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 Parameter Guide:

• "Using SW 1/2 to turn an AMS source on and off"
on page 100
• "Muting individual Wave Sequence steps with
SW1" on page 100

Controlling Pitch

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 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

• "Generating a static value" on page 104
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 31,
and "1–8: Set Up Controllers," on page 53 of the
Parameter Guide.
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.
The Time parameter controls how long it take the pitch
to change. As this value is increased, the pitch will
change over a longer time. With a value of 000, there
will be no portamento.
You can turn Portamento on and off via SW1 or SW2,
by assigning them to Porta.SW CC#65.
