Scores

Scores lets you to schedule a note on a particular "channel". Then use Tone.Note.route to listen for events on that channel. Multiple notes can be put into a JSON-friendly score which can be parsed using Tone.Note.parseScore.

Take a look at source to see the score format. MIDI files can also be converted to JSON score format using utils/MidiToScore.js.
