The NotePlayer Component

The LightSensor component provides a simple interface for playing musical notes, allowing dynamic loading of instrument samples and triggering notes.

Creating a NotePlayer Instance

To create a new instance of NotePlayer:

const options = {
    A1: "https://tonejs.github.io/audio/casio/A1.mp3",
    // Add more notes as needed
};
const player = new Protobject.NotePlayer(options);

const player = new Protobject.NotePlayer(options);

Alternatively, you can pass a single URL string as options:

const singleNoteUrl = "https://tonejs.github.io/audio/casio/A1.mp3";
const player = new Protobject.NotePlayer(singleNoteUrl);

Loading the Instrument

The instrument samples are loaded asynchronously.

player.onInstrumentLoaded(() => {
    console.log("Instrument loaded successfully.");
});

Playing Notes

To play a note:

player.play("A1"); // Play note A1

You can also play notes by frequency:

player.play(440); // Play middle A

Stopping Playback

To stop the currently playing note:

player.stop();

Handling Instrument Loading Completion

To execute code once the instrument has finished loading:

player.onInstrumentLoaded(() => {
    console.log("Instrument loaded successfully.");
});

Example Usage

const options = {
    A1: "https://tonejs.github.io/audio/casio/A1.mp3",
    B1: "https://tonejs.github.io/audio/casio/B1.mp3",
    // Add more notes as needed
};

const player = new Protobject.NotePlayer(options);

player.onInstrumentLoaded(() => {
    console.log("Instrument loaded successfully.");
    player.play("A1");
});
