On my old PSR-2700, style making was very primitive as compared to what we have now...it was the first keyboard I made custom styles on to any degree, mainly because I could save to floppy disk.

The only way then was to either play in the parts live, or play them in step mode, picking from a menu of note values.

As DonM said above, back then there were very few available styles (I didn't have Internet then either), so you were pretty well forced into making your own from scratch.

The first styles I saw on line were by Simon Williams of SVP World, and although they were mostly nicely done, they didn't cover the genres I needed.

My PSR-8000 and PSR-2000 had wear marks on the buttons from me making styles on them, as it was finally possible to use Style Assembly.

Nowadays, styles aren't as much of an issue, although it still is nice to edit and put your own stamp on them (and your music).
