About Modulation
To modulate something is simply to cause it to change. Within the voice
architecture of the EPS-16 PLUS we begin by setting basic, or manual, levels for
the volume, pitch, brightness, etc. of a voice, and we then modulate those levels
in various ways in order to create movement and dynamics.
Suppose you switch on your stereo, and turn the volume half way up. We can
call this the manual volume setting. It will stay at that level until it's changed
Now suppose that you take the volume knob of your stereo and begin quickly
turning it up and down, so the volume gets continuously louder and softer, louder
and softer. What you would be doing is modulating the volume of your stereo.
If you were to take the treble control, and do the same to that knob, you would be
modulating the brightness of your stereo.
In much the same way we modulate various levels within the EPS-16 PLUS
(though generally the approach is less haphazard). There are 15 different
Modulation Sources available, and they can each be independently assigned to
vary the manual levels for a great many aspects of a voice, including real time
control of some aspects of an effects program.
Selecting a Modulator
On those programming pages where a modulator can be selected to vary the level
of some function within an EPS-16 PLUS voice, the display shows
MOD= (short for Modulation Source). A modulator is chosen by
selecting (underlining) that parameter with the Left/Right Arrow buttons, and
then using the Data Entry Slider or the Up/Down Arrow buttons to select
among the 15 available modulation sources.
Hint: Moving the Data Entry Slider all the way up selects OFF, which is handy if
you don't want a modulator applied in a particular location.
Let's take, for example, the Pitch Mod page, which is where you apply
modulation to the pitch of a Wavesample. Press Edit, then Pitch. Next, press
the Right Arrow button repeatedly until the following page appears:
Modulation Amount
As shown above, where a modulation source is selected, the parameter
immediately to its right controls the Modulation Amount (the display shows
• ± ##) which controls how deeply the selected modulator will affect the level to
which it is being applied.
