4–4: Pitch Common
This page lets you modulate the pitch of Oscillators 1, 2, and
the Sub Oscillator simultaneously, so that the modulation
applies equally to all three oscillators. For example, you can:
• Set up pitch bend from Joystick X (with separate settings
for bending up and bending down).
• Use Pitch Slope to control how the pitch changes when
you play up and down the keyboard.
• Set up Portamento.
• Assign an LFO to modulate the pitch of all three
oscillators simultaneously.
4–4a: Pitch
Pitch Slope [-1.00…+0.00…+2.00]
Normally, this should be set to the default of +1.00.
Pitch Slope, pitch, and note
Positive (+) values cause the pitch to rise as you play higher
on the keyboard, and negative (–) values cause the pitch to
fall as you play higher on the keyboard.
When this is set to 0, playing different notes on the keyboard
won’t change the pitch at all; it will be as if you’re always
playing C4. This can be useful for special effects sounds, for
instance.
If you want to create more complex effects, you can assign
key tracking as an AMS source.
JS+ X [–60…+60]
Sets how much the pitch will change (in semitones) when
you move the joystick to the right. Normally, this is set to a
positive value. For instance, when the value is set to “+12”
and you move the joystick all the way to the right, the pitch
of any notes you play on the keyboard will be shifted up one
octave.
JS– X [–60…+60]
Sets how much the pitch will change (in semitones) when
you move the joystick to the left. Normally, this is set to a
negative value. For instance, when the value is set to “–60”
and you move the joystick all the way to the left, the pitch of
the notes you play on the keyboard will be shifted down five
octaves. You can use this to create guitar-like whammy bar
effects.
4–4b: Portamento
Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.
Enable [Off, On]
On (checked): Turns on Portamento, so that pitch glides
smoothly between notes.
Off (unchecked): Turns off Portamento. This is the default
state.
Fingered [Off, On]
This parameter allows you to control Portamento through
your playing style. When it’s enabled, playing legato will
turn on Portamento, and playing detached will turn it off
again.
This option is only available when Portamento Enable is
turned on.
