This example shows the basics of using the MonoSynth class to play a series of musical notes.

MonoSynth takes an array of song data to play.

The song data is formatted like this

[
    [notePitch, noteLength],
    [notePitch, noteLength],
    ...
]

notePitch is a midi note number

Midi note numbers are whole numbers starting at 0 for a very low C, ending at 127 for a very high G You could pass a number with a decimal portion, for out of tune notes.

You can also pass 'rest', to create a rest.

noteLength is the duration of the note, in seconds.

MonoSynth will play the notes and rests in the provided array back to back.

setup() is called by p5 kick off the program.

function setup() {
	createCanvas(640, 360);

Create an instance of MonoSynth to play the notes.

	var synth = new MonoSynth();

A hardcoded song.

	var song = [
		[64, 3 / 8],
		[62, 1 / 8],
		[60, 1 / 4],
		[62, 1 / 4],

		[64, 1 / 4],
		[64, 1 / 4],
		[64, 1 / 2]
	];

Pass the song to the synth.

	synth.playNotes(song);
