Time to Save?
If you wanted to keep this sound, you would have to SAVE it using the Save
Preset function (the very last screen in the Preset menu). To save a preset,
simply move the cursor to the bottom line of the display, select the preset
location where you want to store it, then press Enter. That's it!
Warning: Saving a preset erases whatever preset was already stored in that
location. The default preset ( -defPreset-, 127, bank 0) is a good place to experi-
ment, since it is only a blank preset.
If you want to re-name your preset, do so using the first screen (Preset Name),
then save the preset again to the same location.
LFO Modulation
Let's investigate how modulation routings can affect the sound. For these
experiments, you use the default preset. If you just wrote over it, there is
another one stored in permanent ROM (127, bank 1). Select any primary
instrument, but leave the secondary instrument turned Off.
The LFOs (Low Frequency Oscillators) generate repeating waves which are
commonly used to animate the sound or create vibrato (a cyclic pitch change).
To create vibrato we can use an LFO to modulate the pitch. As you learned in
the Programming Basics section, Modulation requires a modulation Source and
a Destination. The LFO is the source and Pitch is the destination. The block
diagram below illustrates this connection.

To make the connection between the LFO and the Instrument Pitch, move
through the Preset parameters until you find the screen shown below.

The setting shown indicates that the Pitch Wheel is connected to the Pitch, with
an amount of +127 (full). Press the right cursor button (>) twice to place the

APPLYING THE SAME TYPE OF
MODULATION TO BOTH PRIMARY
AND SECONDARY INSTRUMENTS
WILL TEND TO "FUSE" THEM
INTO A NEW SOUND. APPLYING
DIFFERENT MODULATION WILL
TEND TO SEPARATE THEM.
YOU CAN THINK OF EACH
MODULATION PATCH AS A
"CORD". YOU MUST CONNECT
BOTH ENDS OF A CORD FOR IT
TO WORK.
