Smoothing
The Smoothing Mixer Type smooths out the AMS
input, creating more gentle transitions between values.
You have separate control of the amount of smoothing
during the attack (when the signal is increasing) and
decay (when it's decreasing).
Low settings provide subtle controller smoothing,
creating more gradual aftertouch, for instance. Higher
settings create auto-fade effects, transforming a quick
gesture into a longer fade-in and/or fade-out event.
Smoothing can also be used to alter the shape of
programmable mod sources, such as LFOs and EGs.
For instance, you can turn a "blip" into a simple
envelope shape, as shown below.

More AMS Mixer features
There are more mixer Types, including Offset, Shape,
and Quantize, which offer even more possibilities for
creative programming.
For details, please see "6–1: OSC1 AMS Mix1" on
page 70 of the Parameter Guide.
Tips for 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 in a guitar sound program where you
want to use the joystick to control the feedback, you
would make assignments so that the joystick controls
the filter frequency and resonance.
Controller Setup page
For each program, the function of Realtime Control
sliders 5–8 and the KYBD-61/73/88 SW1 and SW2
switches can be assigned in the Prog P1: Basic/DT/
Ctrls– Controllers Setup page.
For details, please see "Setting the functions of SW1
and SW2" on page 198.

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
#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.
LFO1 Int. or LFO2 Int. 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.
