To control the filter modulation, move the green sliders of the first modulation channel
in the router. This controls the modulation intensity.
Using FM Intensity and Frequency to Create ES2 Sounds
The FM Start setting is great for familiarizing yourself with linear frequency modulation
(FM) synthesis. You’ll hear an unmodulated sine sound, generated by Oscillator 1.
Oscillator 2 is switched on and set to produce a sine oscillation as well, but its level is set
to 0: Drag the small square in the uppermost corner of the Triangle to change the settings.
In the ES2, Oscillator 1 is always the carrier, and Oscillator 2 the modulator. In other words,
Oscillator 2 modulates Oscillator 1.
Adjust the intensity of the frequency modulation by slowly moving the wave selector
from Sine to FM. You will hear a typical FM spectrum, with the carrier and modulator
set to the same frequency.
Alter the modulator frequency (Oscillator 2) by adjusting Fine Tune from 0 c to 50 c.
You’ll hear a very slow frequency modulation, which can be compared to the effect of
an LFO. The frequency modulation, however, takes place in the audio spectrum. It is
adjusted in semitone steps by the frequency selector. Check out the entire range from
−36 s to +36 s for Oscillator 2. You’ll hear a broad spectrum of FM sounds. Some settings
will remind you of classic FM synthesizer sounds.
Select other waveforms for Oscillator 2. Sine is the classic, standard FM waveform, but
other waveforms lead to interesting results as well, especially the Digiwaves.
You will achieve further interesting results by altering the carrier (Oscillator 1) frequency.
Check out the entire range, from −36 s to +36 s here, as well. The odd intervals are
especially fascinating. Note that the basic pitch changes when you do this.
Controlling ES2 FM Intensity with an Envelope and FM Scaling
In the FM Envelope setting, you can control the FM intensity with an envelope, generated
by Envelope 2. The modulation target is the range that falls between Sine and FM in the
Oscillator wave selector. The first Router channel is used for this modulation routing. You
can control a wider range by using additional modulation routings, which have been
pre-prepared for you. All you need to do is set their values. As these modulations work
without velocity sensitivity, you can set them in the Editor view by moving both the lower
and upper fader halves to their topmost positions.
Set the second modulation channel to 1.0. You’ll hear how the modulation now
“wanders” through a broader sound range.
Set modulation channels 3 and 4 to a value of 1.0 as well, and listen to the increase in
the sound range.
