Alternate Modulation Sources (AMS) The effects of AMS on various parameters, and example applications
Notes for the table
*1 EXT(+–): Pitch Bend, Knob Mod1: CC#17, Knob Mod2:
CC#19, Knob Mod3: CC#20, Knob Mod4: CC#21
*2 When Tempo is selected as an AMS source, the base value is
=120.00.
For example if the Pitch AMS is set to Tempo, and Intensity is
set to 12.00, doubling the tempo value ( =120.00 → 240.00)
will raise the pitch one octave, and halving the tempo (
=120.00 → 60.00) will lower the pitch one octave. The stated
modulation results are for tempo values between 60bpm and
240bpm. As the tempo decreases from 60 to 0bpm, AMS
modulation will have increasingly negative effects; as it
increases from 240 to 250bpm, modulation will have
increasingly positive effects.

*4 It is possible to control LFO Frequency by using Tempo AMS
and Intensity. However if you use the Frequency MIDI/Tempo
Sync function (see page 41), the LFO frequency can be
synchronized to the tempo and note value.
The effects of AMS on various
parameters, and example applications
We'll describe some examples of using alternate modulation.
Pitch (see page 15)
Pitch can be controlled by the Common LFO, filter/amp EG,
controllers, or tempo etc.
• If you select Filter EG or Amp EG as the AMS and set
Intensity to +12.00, the pitch will change up to ±1 octave in
synchronization with the EG.
• If you select Tempo as the AMS and set Intensity to +12.00,
doubling the tempo (based on =120.00) will raise the pitch one
octave, and halving the tempo will lower the pitch one octave.
Pitch EG (see page 15)
Pitch EG intensity can be controlled by the Common LFO,
keyboard tracking, controllers, or tempo.
• If you select M.Wheel:#01 as the AMS and set Intensity to
+12.00, moving the modulation wheel away from yourself will
gradually increase the effect of the Pitch EG to a maximum of
±1 octave. If Intensity has a negative value, the effect of the
Pitch EG will be inverted.
LFO 1/2 (see page 16)
Pitch modulation intensity of the LFO1/2 can be controlled by the
Common LFO, an EG, keyboard tracking, controllers, or tempo
etc.
• If you select EG as the AMS, the pitch change width of LFO
modulation etc. can be controlled in synchronization with the
level changes of the EG. With positive (+) settings of Intensity,
the vibrato effect will gradually deepen as the EG level rises, or
gradually lessen as the EG level decreases. With negative (–)
settings of Intensity, the LFO phase will be inverted.
• If you select a controller such as SW1 or 2 as the AMS, you can
press the SW1 or SW2 switch when desired to turn on the
vibrato effect.
Filter (Cutoff) Frequency (see page 23)
The cutoff frequency of filter A/B can be controlled by the pitch/
amp EG, Common keyboard tracking, controllers, or tempo. Use
the 3–3: Filter1 Modulation page Filter A/B Modulation (P–
FILTER> MOD) to set AMS and Intensity for Filter A or B.
• If you select M.Wheel*#01 as the AMS1 or AMS2 and set
Intensity to a positive (+) value, moving the modulation wheel
away from yourself will raise the cutoff frequency, and moving
it toward youself will lower the cutoff frequency. Negative (–)
settings will have the opposite effect.
• If you select the same controller as an AMS1 or AMS2 and set
separate intensities for Filter A (Low Pass Filter) Intensity and
Filter B (High Pass Filter) Intensity, you can use a single
controller to simultaneously control the cutoff frequencies of
both filters.
Resonance (see page 23)
You can use the EG, LFO, keyboard tracking, controllers, or tempo
etc. to control the resonance level.
• If you select Filter KTrk or Amp KTrk as the AMS, you can
use the filter or amp keyboard tracking settings to control the
resonance level. For example if the amp keyboard tracking
parameters Ramp BtmLo and Ramp HiTop are set to positive
(+) values, Amp KTrk is selected as the AMS, and Intensity it
set to a positive (+) value, playing toward either end of the
keyboard will cause amp keyboard tracking to increase the
volume, and AMS to raise the resonance level.
• You can select a controller as the AMS, and apply resonance
when desired by using the controller.
• You can select Common LFO, LFO1 or 2 as the AMS, and use
the LFO to control the resonance level.
Output (see page 23)
You can use the EG, LFO, keyboard tracking, controllers, or tempo
etc. to control the output level of Filter A/B.
• Set the Filter Routing to Parallel, and specify the desired Type
and other settings for Filter A and Filter B. Set the AMS to
LFO for Filter A and Filter B, and set the LFO to +99 and –99
respectively. The output of Filter A and Filter B will be
cyclically faded-in/out by the LFO.
Filter EG Intensity (see page 24)
Filter EG intensity can be controlled by the Common LFO,
Common keyboard tracking, a controller or tempo etc. You can
use Intensity to A and Intensity to B to independently specify the
intensity for Filter A and B.
• If you choose JS-Y:#02 for AMS, set Intensity to A and
Intensity to B as positive (+) values, and move the joystick of a
synthesizer connected to the KROSS in the -Y direction, the
Filter EG effect will gradually increase. If you set Intensity to
A and Intensity to B to negative (-) values, the filter EG effect
will be inverted.
• If you select Pitch Bend as the AMS and set Intensity to A and
Intensity to B to a positive (+) value, rotating the modulation
wheel away from yourself will gradually increase the effect of
the Filter EG. Rotating the modulation wheel toward yourself
will gradually increase the effect of the Filter EG with an
inverted phase.
Filter LFO1/2 Intensity (see page 25)
The LFO 1/2 filter modulation intensity can be controlled by the
EG, Common LFO, keyboard tracking, controller, or tempo etc.
You can use Intensity to A and Intensity to B to independently
specify the intensity for Filter A and B.
• If you select EG as the AMS, the auto-wah effect produced by
LFO modulation will be controlled by the changes in EG level.
If you set Intensity to A and Intensity to B to a positive (+)
value, the wah effect will deepen as the EG level rises, and will
lessen as the EG level falls. With negative (–) values of
Intensity to A and Intensity to B, the phase of the LFO will be
inverted.
• If you use a controller such as SW1 or 2 as the AMS, you can
apply the auto-wah effect when desired by pressing the SW1 or
SW2 switch.
Filter Common LFO (see page 25)
You can use the EG, LFO, keyboard tracking, controllers, or tempo
etc. to control the Common LFO filter modulation intensity. You
