Package Exports

@ondas/piano/dist/index.mjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ondas/piano) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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 });
