## Triggering events with each cycle of a phasor~

How do we detect, with sample-accurate precision, the precise moment when **phasor~** begins a new cycle from 0 to 1? We need to detect the sample on which it leaps from 1 back to 0. However, because **phasor~** is constantly interpolating between 0 and 1, it might not leap down to exactly 0. So we can't just use a **==~** object to see when its value is 0.
