Option	Description
`tick`	Where in the track to start reading, counted from its first tick without going back at the loops. A note that was already sounding there is read from that tick on.

Methods

Method	Description
`until(tick: number): Sound<Settings>[]`	The notes that start before a tick and were not read yet, in the order they start. A track that loops goes back to its loop start each time it reaches its loop end, so the notes before the loop start are read once. `tick`: Counted from the first tick of the song without going back at the loops.
