Hey Mike ,

I tried 4.0 at NAMM and was very happy with the new developments .

14 disk are needed to upgrade the SD1 up to 4.0 .
Save all new information onto a folder of the hard drive . Call up the folder and load all new data from the hard drive .

You will get ............
Improved electric pianos
Improved organ sounds
198 improved styles ( all X1 styles carried over to Sd1 ) and brand new styles .

You now have the ability to isolate any part of a style in real time . Kind of an "unplugged" feature for styles .

With the new OS ,loaded styles are easier to call up and access . All additional patterns/styles are stored on a master folder of the hard drive , giving you access of up to 999 styles at any givin time .


Drum and bass feature is now assignable to the footswitch .

Great improvements !

That's all I have time for right now .
