Tracks

Sequence one or more notes.

Examples

Play a single note:

session.track('drums', ({ track } => {
  track.at(0).play(quarter.note('kick'));
});

Play multiple notes at once:

session.track('drums', ({ track } => {
  track.at(0).play(quarter.note('kick snare ride'));
});

Play a phrase by name:

session.track('drums', ({ track } => {
  track.at(0).play.phrase('beat');
});

Define and play a phrase:

session.track('drums', ({ track } => {
  track.at(0).play.phrase([
    quarter.note('kick'),
    quarter.note('snare'),
    quarter.note('kick'),
    quarter.note('snare'),
  ]);
});

Set track volume in dB.

session.track('drums', ({ track }) => {
  track.at(0).volume(-10);
});

Set track panning (-1 to 1).

session.track('drums', ({ track }) => {
  track.at(0).pan(-0.75);
});

Mute the track.

Examples

Mute track at measure 5:

session.track('drums', ({ track }) => {
  track.at(5).mute();
});

Mute entire track:

session.track('drums', ({ track }) => {
  track.mute();
});

Mute for first 10 measures only:

session.track('drums', ({ track }) => {
  track.at(0).mute();
  track.at(9).mute(false);
});

Select a position on the timeline by measure, beat and subdivision.

Positions begin from 0, meaning that "measure 1, beat 1" in spoken word implies "measure 0, beat 0" in Harmonicon.

Examples

Set tempo to 120 at the beginning of song:

session('my-song', ({ session }) => {
  session.at(0).tempo(120);
})

Play a C# on beat 2 of measure 1:

track('my-song', ({ session }) => {
  track.at(1, 2).play(quarter.note('C#'));
})

Trigger multiple actions at the same position:

track('my-song', ({ session }) => {
  session.at(0)
    .meter([ 4, 4 ])
    .tempo(120)
    .key('C')
})
