There are 2 SMUS players on this disk, one ending in "_safe" and one ending in "_extra". The "_extra" version is a more relaxed interpretation of the SMUS IFF music format, the documentation of which is very vague in certain critical aspects. In general, use the _safe version if a song contains instruments that sound funny when played by the _extra version. These SMUS players do not necessarily represent the most up to date versions available; indeed, it seems there is always room for "one more improvement" when it comes to Amiga sound software. USAGE : smus3.5_extra iff_file instrument_dir Example : smus3.5_extra bomba df1: This will play the SMUS file "bomba" (available in Deluxe Music Construction Set) in the current directory with all available instruments in the directory "DF1:Instruments". These players are for demonstration purposes only; the actual device device drivers are available for licensing to commercial developers.
