Phasor lookup in cosine
One common usage of the phasor~ object is to readrepeatedly through a stored table of numbers. In that way, instead of just producing a simple linear ramp shape, phasor~ can actually be used to produce any shape. In this example, we're using it to read repeatedly through one half of a sinusoid, so that we repeatedly get just the positive half of a sine wave.
The cycle~ object actually uses a stored wavetable containing one period of a cosine waveform, and reads through that repeatedly at the specified frequency, as if it had its own internal phasor. But instead of using the cycle~ object's internal phasor, you could use a stopped (0 Hz) cycle~ object just for its wavetable, and use the phasor~ to read through a portion of it, via the right (phase offset) inlet.
