Linear motion in two voices

Two oscillators, one in the left channel and one in the right channel, play notes that have a continuously changing frequency, at a continuously changing note rate. Every few seconds (some randomly-chosen number of seconds from 2 to 8) each of the two oscillators gets a new destination frequency and destination note rate, and heads toward those destination values over the next few (randomly-chosen number of) seconds.

Sync Multiple sfplay~

The examples above show two different ways that you can trigger sound files while keeping in sync with a particular beat when the durations of the sound files are not perfect multiples of the beat duration, hence triggering the next sound file at the ending point of the current sound file results in the next sound file being started off the beat.

List audio cue points

To set a list of cue points in an audio file and have them played in order, use either sfplay~ (with a set of cues established by preload messages to sfplay~ or to sflist~) or buffer~ (with start messages to play~, the parameters of which are stored in a coll).
