The style conversion software supplied with the 7000 has turned out to be the same formats as the 6X00, and not the new disk as was hinted as a possibility to me by the software programmer at Frankfurt.
However I have just heard from the source that the upgrade disk will be available as an option for the 7000 in a couple of months time.
To recap, the supplied disk converts
Solton MS40,50,60,100
Roland E96,86,66,G800,600, RA95,800
Korg i1,2,3,4,5
Gem WX2,400 WS2,400
Technics 750,1000
The new disk will provisionally also convert
Ketron X1, SD1, X9
Roland G-1000, VA-7
Korg i30, PA80
Yamaha including PSR9000,pro,2000 etc
