Chapter 10: Step-by-Step 147
STEP-BY-STEP
• 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.
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.
••• You can think of each
modulation patch as a
“Cord”. You must connect
BOTH ends of a cord for it to
work.
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 cursor under the modulation source. As you slowly
