Hi Scott,
do you know, that Roland G 70 is equipped with very short Intros and Endings (as Intro 1 and Ending 1 at Tyros)?
But about style software, the PA1 is supported much better (this brand features 4 variation styles since a long time, the Roland styles, you can buy, are with 2 variation styles).
The Roland features the excellent VK organ with mini drawbars, Korg features a drawbar organ, with no drawbars and 8 footages only (not closer to B3 as the Tyros). Roland features special accordeon voices.
The Korg's vocal harmonizer is much better as the Tyros' one, the Roland's is as the Discover's one and as the Yamaha's one.
I would say, a Roland G 70 could be a good choice and hope, Roland US recognizes the existence of G70 instead to say "The VA-76 V-Arranger Keyboard is Roland's flagship intelligent arranger..."
Aha, american arranger keyboards user have no need for the latest technology?
Korg is able to sell the PA1X in the states, Yamaha is able to sell the Tyros in the states and Roland think, the Americans need arranger functions in expensive home instruments, cheap toy instruments or yesterday's top arrangers.
Well, Italy is far away from USA. ;-)
