The internal style files are .stx and are totally different from .sty files. However, XGworks will use .sty files quite happily. Just one thing - if you use styles converted from other manufacturers, you have to make sure that the proper Yamaha sysex is in place. Best way to do this is to use CasmEdit on a genuine style file to see what the sysex is. You can find a link on Jorgen's web site.
