I use them using BIAB direct and using the Conductor tool, which allows seamless jumps to ANY section of the song. I also use the Jukebox tool which allows the stacking of selected tunes to play at a gig.

Even though it is 100% audio (bass and drums included), the jump between parts is smooth with no audible glitching. I only use jumps if some bright spark decides they want to dance JUST as the coda starts

Sorta makes it a pseudo-arranger

All of the tunes on my SC pages were done using it. No midi at all.

So with the Audio feature of the BK - well there are possibilities in that direction.

Probs the main thing is being able to get away from using VSTi keys - if they are as good as you say on the BK.

The other thing I am hesitant about IS the keybed. The A70, though old has a lovely action (very similar, if not the same as the G70, even with the slightly concave key surface) and from what I am reading the BK bed would be somewhat of a come-down. And before you suggest it , I am NOT a twin keyboard sort of person.
