Mod files all contain sound samples, but also have many limitations
compared to the MIDI alternatives (e.g. polyphony and sound quality). 

Standard MIDI Files do not contain sound samples, but variants such
as RMID files and certain XMF files do. It takes some work to be able
to distribute and then playback MIDI files with custom sound data, but
it is not impossible. For example, Apple and Windows operating systems
come with MIDI File playback engines that use replaceable sound sets
(in MMA's DLS format).
