The Pro,

I have several questions to ask:

1) If one does not tweak any sound but uses only factory sounds, what advantage does Motif ES (other than the keyboard feel) over Tyros? I am selecting Tyros here for comparison because they share the sounds.

2) Does the phraze factory functionality offer anything that an arranger (say Tyros) will not be able to do so?

3) You already own PSR9Kpro. Do you see an advantage in sounds?

4) What are any distinctive features for this keyboard that is not in Tyros?

The reason I am asking you this question is because I shopping for a keyboard myself. I know what I want but I need these particular questions answered.
