Open MID, MIDI and MDI files
Use Open MIDI or drag a file into the page to see its notes and hear the song. Files ending in .mdi are accepted when they contain standard MIDI data; renaming a PDF or image does not turn it into MIDI.

Keyboard range not set. MIDI notes 0–127 are still accepted.
Connect your keyboard using a USB data cable, press Connect, and allow MIDI access. Select its MIDI input; DAW ports control music software. If pads trigger unwanted notes, choose the keyboard channel shown next to the last note. For devices sending note-on/off on different channels, use Compatibility release. Settings are remembered for each keyboard in this browser.
How to play a MIDI file online
- Choose Open MIDI and select a .mid or .midi file, or try a demo without signing in.
- Press Play to hear the song and watch the notes fall onto the 88-key piano.

Practice at your own pace
The piano displays 88 keys from A0 to C8. Slow down a passage, loop A–B, choose a hand or track, or use Wait for notes to continue only after you play the expected notes. Adjust the sound, volume and virtual sustain pedal.
Connect your MIDI keyboard
On a browser that supports Web MIDI, connect your USB keyboard, press Connect MIDI and allow access. Launchkey and other MIDI keyboards can use their own key range while the screen keeps the full 88-key piano.
Keep your songs across devices
Sign in to save uploaded songs in your private library and open them again on another device. Free accounts include 40 MB. Optional 1 GB, 2 GB and 3 GB plans are shown under Storage plans with the prices configured by the site administrator.
Does a MIDI file contain recorded sound?
No. MIDI stores notes and timing rather than an audio recording. PianoDrift plays melodic tracks with your selected sound, so a multi-instrument file will not sound like its original arrangement. Drum-channel notes are skipped.
Which MIDI files can I open?
PianoDrift supports standard MIDI formats 0 and 1, up to 32 MB per file. Format 2 and SMPTE timing are not supported. A PDF, image or MP3 must be converted to MIDI with another tool first.
Do I need an account to play?
No. You can open and play a local MIDI file without signing in. An account is needed to store songs on the server and access your library from other devices.
Is this sheet music recognition?
This player reads MIDI data. It does not automatically convert sheet music images or scanned PDFs into MIDI. Convert those files to MIDI first, then open the result here.
