I'm glad you are happy with your BK-9 keyboard, Diki...I understand how you feel...I'm very content with my Tyros4.

Sorry, Ian. Hate to burst the bubble, but there's much about the BK-9 that could be improved. Now, that don't mean I'm
UNhappy with it, but I'm not ecstatic. Obviously, the loss of the touch screen is a disappointment. The loss of aftertouch is a lesser annoyance. Dropping one of the UPR and LWR Parts is a shame. Not having OTS for SMF use is a bit of a loss.
OTOH, it came to me a good $1500 less than the G70 came to me first.
It has my Chord Sequencer back
It has synced loop capabilities and WAV/MP3 playback, FAR better Hammond (the equal of a Nord, IMO), SA2 type sounds (the guitars are to die for), hugely improved drums (which were already industry leaders in the first place!), vastly improved overall sound selection, and of course, HALF THE WEIGHT!
Actually, LESS than half the weight!

But at no time whatsoever will you catch me trying to deny what faults it DOES have. And I think that's where you'll find the difference between me and some others here who cannot abide the least word of criticism about what THEY use.
