I have a friend who is going to buy a PSR3000 or a Tyros 2. He is mainly interested in an arranger keyboard to play styles (mostly in a studio). He will use an 88 note controller with various sound modules and soft synths for solo voices and to control the arranger. Are all of the Tyros 2 styles available on the PSR 3000? How do they sound on the PSR3000 compared to the Tyros 2? If you were intersted in only the styles, which would you buy? Thanks in advance for your response.
