Kasey Keys - Piano

Kasey Keys is an 88-key piano you can play right on your iPhone. It uses a sampled grand piano and is built for speed, so each note sounds the moment your finger lands.

FEATURES • All 88 keys from A0 to C8, with chords and smooth glides • Two rows of keys in portrait, so the keys stay wide enough to play one-handed • One wide row in landscape, with three key sizes to choose from • Note names as C D E with octave numbers, or Do Re Mi • Drag the small 88-key strip to jump anywhere on the keyboard • Reference tone: A = 440 or 442 Hz, one semitone at a time • MIDI keyboards over USB or Bluetooth, with velocity and sustain pedal • No connection needed — the piano sound is built in and works offline

GREAT FOR • Finding the first note of a song, or its key • Checking how a chord sounds • Quick tuning by ear • Playing your MIDI keyboard through a piano sound on your iPhone
