Looping

Sometimes it’s useful to have a module loop or repeat its functions. For example, an envelope generator that can be set to loop becomes a low frequency oscillator: as it attacks to a maximum value and decays back to zero, it starts that attack phase again. Quite often you want a note sequencer to loop: When it reaches the last note in the sequence, it would be useful for it to then look back to or return to the first note and start over. Audio recorders with looping features are also popular for live performance.
