Alternate Modulation Sources (AMS)

Alternate Modulation Overview

Alternate Modulation lets you use controllers, envelopes,
LFOs, etc. to modulate Program parameters. They're called
"Alternate Modulation" because they are in addition to the
many dedicated modulation routings, such as Filter EG to
Filter Cutoff, or LFO to Pitch.
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 synth
engine (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 a total of 88 destinations for
alternate modulation.
The EXi Common section provides 7 alternate modulation
destinations, the AL-1 provides 92, the CX-3 provides 20,
and the STR-1 provides 131 (not counting the AMS mixers).
For information on other EXi, please see their individual
documentation.
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.

page 89, and "Using the AMS Mixers" on page 42 of the
