Hi Mike
Here are some links http://www.wersi.net/ http://www.wersimusic.com/ http://www.harmony-music.co.uk/wersi.htm

Have also uploaded some info here (The usual site is down at the moment) http://rapidshare.com/files/8414596/OAS_Details.pdf.html http://rapidshare.com/files/8414597/World_of_OAS_1.pdf.html

The full details of the Open Art Arranger are not out yet, but one of its features is the Direct Play of all Yamaha styles without conversion
You can also have a look at my web site that I am slowly building www.wersiabacus.plus.com

Hope this helps

Bill
