Use pulse width modulation in ES2<br />
You can alter the tonal color of rectangular waveforms by scaling the width of waveform pulses<br />
to any value. This is known as pulse width modulation.<br />
ES2 pulse width modulation features are extensive. For example, if rectangular waves are chosen<br />
for all oscillators, you can simultaneously modulate the pulse width of oscillator 1 and the<br />
synchronized pulse waves of oscillator 2 (or the square wave of oscillator 2’s ring modulator) and<br />
oscillator 3.<br />
Set a basic pulse width in oscillator 2 or 3<br />
mm<br />
Drag the waveform rotary control that surrounds the Wave knob (see the highlighted area in the<br />
image above).<br />
Only oscillators 2 and 3 allow you to define a base (default) pulse width, prior to any pulse<br />
width modulation.<br />
Set up a pulse width modulation (of oscillator 1) in the router<br />
1 Choose a rectangle wave for oscillator 1.<br />
2 In the router, choose Osc1Wave as the target, and LFO1 as the source.<br />
3 Adjust the modulation amount slider (try a value of 0.12).<br />
4 Choose a sine wave for LFO 1.<br />
5 Adjust the LFO 1 Rate (around 0.160 Hz for a slow sweep).<br />
