Controller
The "Embouchure" parameter 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 "Con-
troller" parameter specifies the controller to be used for embouchure control. When
set to "off" medium embouchure is applied at all times.
• Please note that accurate keyboard pitch is produced only at medium embou-
chure.
• The actual embouchure value applied to the VL1 tone generator is a mix of
the embouchure from the controller and that from the embouchure and pitch
envelopes (
Upper Depth
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 response to higher controller values, while minus values cause a
decrease in embouchure in response to higher controller values. The value of the "Lower
Depth" parameter, below, is automatically changed in response to changes in the "Up-
per Depth" value (the "Lower Depth" value is always negative when "Upper
Depth" is positive, and vice versa).
Lower Depth
Sets the amount of variation produced by the controller assigned to embouchure
when the controller is set to it minimum position (e.g. a modulation wheel rolled all the
way down). The higher the value the greater the variation. Positive values cause an
increase in embouchure in response to lower controller values, while minus values cause
a decrease in embouchure in response to lower controller values. Changing the value of
the "Lower Depth" parameter has no effect on the "Upper Depth" value. The
