Pitch: Pitch Mod
Here you can make pitch settings for each oscillator. These set-
tings specify how keyboard location will affect the pitch of each
oscillator, and select the controllers that will affect the oscillator
pitch and specify the depth of control. You can also specify the
amount of pitch change produced by the Pitch EG and by LFO1
and LFO2, switch portamento on/off and specify how it will
apply.
Pitch
Pitch Slope
Normally you will leave this parameter at +1.0. Positive (+) val-
ues will cause the pitch to rise as you play higher notes, and neg-
ative (–) values will cause the pitch to fall as you play higher
notes.
With a value of 0, there will be no change in pitch, and the C4
pitch will sound regardless of the keyboard location you play.
The diagram shows how the Pitch Slope and pitch are related:
-1.0…+2.0 Pitch slope value.
Pitch Bend Mode
The Pitch Bend can work in different ways, depending on the
selected option.
Normal Linear bending.
Fixed Scale When this parameter is turned on on an oscilla-
tor, Pitch Bend and Sub Scale have no effect on its
tuning. The relevant parameters are greyed out
and non-selectable. This is useful when assign-
ing to the oscillator a noise (like the breath noise
of a reed) with a fixed frequency, that must not
change on different notes and different pitches.
Highest Pitch Bend only
On this oscillator, Pitch Bend is only activated on
the highest note currently playing on the key-
board.
Lowest Pitch Bend only
On this oscillator, Pitch Bend is only activated on
the lowest note currently playing on the key-
board.
Ribbon to Pitch
Pitch Bend range assigned to the Ribbon Controller.
-12…0…+12 Maximum bending, when touching the extreme
left or right of the Ribbon Controller.
JS (+X)
This parameter specifies how the pitch will change when the joy-
stick is moved all the way to the right. A setting of 12 produces 1
octave of change.
For example if you set this to +12 and move the joystick all the
way to the right, the pitch will rise one octave above the original
pitch.
-60…+12 Maximum pitch change in semitones.
JS (–X)
This parameter specifies how the pitch will change when the joy-
stick is moved all the way to the left. A setting of 12 produces 1
octave of change.
For example, if you set this to -60 and move the joystick all the
way to the left, the pitch will fall five octaves below the original
pitch. This can be used to simulate the downward swoops that a
guitarist produces using the tremolo arm.
-60…+12 Maximum pitch change in semitones.
AMS (Alternate Modulation Source)
This parameter selects the source that will modulate the pitch of
the selected oscillator. See “AMS (Alternate Modulation Source)
list” on page 77.
Intensity
This parameter specifies the depth and direction of the effect
produced by “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 set “AMS” to After Touch and apply pressure
to the keyboard, 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.
-12.00…+12.00
Parameter value.
Pitch EG
The Pitch EG (Envelope Generator) is unique to all oscillators.
Velocity Intensity
This parameter specifies the depth and direction of the modula-
tion that the pitch EG specified on “Pitch: Pitch EG” will apply to
the pitch. With a setting of 12.00, the pitch will change a maxi-
mum of ±1 octave.
-12.00…+12.00
Parameter value.
