what is a virtual piano?

A virtual piano is a software instrument that recreates an acoustic piano inside your browser — no hardware required. Instead of hammers striking strings, it plays back high-quality recordings of a real grand piano, one for (almost) every note and every level of loudness. The result sounds like the real instrument, but lives entirely on screen.

Octype uses the Salamander Grand Piano sample library: a concert grand recorded note by note, at sixteen different playing intensities, so soft passages and powerful chords each have their own authentic tone.

how it works

01
you play
Press a computer key, click or tap a key on screen, or play a connected MIDI keyboard.
02
the engine responds
A dedicated audio engine picks the matching recorded sample, sets its pitch and loudness, and plays it instantly — with sub-10ms perceived latency.
03
it sounds real
Up to 24 notes ring at once, each fading naturally like a real piano. Sustain, reverb, and velocity bring it to life.
