Hey Diki. Agree. I was amazed when I took the BK out of the box - so manageable. In comparison to my FA-07, the BK keybed is much better. The FA keybed is not fun to play, as it is hard to engage the key (so stiff). Not the same on the BK (awesome). The 4X must use a different keybed (Fatar? - dunno) and is much better than the BK (IMO). But........I still really love the BK bed and look forward to seeing what the crowd thinks about it - the real test!
