Hi Tom,
congratulations on your Pro. As you can read version 1.02 is out now. Version 1.5 will be out this summer, including some new features, like being able to play all midi files in order or random. Keep checking the PK club site for updates. To your next question: yes you can delete styles that are in flash rom and replace them. You can also play styles directly from disk, which takes only a couple of seconds to load. Regarding simms? Don't have them, but there are posts further down discussing which ones will work (not all will).
Good luck and have fun,
Eric
