I was impressed with many of the styles; they sound fresh and last more than just four bars and this adds to the overall sensation of realism. The interesting thing is that almost all the styles demoed are present also in the BK7-m, that at this point looks more and more interesting as a backing unit and would make a nice addition to one's existing setup. As for the BK-9, I hope that it's an intermediary step towards a future TOTL arranger, that has styles as fresh and live as these plus (almost) all the supernatural voices found in the Integra module and a keybed a la G-70. THAT would be a killer arranger.
