I am presently rearranging all my old registrations and I am glad that I have saved the old T1 styles to my hard disk, because some of them have been heavily changed. An example is the 8 beat ballad, which now sounds completely different. So, I advice everyone who is planning to update from T1 to T2 to save the old styles to the hard disk.
