/*
all you need is to write play("your_sound_file.midi",true); for loop
or play("your_sound_file.midi",false); for one time play
You do not have to use the init(...) function since it is called from the play(...) function
This script has been tested and work with Internet Explorer, FireFox and Netscape

example below :
