Keyrain: MIDI Piano Trainer

Learn piano with falling notes, using your own MIDI files and keyboard. Keyrain shows every note as a bar falling onto a piano keyboard. Plug in a USB MIDI keyboard or digital piano (or tap the keys on screen) and play along. In Wait for me mode the music stops at each chord until you play it, with the keys to press lit up, so you learn at your own pace. PRACTICE THE WAY THAT WORKS • Wait for me: the song pauses until you hit the right notes • Hands separate: practise the right hand while Keyrain plays the left, then swap • Slow it down to 50% or 75% • A–B loop: repeat the bar you keep missing • Listen mode: hear the piece with the keys lighting up before you play • An accuracy score for every run, your best for every song, and a one-tap loop of the bit you slipped on YOUR OWN MUSIC • Import any standard MIDI file (.mid) from your phone, Google Drive or downloads • Or tap a MIDI file in your file manager and choose Open with Keyrain • Two-track files split into right and left hand automatically NINETEEN PIECES INCLUDED Twinkle Twinkle, Ode to Joy, Jingle Bells, Minuet in G, Brahms' Lullaby, Amazing Grace, Greensleeves, Für Elise (opening), Canon in D, Bach's Prelude in C (opening), Gymnopédie No. 1, Moonlight Sonata (opening), Clair de Lune (opening), Turkish March, Chopin's Nocturne Op. 9 No. 2, In the Hall of the Mountain King, The Entertainer, the Swan Lake theme and Bach's Toccata in D minor (opening), in our own arrangements.
