Using Alternate Modulation
(AMS) and the AMS Mixers
Alternate Modulation
AMS (Alternate Modulation Source) refers to any of
the assignable modulation sources in M3, including:
• KYBD-61/73/88 controllers such as the joystick or
ribbon controller
• Built-in physical controllers, such as the Real-Time
Sliders
• Incoming MIDI controllers, or MIDI controllers
generated by KARMA or the X–Y control
• 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.) to which AMS will control the
modulation.
A number of frequently-used modulation routings,
such as using the KYBD-61/73/88’s 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

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 instance, they can add two AMS sources together,
or use one AMS source to scale the amount of another.
You can also use them to change the shapes of LFOs
and EGs in various ways, modify the response of
realtime controllers, and more.
The AMS Mixer outputs appear in the list of AMS
sources, just like the LFOs and EGs.
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 a 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.
Adding two AMS sources together
AMS mixers will do different things depending on
their Mixer Type setting. The A+B setting merges two
AMS sources into one. This can be handy when you
need to add one more modulation source to a
parameter, but you’ve already used up all of the
available AMS slots.
For instance, let’s say that you’re using an LFO to
modulate Resonance, and then you decide that it
would be interesting to scale that parameter with an
EG as well. Resonance has only a single AMS input,
but you can easily merge the LFO and the EG together
using the A+B AMS Mixer:
1. Assign the LFO to AMS A.
2. Assign the EG to AMS B.
3. Assign the AMS Mixer as the Filter Resonance
AMS.
AMS Mixer A+B example
Scaling one AMS source with another
When the Mixer Type is set to Amt A x B, the AMS
mixer uses the AMS B input to scale the amount of
AMS A. For instance, you can control the amount
LFO1 with the Filter EG, or control the amount of the
Pitch EG with the ribbon.
