Hi Don,
I liked the BK-7M. The ONLY reason I sold it was because it did not allow users to change the OTS voices and save them. Had it allowed those changes I would have kept it. When I called Roland support they did not have any indication that any software updates were in the near future so off it went.
I am not sure I am going to be a buyer for any more $4000.00 keyboards. Right now I am very happy with my Tyros 4 and will probably keep it well beyond it's useful life. Until other manufactures develop a multitude of additional styles I will stay with Yamaha. For me that is the most important feature - availability of "free" styles.
I have tried Korgs in the past, both the PA1X and the PA2X Pro and did like the styles. Had Korg developed the support for styles that Yamaha enjoys I would have kept both of the Korgs. I believe all the TOTL arrangers are pretty good - but whichever arranger you buy it has to fit into your gigging requirements and for the working pro that is the "ONLY" thing that matters.

Latest info says there will be a big upgrade in January, correcting a couple of omissions and adding some things that users have requested. We'll see!
