Hi,

from whatever videos i have seen, the BK 9 is far more superior to S750 or 900. It is the best arranger for a solo-player/recordist, given its 76 keys, and 3 RTs.
i have checked the schedule witb Roland's biggest distributor in India, and the sad news is that i need to wait till October to put a hand on it. Whereas the 900 is already available for import on a "pre-payment" basis.
