I am afraid that I really have to call Roland out about the dual display...
There comes a point where, once an arranger is complex enough, you simply cannot do what you need to to it for live purposes with merely a dual screen, a rotary encoder, and a pair of Inc/Dec buttons. The BK-9 is certainly well past that point!
OK, I get it... you were trying to save a buck or two, and some flunky at Roland went 'Well, we've got plenty of the LCD screens for the BK-3/5, let's put TWO in?'. And no-one in the room stood up and told him what a moron he was! A missed opportunity, IMO.
Look at how other companies that don't have touch screens do it... they surround the screen with buttons to the left, right and underneath. This makes quickly selecting what you want to edit a snap. There are five buttons to the left and five to the right of the S950's screen (a nice high-res color one at that, you cheap SOB's, Roland!) allowing you easily to select what you want to get to. Not so with the BK-9. For every parameter on the screen, you FIRST have to scroll around the screen using the wheel to get to the parameter in the first place, THEN press the wheel to select it...
It is idiotic beyond belief. And that's just the start...
There is simply too many parameters you need to get to in a hurry for the tiny displays, and things quite important get buried in sub menus, inside other menus. No chance whatsoever of getting to them live, while you play. Even exiting these sub menus can be a pain (although a held 'exit' will get you back to the top level in one go) if you want to do something further.
Let's take a simple example. Let's say you want to change the chord recognition type from Intelligent to Pianostyle (without calling up the piano mode - let's say you want to do it on a Rhodes, not acoustic)...
First, you hit the Menu button. You'd think that the Performance edit would be the first thing on the screen, at the top, where it gets immediately selected. No... the External Lyrics on/off switch..! Who the hell messes with that, much? You have to turn the wheel to navigate down to the Performance Edit selector, and then hit the wheel to open it up. You've now got a choice of 13 pages relating to the Performance settings! Arranger settings is #7 on that list, so you have to scroll down seven pages (careful not to overshoot!), and then hit the wheel AGAIN. You now have a choice of nine more settings. Fortunately, Arranger Type is #2, so at least you can see it! so you scroll down again to that, hit the wheel again (that is Roland's idea of an 'Enter' or 'Select' button
) to select the parameter, then scroll down again until you get the Pianist mode you want (there are two).
Can you believe all that?
Do you know what I have to do from the main page on my G70 to get to the same parameter? I hit the main screen in the top left area (the 'Chord' section) and
there it is! Along with the zone and arranger hold chord, Intro ending alteration and Dynamic Arranger buttons, plus other buttons that link you directly To the arranger Options section, Melody Intelligent section, and One touch settings.
So, one hit on the G70's screen, eight separate things to do on the BK...
Rinse and repeat for nearly everything. As far as I am concerned, this is idiotic! Particularly as Roland, in their previous arranger series, had a perfectly great working touch screen system for an arranger (the E50) that was $1000 LESS than the BK-9. Admittedly it was B&W, not full color like the G70/E80, but functionally identical.
Basically, this relegates the BK series to something you HAVE to set up everything for every song in advance. Other than selecting styles and tones on the fly (it does have the 'Favorite Tones' section from the BK-3), best of luck getting to much in a hurry!
Now, I AM one of those kind of guys when it comes to my solo and duo stuff, so the arranger is
not going back to the dealers. But Roland have missed a
massive opportunity here. This is potentially, tied to a touch screen, one of the most powerful, easy to use arrangers AND live band keyboards ever made. The Hammond sim is so good, it makes it a contender against the Nord's (particularly as it does so much more than even the Stage), against Korg's stage pianos, against anything that Yamaha can muster. It's pianos are great, basically, everything in here is great. So far, no real sonic disappointments... OK, it doesn't QUITE compete with the SA2 horns and the like, but it's a LOT closer, and some of the SuperNatural stuff goes even further than Yamaha do.
This is one amazing arranger/live keyboard.
Utterly let down by the decision to shave costs by axing the touch screen, and not surrounding the main screens with buttons.
Once again, Roland show their utter disconnect with musicians that play their keyboards. And their complete inability to recognize what was BEST about previous models and preserve it as they move forward. Whoever made this boneheaded decision needs to seriously contemplate seppuku!
