..oout Modulation
To modulate something is simply to cause it to change. Within the voice
architecture of the SQ-R 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 w*ithin the SQ-R (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 screens where a modulator can be selected to vary the
level of some function within a SQ-R voice, the display shows "Mod=_
Hint:
(short for Modulation Source). A modulator is selected using the Up/Down
Arrow buttons to choose among the 15 available modulation sources.
Holding the Up Arrow and pressing either the Left or Right Arrow button
selects <OFF>, which is handy if you don't want a Modulator applied in a
particular location.
Let's take, for example, the Pitch Modulation screen, which is where you apply
modulation to the pitch of a voice. Press the Edit Sounds button to place the
SQ-R in Sound Edit Mode. Then press the Bank Select button (this displays
the name of the current bank). While the button is held, press the Up Arrow
button until the PITCH bank is selected. Finally, press the Right Arrow
button until you reach the Pitch Modulation screen (shown below). In addition to
Envelope 1 and the LFO, which are always available, you can choose an
additional modulator to alter the pitch:
Enul=-99 LFO-99
Mod=LF0 * +99
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.
