Usage

Start and stop notes

Start function accepts note name, midi number or object:

piano.start("C4");
piano.start(60);
piano.start({ note: "C4" });
piano.start({ midi: "C4" });

Start function returns a stop function:

const stopNote = piano.start("C4");
stopNote();

You can stop all sounding notes at once:

["D4", "F4", "A4"].map(piano.start);
piano.stop();

Schedule

You can pass an optional time to note object:

const now = context.currentTime;
piano.start({ note: "C4", time: now });
piano.start({ note: "E4", time: now + 0.5 });
piano.start({ note: "G4", time: now + 1 });
