// desc: basic demo using the Phasor UGen to do modulate the width of a PulseOsc
//
// The phasor linearly ramps from 0 --> 1 every cycle, and rate can be controlled
// programmatically. Note: this is *not* intended to be a sound-generating UGen!
// It is more commonly used to modulate other signals or do lookups in a wavetable.
// For example, in this demo, the phasor signal modulates the PulseOsc width.
// 
// Although the phasor signal is the shape of a Sawtooth, it performs no anti-aliasing!
// For a sawtooth shaped signal, use SawOsc instead.
