About XMF
The MIDI Manufacturers Association published the Extensible Music Format in 2001, so a song's notes and the sounds to play them could travel as one file. Mobile XMF followed in 2004 for phones, ringtone sites sold .mxmf files, and Android still plays them.
An XMF is a tree of nodes, each with metadata such as a title or a copyright: a Standard MIDI File with the notes, and often a DLS bank with the instruments it plays. Mobile XMF holds SP-MIDI and Mobile DLS, sized for a phone's synthesizer.
Filepeek plays it with SpessaSynth: the instruments its DLS bank carries, and the GeneralUser GS sound set for every part the bank leaves out. It plays with its waveform, and Show tags gives its title, copyright and tracks.

Questions
Why does an XMF sound different from my old phone?
The phone played the notes on its own synthesizer chip. Filepeek plays the same notes with the sounds the file carries, and General MIDI sounds for any part they leave out, so the tune is the same and some instruments sound a little different.
What is the difference between XMF and MXMF?
MXMF is Mobile XMF, made for phones in 2004, with SP-MIDI and the smaller Mobile DLS sounds. Both open here.
Can I turn an XMF into an MP3?
Yes. Choose Export, then Save as MP3 or WAV, and the song is saved as it sounds here.
