ES2 basic oscillator waveforms<br />
All ES2 oscillators output a number of standard waveforms—sine, pulse, rectangular, sawtooth,<br />
and triangular waves—or, alternately, any of 100 Digiwaves (see Use ES2 Digiwaves on page 42).<br />
The following table covers the basic waveforms:<br />
Waveform Basic tone Comments<br />
Pulse/Rectangular Nasal sounding Great for reed instruments, synth<br />
blips, and basses<br />
Square Hollow and woody sounding Useful for basses, clarinets,<br />
and oboes. The pulse width<br />
of (oscillator 2 and 3) square<br />
waveforms can be smoothly scaled<br />
between 50% and the thinnest of<br />
pulses.<br />
Sawtooth Warm and even Useful for strings, pads, bass, and<br />
brass sounds<br />
Triangle<br />
Sweet sounding, softer than<br />
sawtooth<br />
Useful for flutes and pad sounds<br />
Sine A pure tone The sine wave of oscillator 1<br />
can be frequency modulated<br />
by oscillator 2. This kind of<br />
modulation forms the basis of<br />
FM synthesis (see Use frequency<br />
modulation in ES2 on page 40).<br />
Oscillators 2 and 3 also offer the selection of:<br />
••<br />
A rectangular wave, synchronized to oscillator 1<br />
••<br />
A sawtooth wave, synchronized to oscillator 1<br />
••<br />
A ring modulator, which is fed by the output of oscillator 1 and a square wave from oscillator 2<br />
••<br />
Colored noise for oscillator 3. See Use the ES2 noise generator on page 42.<br />
Oscillator synchronization and ring modulation allow for the creation of very complex and<br />
flexible harmonic spectra. The principles behind oscillator synchronization are described in<br />
Synchronize ES2 oscillators on page 46. Ring modulation principles are described in Use ring<br />
modulation in ES2 on page 41.<br />
