EXi: AL-1 Analog Synthesizer

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 both Joystick X (with
separate settings for bending up and bending
down) and the ribbon controller.
• 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.
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.
Pitch Slope, pitch, and note
Ribbon [-60…+60 semitones]
You can use the ribbon controller for pitch-bend. This
parameter specifies, in semitones, the ribbon’s pitch-
bend range.
Positive (+) values make the pitch rise when you press
the ribbon controller to the right of center, and
negative (–) values will cause the pitch to fall.
When you lift off of the ribbon, the pitch will snap back
to the center (unless you’re using the SW1/2 “Ribbon
Lock” feature). So, by tapping on the right edge of the
ribbon and then releasing quickly, you can create
guitar-style “hammer-on” effects.
JS+ X [-60…+60 semitones]
This sets the maximum amount of pitch bend, in
semitones, when you move the joystick to the right.
For normal pitch bend, set this to a positive value.
JS- X [-60…+60 semitones]
This sets the maximum amount of pitch bend, in
semitones, when you move the joystick to the left. For
normal pitch bend, set this to a negative value.
