I don't know what limitations you were referring to on your 740. As far as styles go, factory made styles are ususally excellent, sometimes better than the internal styles that come with a synth. They are professionally produced and made by professional musicians hired by synth manufacturers.

There are also many thousands of styles available by trading with other users on the net. Many of these are just as good as the "commercial" styles. There are also lots of niche styles (i.e., ethnic) that manufacurers don't bother with for a mass audience. These are my favorites!

If your synth has a floppy or disk drive, as far as styles are concerned, there are really no limitations.
