Vocal
Note that the effects of glide will also vary depending on the Patch's voice
allocation setting, in the Program Edit window. Poly Retrig, Poly Reuse, Mono
Legato, and Unison modes are generally the most suitable for use with Glide, but
you may find that you like other settings as well.
Glottal Pulse
This section controls the basic timbre of the voice, modeling the human voice-box,
or "glottis." The glottal creates a complex waveform, made of a pulse followed by a
period of silence. The rising and falling parameters control the shape of the pulse.
Rising
0.0-100.0. This controls the amount of time that it takes the pulse to rise from zero to
its peak.
Falling
0.0-100.0. This controls the amount of time that it takes the pulse to fall from its
peak back to zero.
Vibrato
Frequency
0.00-7.20 Hz. This controls the initial speed of the LFO.
Frequency Mod
List of Modulation Sources. This sets the modulation source for controlling the
LFO frequency. For a complete list, please see "Modulation Sources" on page 2.
Mod Amount
+/-7.20 Hz. This sets the amount, in Hz, by which the mod source affects the LFO
frequency. When the mod source is at its maximum value, it will add this amount to
the setting on the Frequency knob.
Depth
0-100. This sets the initial depth of the vibrato LFO, before modulation.
Depth Mod
List of Modulation Sources. This sets the modulation source for controlling the
vibrato depth. For a complete list, please see "Modulation Sources" on page 2.
Mod Amount
0-100. This sets the amount by which the mod source affects the vibrato depth.
