The good thing about Yamaha styles is that there is such an abbundance of styles..

But what makes sthem special to me is the special styles..
- the piano styles i converted from CVP
- the free play styles, which are unique to Yamaha
- the session styles which are much more dynamic then the stadard pro styles
(I dont think the audio styles add much, they are just good styles)
- the new deejay styles prommise to be different.
- mega voices still work great for styles

And the community is great.. Many people share the great stuff they created themselves, and there are dozens of great free tools available that help you when creating stuff.
On top of that it seems much easier to convert other brand styles to Yamaha then the other way around. the good thing when converting Korg, Roland and Ketron styles to Yamaha format is that they bring you that live feeling that the Korg and Ketron developers programmed them with..



Roland however still has the most tools to change their styles sound with just a few clicks and options to make them sound more dynamic, reacting to things like the volume of the left hand..

Ketron Audio styles are unique and not convertible to other brands..

Korg styles are well programmed. They have great guitars mode.

But in general the one with most special types of styles seems is yamaha, session, free play and Deejay seem to be setting them ahead..
