Kidd,
Your Korg PA800 can record style in real time as well. I believe Korg calls this "Backing Sequence mode."
Unlike most other makes, Korg allows you to use step mode to correct mistakes made recording with styles in real time. If you play an incorrect chord for example, the error will be reflected on most of the accompaniment tracks. You can just go to the "chord" track in step mode and change the chord/bass to what it should have been. The Korg will automatically generate a new accompaniment (full midi) with the correct chord data!
