Waiting on details of the chord recognition modes. I must admit, the Pianist2 mode on the BK series is a huge step up from the traditional ‘3 notes down before a new chord’ which is still the standard for most brands’ pianist system.

The addition of ‘5 notes down before a new chord while the sustain is down’ makes all the difference for the average pianist, allowing much more freedom before the chord recognition freaks out. And without dedicating another pedal to chord recognition on/off which isn’t really how pianists play.

Be interesting to see if the Roland has borrowed some of that new Yamaha system that looks at velocity or note density to automatically bring in higher Variations. I heard some demos of the Yamaha and wasn’t really convinced it was quite perfected. Only two Variation without at least something adding to that is a bit of a turnoff, but then again, pianists tend to need much simpler accompaniment, being used to playing everything in the first place..!
