Thanks all for your responses. I used Korg's style program and it seems to work well. I created a style file based on a song that I created a few years back with little problems. I only created two variations for now, but yes the good old cut and paste trick works.

I still have to do some tweaking within the PA80, but over all I was able to create a style from MIDI and load it into the PA.

I will also download the KAT2000 trial versin and play around with it.
