🎹 Grand Piano

Tap a key to play. The app spans C3–B5 (three octaves).

Tap a key…
Everything you need

A whole studio in your pocket

Simple enough to jam in seconds, deep enough to finish a track.

8 Drum Pads

Kick, snare, claps, hats and toms — a full kit laid out for two-thumb grooves. Colour-coded and instantly responsive.

Grand Piano

A three-octave keyboard (C3–B5) with clean, natural-sounding notes — perfect for melodies, chords and quick ideas.

Record & Playback

Hit record, perform, and play it right back. Every tap is captured with its exact timing so your groove stays tight.

Your Library

Save beats and songs, then load, rename or delete them anytime. Separate libraries keep your drums and piano organised.

Jam Over Any Song

Import an audio or video track and play along on top. Practise, remix, or add your own beat over a backing track.

Export & Share

Bounce your performance to an audio (.m4a) or video (.mp4) file with a live progress bar, then save it to your device or share it anywhere.
