Beatmaster,
BK7 is a solid machine... But it is a mAcHine and a bit clunky one too.
As Mike above mentioned, "Menu takes a bit of getting used to"

I had it for two days, then it went back to the store... I do not usually return items in such manner. Please do not get me wrong, it is a neat piece of gear if you can get it at low price.
I do prefer vArranger for this arranging functions and Halion or a tuned SF2 sound bank for tones. More flexible.
