Controller
The "Tonguing" parameter simulates the half-tonguing technique used by saxo-
phone players by changing the "slit" of the reed. The slit is the space between the tip of
the reed and the mouthpiece. The "Controller" parameter specifies the controller to
be used for tonguing control. When set to "off" no tonguing is applied.
• Please note that accurate keyboard pitch is produced only when maximum
tonguing is applied or the tonguing controller is turned off.
Depth
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 to the right of the param-
eters — the horizontal axis represents the controller value and the vertical axis represents
tonguing.
Curve
Determines the relationship between the controller value and tonguing. When set to
"0" the relationship is linear. That is, a change in the controller value produces a corre-
sponding change in tonguing. 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 to the right of the parameters — the
horizontal axis represents the controller value and the vertical axis represents tonguing.
