How to play MIDI files online
Choose a .mid or .midi file and this MIDI file player reads it locally, then prepares the song without uploading anything. Press Play for normal playback, drag the timeline to rehearse a precise moment, or change the speed from 0.5× to 2× while the pitch stays stable. The effective BPM updates beside the tempo control so you always know the current practice rate.
Set A and B around any passage to repeat it continuously. Multitrack files expose every part separately, letting you mute accompaniment or solo one instrument without changing the original MIDI file. These controls make MidiGlow useful for practice, arrangement checks, transcription, and quickly hearing a MIDI file on a device with no music software installed.
Keyboard shortcuts
Once a file is loaded, you can drive the whole player without touching the mouse:
| Key | Action |
|---|---|
| Space | Play / pause |
| ← / → | Seek 5 seconds back / forward |
| ↑ / ↓ | Speed down / up one step (0.5× – 2×) |
| L | Toggle the A-B loop on / off |
| R | Back to start |
Shortcuts are paused while your focus is in a field, a select, or on a button.
