Steve, it looks like you're far ahead
But to be honest, when a grown up Korg has replaced my KMA, I think it's the finish line.
Genos, + TOTL Korg, BiaB and the BK7-m will keep me busy for the rest of my life.
The only thing to fullfill, most be something to play all my old Technics and Ketron stuff.
Maybe a sxKN2600 and a SD module will be enough to close the run....
We'll see, but Dan have a software arranger named vArranger too ....
