Isn't it great that all the modern arrangers give you these options. You don't have to use it but it is nice to know that you can.
That's the beauty of these
options...you don't have to use them.
I know several pros who sing (and play guitar/piano) over Wav/MP3 backing tracks (maybe even a few SZ'ers

) and they are pretty happy with having these
options, regardless of who makes them available.
I use them when doing demos, and it is always a lot of fun.
Again, the bottom line...the
choice to use, or not, is entirely up to the player/performer.
No sign of the PA-600 yet, Frans?
Any idea when you'll get it?
