Pitch Envelope Generator (Pitch EG) Parameters
These parameters (eleven altogether) determine how the pitch of the voice
changes over time. The Pitch EG parameters affect all operators equally.
The four Level parameters determine the pitch of the operator at five different
points, and the four Rate parameters determine the amount of time that elapses
between changes of pitch. Range, Rate Scaling, and Velocity Switch parameters
give you further detailed control over the Pitch EG effect.
Pitch EG can be used to reproduce the subtle pitch changes of acoustic instru-
ments (for example, at the beginning and/or end of a note). At extreme settings, it
also can be used to create unusual special effects.
• A real-time pitch controller, such as the Pitch Bend wheel on a connected MIDI keyboard, can
be used to augment (or cancel) the "automatic" pitch changes made in the Pitch EG parame-
ters.
• Pitch EG Rate 1 - 4
Range: 0 ... 99
These determine the amount of time that elapses between changes in the pitch (as set in
Level 1 - 4 below).
• Pitch EG Level 1 - 4
Range: 0 ... 99
These determine the overall pitch of the voice at five points in time. A value of "50" corre-
sponds to normal pitch, or no pitch change. Values under "50" lower the pitch, and val-
ues above "50" raise it. The actual pitch range here depends on the
parameter setting. (Higher Pitch EG Range settings result in greater pitch variation.)
The amount of time that elapses between these pitch change points is set in Rate 1 - 4
above.
