Detune Type (Normal or Equal)
With Normal selected, the percentage of detuning remains the same over the entire
range of the keyboard, so the effects of detuning sound the same no matter which
key you play. With Equal selected, the absolute amount of detuning remains the
same over the entire keyboard, so any detuning seems less pronounced as you play
higher up on the keyboard.
Pitch (Page 2)
Pitch Wheel Range (0 to 12 semitones)
Determines the maximum amount of pitch bend when the pitch bend wheel is either
full forward or back. Example: When set to 12, the pitch wheel will bend ±1 octave
(12 semitones).
Aftertouch Depth (-99 to +99)
At +00, aftertouch has no effect on pitch. Applying aftertouch (by pressing harder on
the keyboard, or via MIDI messages) with this parameter set to a positive value
raises the pitch; conversely, applying aftertouch through a negative value lowers the
pitch. The higher the number (either positive or negative), the greater the amount of
pitch change for a given amount of aftertouch.
Tip: Aftertouch is useful for creating keyboard-controlled string bend effects. Low
settings are good for "humanizing" synthesized sounds, since aftertouch changes can
give very slight pitch changes, as associated with acoustic instruments.
Pitch LFO Depth (-99 to +99)
At +00, the pitch LFO has no effect. Higher positive values increase the amount of
Pitch LFO modulation. Negative values give the same apparent effect, but with
reversed LFO phase (i.e., if the pitch would normally be increasing with depth set to a
positive number, the pitch would instead be decreasing at that same moment had the
depth been set to a negative number). Pitch LFO parameters (such as speed and
wave shape) are programmed within the PLFO Function (see page 65).
Pitch Envelope Depth (-99 to +99)
At +00, the pitch envelope has no effect. Positive values raise the pitch from the
baseline according to the envelope shape, while negative values similarly lower the
pitch. The higher the number (negative or positive), the greater the effect. Pitch
Envelope parameters (such as attack and decay time) are programmed within the
PENV Function (see page 69).

Pitch (Page 3)
About portamento: When you play a key and then a second key, normally the
sound jumps instantly from one pitch to another. Portamento provides a sweeping
glide from one note to another over a variable amount of time. A good example of this
type of sound is a steel guitar, where a note slides from one pitch to another.
