shakeel,
I guess you've got my reply to your e-mail already, and the site Don gives you here, is a good search to start.
Here at SZone there is also some activity:
http://www.synthzone.com/cgi-bin/forumdi...=100&LastLogin= Technote have a lot of software, so has many, many others, such as Neil Blake, CA Software (all for free), Carillon studios etc, etc.
Also you'll find some stuff at my website, and a lot of links to explore.
You can also use KN5000 or lower styles, but might have to adjust some settings.
KN6500 is a great keyboard, just as many other top range keyboards, and I'm sure that you'll find find it as a very good choice.
Good luck.
Kind regards
GJ
