Questions
Is MIDI Player free?
Yes. Every feature is free, including loading your own SoundFonts, the falling-notes piano, tempo, transpose, loops, karaoke and WAV export. The app shows ads, but never while music plays and never on top of the piano.
Can I use my own SoundFont (.sf2 or .sf3)?
Yes, for free. Open Settings, tap Add your own SoundFont and pick any .sf2 or .sf3 file up to 200 MB, or share it to the app from Drive or Files. You can keep several and switch between them.
Which files does it open?
Standard MIDI files (.mid, .midi, format 0, 1 and 2), karaoke files (.kar) with lyrics, and RMID (.rmi). SoundFonts in .sf2 and .sf3 format.
Does it keep playing with the screen off?
Yes. Music continues in the background with controls in the notification and on the lock screen, and a playlist or queue moves on to the next song by itself.
How do I open a MIDI file from Drive, Discord or email?
Tap the file, choose Open with or Share, and pick MIDI Player. You can also tap Open MIDI file in the app. No storage permission is needed.
Can it slow a song down for practice?
Yes. Tempo goes from 25% to 200% without changing the pitch. You can also transpose, loop a passage from A to B, and mute the right or left hand to play that part yourself.
Are my files uploaded?
No. Songs and SoundFonts are played on your phone and never sent anywhere. There is no account.
