More AMS Mixer features
There are more mixer Types, including Offset, Shape, and
Quantize, which offer even more possibilities for creative
programming. For more details, see these sections in the

Controlling Pitch

Parameters for controlling pitch are located on the
P2:OSC/Pitch page, as shown below.
P2: OSC/Pitch page
Pitch bend
The JS (+X) and JS(–X) settings specify the amount of pitch
change (in semitones) that will occur when MIDI pitch bend
messages are received or when the joystick is moved to left
or right. A setting of +12 allows the pitch to be controlled a
maximum of one octave upward; a setting of –12 allows the
pitch to be controlled a maximum of one octave downward.
Ribbon specifies the amount of pitch change (in semitones)
that will occur when MIDI control change (CC) #16
messages are received, or when you move your finger left
and right on the ribbon controller. With a setting of +12, the

Suggestions on using AMS
When making settings for alternate modulation, think of the
effect that you wish to produce, what type of modulation will
be necessary to produce that effect, and what parameter of
the oscillator, filter, or amplifier needs to be controlled.
Next, select a source (AMS) and set the Intensity. If you
proceed logically in this way, you will achieve the desired
effect.
For example, if you want to control a guitar sound so that it
approaches feedback when you move the joystick, you might
set up the joystick to modulate the filter frequency and
resonance.
Controller Setup page
For each program, this tab lets you make settings for the
SW1 and SW2 key, and for Real-Time Knobs 5-8. For more
information, see "SW1 and SW2" on page 35, and "1–8: Set
Up Controllers," on page 53 of the Parameter Guide.
pitch will be raised one octave at the far right of the ribbon
controller, and will be lowered by one octave at the far left of
the ribbon controller.
Creating Vibrato
You can use an LFO to create vibrato.
LFO 1/2 Intensity sets the depth to which the selected LFO
will affect the pitch. With a setting of +12.00, vibrato will
produce a maximum of ±1 octave of pitch change.
JS+Y Int specifies the amount of vibrato that the LFO will
produce when the joystick is pushed away from yourself.
Intensity (AMS Intensity) specifies the depth of vibrato that
will be applied by the LFO when modulated by the selected
AMS (Alternate Modulation Source). For example, if LFO1
AMS is set to After Touch and you set an appropriate value
for Intensity, vibrato will be applied when you apply
pressure to the keyboard or when MIDI aftertouch messages
are received.
Pitch EG
When the Intensity value is set to +12.00, the pitch EG
specified in the Pitch EG page will produce a maximum of
±1 octave of pitch change.
To realistically simulate the slight change in pitch that
occurs when a string is plucked or at the attack of a brass or
vocal sound, you can use the EG to create a subtle change in
pitch at the attack.
Portamento
Portamento makes the pitch change smoothly when you play
the next note before releasing the previous note.
