Per +++ MIDI.ORG +++ the main distinction between MID and SMF files appear to be where the file originates.

(SMF) files are typically created by a "MIDI sequencer" (software or hardware) and then played on some kind of MIDI synthesizer.
. I gather from this that SMF is somewhat hardware or software specific whereas a MID file is more device agnostic and computer orientated.

+++ THIS +++ site by the US Library of Congress indicates a SMF file can contain additional data not specified in the MID file specification.


I don't interpret that midi.org document as distinguishing .smf files from .mid files.

As I read this stuff, "SMF" is used as an abbreviation for "Standard MIDI File" while .mid is specified as the extension for this format.
