Gunnar,
one more reason why I would choose the PA2X is that it makes also for a perfect master keyboard (at least compared with the other TOTL arrangers).
You can control up to four external units (assigned to the Lower, Upper 1, Upper 2 and Upper 3 parts) and send bank and program changes to four different midi channels. The coolest thing is that you can store these settings in your Songbook, so every time you call a different entry or song you have all your modules set up to play the right sounds at the right volumes...and the same thing applies for all the parts of a style: don't like a Korg drumkit or bass? Just use an external one!
This keyboard is so deep that, after ten months with it, I have learned maybe one fourth of what I should have...
