Bachus, when is Musik Messe 2015 taking place?

I'm curious to whether Roland will introduce a more TOTL arranger than BK-9, or, more likely, have 61-note versions of it.

I think a replacement for Yamaha S950 is the more likely, with the new CVP coming out a bit later, but, of course, maybe there will be nothing new.

This iPad arranger looks interesting...any more information on it?
