Alternate Modulation Sources (AMS)

Alternate Modulation Overview

Alternate Modulation lets you use controllers,
envelopes, LFOs, etc. to modulate Program
parameters. You can use one controller to modulate
multiple parameters simultaneously. You can also
create complex modulation setups in which (for
example) an envelope modulates the frequency of an
LFO, and that LFO is then used to modulate a filter.
As shown in the diagrams below, the parameters you
can control via alternate modulation will depend on
the program type (HD-1, AL-1, CX-3 etc.). For each of
these destination parameters, you can select an AMS
(Alternate Modulation Source) to modulate it.
HD-1 Programs provide 48 types (88 destinations) for
alternate modulation.
The EXi Common section provides 7 alternate
modulation destinations, the AL-1 provides 92, and the
CX-3 provides 20, and the STR-1 provides 131 (not
counting the AMS mixers).
Alternate Modulation Sources
The alternate modulation sources that are available
also depend on the program type.
Each alternate modulation destination can be
controlled by an available alternate modulation source.
If you select two or more Alternate Modulation
destinations for control by the same AMS, a single
source will apply modulation to each of the specified
destinations.

Frequently used assignments such as using Joystick X
to control pitch are provided as special parameters, so
it is not necessary to use Alternate Modulation to
accomplish this.
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.
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 two or more AMS Mixers
together, by one as an input to another.
For more information, see "6–1: OSC 1 AMS Mixer" on
page 89, and "Using the AMS Mixers" on page 58 of
the Operation Guide.
