I don't understand this problem (yet), because I am using cakewalk Deluxe Pro Audio 9 to record a couple of songs. My Tyros did not freeze up. I did have to make some adjustments in cakewalk, but they weren't anything that I now remember so could only have been normal resulting in switching keyboards.
I think the biggest change was downloading and installing an instrument defination file that someone was kind enough to post on either this or the GA forum.
