The DownLoadable Sounds (DLS) file format was firstly created by Interactive Audio Special Interest Group (IASIG) in 1990 and continued by MIDI Manufacturers Association (MMA) later. The file doesn't store music, but it does contain the digital audio samples for instrument collections.

Some audio hardware has native DLS support for wavetable synthesis, for example:

Since not many sound cards have native DLS support, Microsoft has developed DirectMusic Synthesizer, firstly bundled with DirectX 6.1, which uses DLS sound banks by design. Also the DirectMusic proprietary format was created to extend MIDI capabilities.

Mainly DLS is used in music formats like RMI or SGT, but some games can use it to store sound effects.
