Can I convert .smf files directly to .mp3 format?
We are not aware of any possibility to convert SMF Standard Midi Files directly to MP3 Audio Files (.smf to .mp3 conversion).
Since SMF files are essentially MIDI files, you can try renaming your file's extension from SMF to MID, in order to try a MID to MP3 conversion.
At this moment, we do not know any audio editing software or conversion utility capable of working directly with SMF files and converting them to MP3 format.
The database currently does not contain any smf software converter.
