After leaving MIDI, the receiving app must support the streams encoded inside MP3, not only its extension.

When does MIDI to MP3 conversion make sense?

It is useful when MIDI media created for music-event exchange must enter a MP3 system designed for easy sharing.

Where is the MIDI source processed?

The browser prepares MP3 from MIDI on this device instead of sending the source to a remote conversion server.

How can I approve MP3 converted from MIDI?

Test the MP3 file in the receiving app and compare duration, channels and loudness with the MIDI source.
