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 KROME,
including:
• Controllers of the KROME itself, such as the
joystick, SW 1/2, and the realtime knobs
• 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 joystick 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.
For details on alternate modulation and AMS, please
see below.

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 joystick to control the amount of pitch EG,
allowing the joystick to apply bend only to notes
played while you hold down the foot switch, or
changing the response of a realtime controller.
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 “6–1: OSC1 AMS Mix1” on
page 46 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
knobs 1‐B–4‐B and the SW1 and SW2 buttons can be
assigned in the Prog P1: Basic/Controllers– Controllers
Setup page.
For details, please see “Setting the functions of SW1
and SW2” on page 41, and “Setting the functions of
Realtime Controls USER knobs 1–4” on page 42.
