Not sure if this has been posted previously. The BK-9 is definitely a gig worthy arranger. After listening to some of these latest demos I would have to say the BK-9 is every bit as good as any other high-end arranger currently on the market. It has shortcomings like the low resolution, monochromatic LCD screen(s). But if you can get past that obviously planned oversight by Roland - wanting you to buy a $500 iPad to see things in color - then the BK-9 might just fit the bill. Enjoy...
