What is a MIDI Song
MIDI Songs’ jargon name is Standard MIDI File, often abbreviated as SMF.
The filename extension is .mid. The Standard MIDI File is the industry stan-
dard format for songs, and is used by Pa4X as the native file format when
playing and recording MIDI Songs.
The MIDI Karaoke File (.kar) is an extension of the SMF format, and is also
supported. It always contains lyrics.

What is an MP3 Song
MP3 Songs’ real name is even funnier: MPEG Layer-3, usually abbreviated
as MP3. The filename extension is .mp3. This is a compressed audio file,
used to store recorded songs in the smallest amount of space, without
losing too much audio quality. At the highest quality, MP3 files are usually
impossible to distinguish from a non-compressed audio file. Pa4X can play
and record MP3 files.
