Digital Sound & Music Interface for OS/2

------------------------------------------

DSMI/2 is a sound interface for PC compatible computers running on IBM's
Operating System /2. It goes way beyond the basic sound functionality
offered in OS/2 via MMPM/2 and provides programmers with a variety of
functions to play music and sound effects in their programs.

DSMI/2 will be most useful to multimedia applications and game developers.
It is also very well suited for network audio applications, such as
Internet applications.

Proven technology --------------------------------------------------------

DSMI was created by Otto Chrons of Virtual Visions Finland and originally
came out on the DOS platform in 1991. It is constantly updated as music
technology evolves.

DSMI for OS/2 was developed by Julien Pierre and released fall 1995.

DSMI is best known as the heart of Dual Module Player, a very
popular music player program for DOS and OS/2.

Among others, DSMI is used in Disney Software's Aladdin and Lion King
games for MS-DOS.

On the OS/2 platform, over 4500 have downloaded the DSMI plug-in
for Navigator from the official DSMI plug-in site.

DSMI/2 is also used in Flight for OS/2, a multimedia demonstration
developed jointly by Egerter Software, PolyEx Software and Julien Pierre.
