"15) The Tyros loads & plays PSR2000 format Styles w/OTS, as well as
well as loads PSR2000 Music Finder files (abeit minor tweaking)"

Your #15 suggests that registrations created on the PSR2000 will read correctly on the Tyros. According to the specs I read, only registrations from the 8000 and 9000 will read correctly on the Tyros. Or did I misunderstand you?
