Diverse modulation settings
(AMS and AMS mixer)
Using AMS
AMS (Alternate Modulation Source) lets you modulate
program parameters using controllers, EG, or LFO as the
modulation source. Extremely creative types of modulation
are possible; for example, you can use a single controller to
simultaneously modulate multiple parameters, or you can
use an EG to modulate an LFO's frequency and then use that
LFO to modulate a filter.
AMS (Alternate Modulation Source) refers to any of the
assignable modulation sources in KROSS, including:
• Controllers of the KROSS itself, such as the modulation
wheel, the pitch bend wheel, and SW 1/2
• Incoming MIDI controllers
• Modulators such as the Filter, Pitch, and Amp EGs, the
LFOs, or the AMS Mixers
Intensity is a parameter that sets the degree (speed, depth,
amount etc.) of how AMS will control the modulation.
A number of frequently-used modulation routings, such as
using the modulation wheel or the pitch bend wheel to vary
the pitch, are provided as additional, dedicated routings,
separate from AMS.
Note that not all AMS sources may be available for some
modulation destinations.

Using the AMS Mixers
The AMS Mixers combine two AMS sources into one, or
process an AMS source to make it into something new.
For example, this lets you use an LFO to modulate a filter's
resonance while also modulating it by an EG. Although
resonance has only one AMS input, using the AMS mixer
makes this possible. You could also do things such as using
the filter EG to control the amount of LFO1. The wide
variety of other possibilities include using the modulation
wheel to control the amount of pitch EG, allowing the pitch
bend wheel to apply bend only to notes played while you
hold down the foot switch.
The AMS Mixer outputs appear in the list of AMS sources,
just like the LFOs and EGs. An AMS mixer's output signal
can be used to modulate a variety of parameters.
This also means that the original, unmodified inputs to the
AMS Mixers are still available as well. For instance, if you
use LFO 1 as an input to an AMS Mixer, you can use the
processed version of the LFO to control one AMS
destination, and the original version to control another.

Finally, you can cascade the two AMS Mixers together, by
using AMS Mixer 1 as an input to AMS Mixer 2.
For details, please see "12: P–AMS MIXER" on page 45 of
the Parameter Guide.
Tips for using AMS
When adjusting 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 modulation wheel to control the feedback, you would
select assignments where the modulation wheel controls the
filter frequency and resonance.

For each program, the function of the SW1 and SW2 buttons
can be assigned in the P-INPUT/CTRL> CONTROLLERS
page.

SW2" on page 39.
