Hi Bryan

I dont know much about DJX; but I think a know a lot about PSR 740 in general and styles in details.
Take a look at my Unofficial YAMAHA PSR 740 Home Page http://home7.inet.tele.dk/js/musik/740pages

There is lots of information. Check the "Articles and FAQ" page.

Styles are actually short MIDI files, so I think that someway it must be possible to use (play / record) styles at your DJX.

If you get some usefull experience in this matter I will gladly present your findings at my page. Just drop me a mail.

The very best wishes
Jørgen
