Chapter 3 ES2 41
Use ES2 Digiwaves
In addition to the basic synthesizer waveforms, all ES2 oscillators provide 100 additional
waveforms, called Digiwaves. These are very short samples of the attack transients of various
sounds and instruments.
Choose a Digiwave
m Set the Wave knob to Sine (6 o’clock position), then do one of the following:
•
Control-click or right-click the Sine label, then choose a waveform from the pop-up menu.
•
Drag the Sine label vertically.
•
To select the Digiwave numerically, Shift-click the Sine label, then type a value.
Use the ES2 noise generator
The sonic palette of oscillator 3 is bolstered by the inclusion of a noise generator, which can be
activated by choosing the noise waveform. By default, oscillator 3’s noise generator generates
white noise.
White noise is dened as a signal that consists of all frequencies (an innite number) sounding
simultaneously, at the same intensity, in a given frequency band. The width of the frequency
band is measured in Hertz. Sonically, white noise falls between the sound of the consonant “F”
and breaking waves (surf). White noise is useful for synthesizing wind and seashore noises, or
electronic snare drum sounds.
You can also modulate the tonal color of the noise signal in real time—without using the main
lters of the ES2—by modulating the waveform of oscillator 3.
Change the noise color
1 Set up a modulation routing as follows: modulation target Osc3Wave, source ModWhl. The
modulation amount slider behaves somewhat dierently with this routing, essentially acting like
a lter.
2 Use negative modulation amount values (not −1.000) to set a descending lter slope that
roughly equates to 6 dB/octave. The sound becomes darker (red noise) as you adjust the mod
wheel downwards.
3 To tune this pseudo lter down to 18 Hz, set the modulation amount to −1.000. When Osc3Wave
is modulated positively, the noise becomes brighter (blue noise).
4 If you choose a modulation amount value of +1.000 for the Osc3Wave modulation target, the
lter cuto frequency is set to 18 kHz.
