I have already said I believe the BK9 is really a MOTL arranger. An upper end MOTL, to be sure, but some of the features are pretty unique, and as it is 76, if it HAD a 61 version, it would be priced fairly close to Yamaha's MOTL S950.
I am not sure why people want to compare the BK9 to a T4. Unless they want to make themselves feel better as a Yamaha user!
Mind you, let's face it... Is what you get (or far more to the point, what you USE of what you get) worth another $2000-2500? In other words, do you get TWICE the arranger? You don't even get the same number of keys!
BTW, for all of you that have been down on 76 note arrangers because of the weight, here's one that bucks the trend. Lighter than a 61!
Overall, as far as the display goes, yes... An inferior display to Yamaha's S950. Oh, wait a minute - TWO displays

The jury is out yet on whether two not so great displays is more useful than one higher resolution color one. Particularly when NEITHER of them are touch screens. I can think of quite a few useful things I could do given a choice of
what get displayed.
I know I'm spit-balling here, but perhaps the lack of a touch screen, the lack of the high end keybed, VH, and a an extra UPR and LWR Part leave Roland with the option to come out with a REAL TOTL arranger at closer to the usual TOTL price (mind you, that would probably still be lower than Yamaha's amazingly inflated Tyros price point) if the market picks up?
And finally, nobody that researches the issue would ever consider an iPad as a viable alternative to a touch screen. Roland's software is barebones at best, and not a substitute in ANY sense of the word for a real touchscreen.
Meanwhile, of course, the BK's still have a punchy, live sound that even Yamaha's inflatedly priced TOTL arranger can only dream of.
