Pro Piano Ultra was born from a simple idea: an online piano should be powerful, beautiful, and respectful of your privacy. We are a small team of passionate developers, musicians, and open-source enthusiasts who believe that creative tools should be accessible to everyone without hidden costs or creepy tracking.

We built this piano because we were tired of web apps that collect data, limit features behind paywalls, or simply sound terrible. Our goal is to provide a professional-grade musical instrument that runs entirely in your browser — with 128+ unique instrument voices, a 10-band EQ, stunning visual effects, and full customization options — all while keeping your data on your device where it belongs.

🎨 Unlimited Customization

Change the color of the piano body, white keys, and black keys — instantly. Choose from 12+ glowing visual effects, from Rainbow Wave to Fire Ember to Aurora. Shape your sound with a professional 10-band equalizer. Every setting auto-saves locally, so your perfect setup is always ready when you return.

🔊 Maximum Volume, Pure Sound

We use high-quality FluidR3_GM SoundFont samples, loaded directly from the MIDI.js SoundFonts project. Our audio engine is optimized for low latency and rich, expressive tone — whether you're playing delicate classical pieces or thundering rock chords.

🔒 Privacy First, Always

We don't collect any personal data. No analytics. No tracking cookies. No server-side logging of your playing. Your preferences stay in your browser's localStorage. Your recordings stay on your device. Your music is yours alone — we never see it, hear it, or store it.

We stand on the shoulders of giants. Pro Piano Ultra would not exist without the incredible work of the open-source community.
