Rod,

If you are considering PA80, make sure you like the way fill-ins behave. Some like it, but some don't. I don't like its behavior when playing factory styles, but I like it when it comes to user styles that are specifically created for a particular song. And the different behavior of fill-in and intro buttons, and chord variations will also come handy when creating styles.

Voice and drum kit editing is also very nice.
One can learn the OS for programming and editing. But when I plays live, some behavior of PA80 become annoying. e.g. To stop the acc and bass and play only the drums I have to push buttons: once to stop once again to start. On a Yamaha, you stop it from the keyboard and it synch starts when you hit the chord again. It's much easier; don't even have to take the hand away from the keys.
