You can download a trial version of Styleworks 2000 from this site, http://www.stylediskwarehouse.com/styleworks.htm so you will then be able to decide if its for you or not. (It will only play GM sounds on a computer, no mater what trial version you use)
Unfortunately as far as I am aware it is only available for Windows PC not Mac.
Hope this helps.
