I wish I was at Oostendorp, too!
Thanks for your detailed review. I'm glad the sound got better than the previous model.
I have a question: I don't know if you've ever tried the PSR-S970, but in case you did, how did it compare to the Pa4x sound-wise?
If an S970 is a Tyros witouth SA2, ensemble and ORgan world sounds(which it is), i would say it follows closely behind the PA4x.. But then, these days all arrangers sound great... and one would buy a new arranger based on features, UI, and mostly budget..
