to simulate the downward swoops that a guitarist produces using the trem-
olo arm.
Choosing a pitch modulation source
▪ Use the Pitch > AMS (Alternate Modulation Source) pop-up menu to select a
modulation source for the pitch of the selected oscillator. A list of the avail-
able AMS sources is in the Appendix.
The
Intensity parameter (-12.00…+12.00) specifies the depth and direction
of the effect produced by the AMS. With a setting of 0, no modulation will be
applied. With a setting of 12.00, the pitch will change up to one octave.
For example, if you choose the JS (-Y) AMS and move the joystick down-
wards, the pitch will rise if this parameter is set to a positive (+) value, or fall
if this parameter is set to a negative (–) value. The range is a maximum of
one octave.
Controlling the Pitch EG (Envelope Generator)
Use the Pitch EG parameters to controls the Pitch EG unique to all oscilla-
tors.
Linking pitch to the envelope
▪ The Velocity Intensity parameter (-12.00…+12.00) specifies the depth and
direction of the Pitch EG modulation. With a setting of 12.00, the pitch will
change a maximum of
±1 octave.
Linking pitch to an AMS modulation
▪ Use the Pitch EG > AMS parameter to select a modulation source for the
pitch EG of the selected oscillator. A list of the available AMS sources is in
the Appendix.
▪ Use the Pitch EG > Intensity parameter to specify the depth and direction of
the AMS. For example, if you choose the Velocity AMS and set this value to
+12.00, the velocity will control the range of pitch change produced by the
pitch EG in a range of
±1 octave. As you play more softly, the pitch change will
draw closer to the pitch EG levels.
