and timbre. The “Emp CC No.”
parameter specifies the controller to be used for
embouchure control. When set to “off”  medium
embouchure is applied at all times.
•

Please note that with many voices accurate
keyboard/controller pitch is produced only at
medium embouchure.

•

The “EmbUpprDpt” and “EmbLowrDpt”
parameters, below, must be set to appropriate
values (higher than “+01” or lower than “-01”)
for embouchure control to have any effect.

• Embouchure Upper Control Depth
• Settings: -127 … +127

Sets the amount of variation produced by the
controller assigned to embouchure when the
controller is set to its maximum position (e.g. a
modulation wheel rolled all the way up). The
higher the value the greater the variation. Positive
values cause an increase in embouchure in re-
sponse to higher controller values, while minus
values cause a decrease in embouchure in response
to higher controller values.
