Gregg,

I think the most important thing to understand and also to master is the performances.

There are real-performances, style performances and song performances. Those confused me big time and I thought they simply added more overhead.

However, a friend of mine has WK4 (the same idea as SK880) and he played several tunes for me and was able to use the style/real performances in such a way that elevated his music big time.

The way he was using those performances to switch between styles, sounds, configuration convinced me to pay more attention to performances. He is a live-performer and it is working for him very well.
