Modulation Techniques
There are endless ways to use modulation to enhance a sound. The
modulation matrix has 16 freely assignable modulation paths (mod slots
1-16) with 28 modulation sources, 88 destinations, and 11 dedicated mod
sources including the Mod Wheel, Pressure (aftertouch), Breath Control-
ler, Velocity, and more.
Here are a few useful techniques that you can apply to many sounds. The
first uses the LFOs.
Creating a Stereo Tremolo Effect with an LFO
You can create a stereo tremolo effect by modulating
pan
with the LFO.
First, set up a simple electric piano sound.
To create a simple electric piano sound:
1. Recall the Basic Program and set Oscillator 1 shape to
pulse
.
2. Set filter
cutoff
to 0 and filter
env amount
to 71.
3. Set filter envelope
attack
to 0,
decay
to 90,
sustain
to 22, and
release
to 40.
To create a stereo tremolo effect:
1. In the
lfo
section, select
lfo
2 and set its shape to the triangle wave.
2. With the LFO 2 parameters shown in the main display, press Soft
Button 3 to select the
lfo dest
menu tab, then select
pan
with Soft
Knob 1.
3. Set LFO 2
frequency
to 80 to set the speed of the tremolo.
4. Set the LFO
amount
to 90 to control the intensity of the tremolo (its
width in the stereo field as it pans from left to right).
5. Play some chords. Simple electric piano with stereo tremolo!
