Tone's Event classes (<a href="https://tonejs.github.io/docs/Event">Tone.Event</a>,
|
|
<a href="https://tonejs.github.io/docs/Loop">Tone.Loop</a>,
|
|
<a href="https://tonejs.github.io/docs/Part">Tone.Part</a> and
|
|
<a href="https://tonejs.github.io/docs/Sequence">Tone.Sequence</a>)
|
|
simplify scheduling events along the Transport. Each class abstracts away calls to
|
|
<a href="https://tonejs.github.io/docs/Transport.schedule">Transport.schedule</a> or
|
|
<a href="https://tonejs.github.io/docs/Transport.scheduleRepeat">scheduleRepeat</a>
|
|
and lets you create precise, rhythmic events which are startable, stoppable and loopable.
