๐Ÿ“– FAQ

What is a MIDI file?

MIDI (Musical Instrument Digital Interface) files are not audio files but contain musical instructions. They record note pitch, duration, velocity, and instrument info but no actual sound waves. MIDI files are very small and need a synthesizer to play.

Why does MIDI sound different from the original?

MIDI only contains instructions, not actual sound. Playback depends on the sound source (SoundFont). Different sound sources produce completely different timbres. This tool uses the Web Audio API synthesizer with selectable instruments.

What MIDI formats are supported?

Standard MIDI files (.mid) including Format 0 (single track) and Format 1 (multi-track). RMI and KAR formats are not supported.

Are MIDI files uploaded to a server?

No. All MIDI parsing and playback is done locally in your browser. MIDI data never leaves your device.

Can I adjust playback speed?

Yes. This tool supports 0.25x to 4x speed adjustment for slow learning or quick browsing. Speed changes do not affect pitch.
