There are plenty of USER demos of the T3, PA2 etc. which blow this away. Don't blame how it SOUNDS on your playing. I am capable of hearing the difference. The style section is very apparent and separate from the RH voices. And THAT is what I'm listening to. Go and listen to the Tyros STYLE demos, will you?
No amount of skill (or lack thereof) can change what the style section does. You put down a chord, it plays what it plays. OK, OK, you can screw up the chords, but big deal! It still plays what it plays. Judge an arranger on this feature ALONE. Plenty of VSTi players, WS's, groove boxes, etc. out there, but an arranger is an ARRANGER. You judge them on the strength or weakness of the accompaniment system.
You honestly think this compares to a TOTL closed arranger?
