It features falling notes visualization at 60fps, a Wait Mode that pauses until you press the correct key, real-time practice scoring, advanced metronome with accent patterns, chord detection, and supports 8 languages. It runs entirely client-side as a PWA, meaning it works offline after the first load.</p> <p>link: <a href="https://www.roxypiano.web.id/" rel="noopener noreferrer">https://www.roxypiano.web.id/</a><br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fiyj26qyc3j1t4oy491bo.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fiyj26qyc3j1t4oy491bo.png" alt=" " width="800" height="610"></a></p> virtualpiano piano javascript
