256 Chapter 21 ES2
The sine wave can be modulated in frequency by Oscillator 2 in the audio frequency
range. This kind of linear frequency modulation is the basis on which FM synthesis
works. FM synthesis was popularized by synthesizers such as Yamaha’s DX7 (the
architecture of which is much more complex, when it comes to FM synthesis).
A click on the oscillator number disables the output of Oscillator 1.
Note: Even when Oscillator 1 is turned off, it is still available for use as a modulation
and synchronization source for Oscillators 2 and 3.
Digiwaves
The ES2 not only features the most popular synthesizer waveforms, but also a selection
of 100 additional waveforms, called Digiwaves.
To select a Digiwave:
m Set the Waveform knob to Sine, then do one of the following:
 Control-click the Sine label, and choose the desired waveform from the pop-up
menu.
 Click-hold the Sine label and move the mouse vertically.
∏ Tip: You can select the Digiwave numerically when you hold Shift.
The number of the Digiwave is a parameter that can be modulated. By modulating the
OscWave target, you can scroll through the list of Digiwaves. Choose a sufficiently low
modulation intensity and speed to hear the single Digiwaves being crossfaded. The
Digiwaves of the three oscillators can be modulated individually or together. The
modulation targets are discussed in “OscWaves” on page 274, through to “OscWaveB”
on page 275.
Given the ES2’s ability to modulate Digiwaves, you can produce sounds reminiscent of
classic wavetable synthesizers from PPG and Waldorf (and Korg’s Wavestation).
