How to open .MID files on iOS
To open .MID files on iOS, in the Files app, tap the .MID file and use Share/Open in to send it to a MIDI-capable music app; if preview fails, import it into a DAW-style app on a desktop instead.
Step-by-step instructions
- In the Files app, tap the .MID file and use Share/Open in to send it to a MIDI-capable music app; if preview fails, import it into a DAW-style app on a desktop instead.
Common issues
It opens but sounds different than expected
.MID files contain performance instructions, not recorded audio; the actual sound depends on the synthesizer, sound set, and instrument mappings used by the player/app.
- Open the file in a DAW and assign your own instruments (software instruments/synths) to the MIDI tracks.
- Check program (instrument) changes and channel assignments; adjust them to match the intended sound set.
- Try a different MIDI-capable app or device if the current one uses a limited or different sound bank.
The .MID file does not open or import
The app may not support Standard MIDI Files, or the file may be incomplete/corrupted.
- Try importing the file into a music production app that supports Standard MIDI Files rather than relying on a generic media player.
- Re-download or re-copy the file to ensure it was transferred completely.
- Test the file in another MIDI-capable program to confirm whether the file itself is damaged.
No sound during playback
A MIDI file can play with no audible output if there is no synthesizer/instrument assigned or MIDI output is not configured.
- In your app, load a software instrument/synth for each MIDI track or route MIDI to an external device that can generate sound.
- Verify the track/channel is not muted and that volume/expression controller values are not set to zero.
- On Linux in particular, confirm your MIDI/audio routing includes a software synthesizer (since MIDI is not audio by itself).
Security note
.MID files are generally data-only (musical events), but treat them as untrusted input: malformed files can still trigger bugs in media players, synths, or DAWs that parse MIDI.
