Free online MUSX to MIDI converter

Use MIDI when a Finale score needs to be played or edited in a digital audio workstation, keyboard, or other software that accepts MIDI. Converting also makes the score’s musical events easier to exchange with music-production tools, though MIDI does not preserve the printed page.

What the MUSX format is

.musx is the native score format used by MakeMusic Finale. It stores notation and score-related data, and is commonly encountered in Finale projects shared by composers, arrangers, educators, and music publishers.

What the MIDI format is

.mid files store musical events such as notes, timing, tempo, and instrument-program changes. DAWs, sequencers, keyboards, and notation programs widely support MIDI, making it useful for playback, arrangement, and editing. It stores performance data rather than a complete engraved score.

Online on 101convert.com

1. Upload the MUSX file or files to the converter.
2. Run the conversion.
3. Download the resulting MIDI file or files.

The page supports batch conversion and displays a per-file size limit. Conversion runs on the service’s server with denigma, then MuseScore.

Offline with desktop software

MuseScore 4.4 or later (Windows, macOS, and Linux) can import Finale MUSX files. Open the file with File → Open, then use File → Export and choose MIDI as the output format. If MuseScore cannot read the particular MUSX file, try opening and exporting it with Finale instead.

Finale (Windows and macOS) can export its own scores directly: open the MUSX file, choose File → Export → MIDI File, then select an output location and save.

Quality and limitations

MIDI preserves note and timing events, but not page layout, staff spacing, fonts, or other engraving details. Instrument sounds are not embedded; playback depends on the MIDI program assignments and the receiving device’s sound bank. Importing a score can also alter notation or playback details, so check the exported file in its destination software.
