I own the BK-9 and recently started tweaking my registrations again after after my initial set up. I compared it with the S-910 I had, and found that it was not balanced and gig ready as was the Yamaha. Being thusly spoiled,I was somewhat disappointed that Roland had not gone a step further. One can argue and say that it up to individual taste. This is true after it is at least minimally optimized.

On the other hand, the BK-9 has so much going for it, like great key bed,killer B-3,76 keys,16 lbs,great styles, and very realistic sounds, of which there are a great many. The two small screens,at first, seemed like a throwback from the past,but, they are very useful and well integrated to reduce searching for parameters.

I am now working on it again after learning more about it. It is very simple to balance with the mixer window and it is approaching my expectations.

I agree that it is a shame that it didn't sell as well as it should have. As for me, instead of buyers remorse, I am thankful that our friend Diki encouraged me to hang in there, because it is a great board for gigging.
