Well I thought I would share my experiences using these for 3 years now.
These are great for keyboardists who are in need of 88 keys, which I feel are crucial personally.
They have the best contoller features available if you are using synths or need to mix live. The drawbars are cool, but hardly useful since they are too far apart to emulate the drawbars of a Hammond. But alas no fear, I actually tie different drawbars of my B2003 to a single fader for the basic swells, etc, the other faders can be used as AUX's, channel or master faders of a mix.
However, I have now got broken contacts on each keyboard. I thought the first one was just a sparse incident, when actually it is the keybed design, which is cheap.
But I do 2 gigs daily and practice, so I have played many, many hours on these.
For 360 shipped though, I shall just go buy one more. I was using 2 of these, but will have my hardware Solaris synth within a month, so I'll grab another one since I find the MIDI controller features of this ax to be supreme.
If you are interested in these keyboards this may be of some concern, but IMHO at the price it costs, and ease of use, you only need ask yourself if it's suitable.
Personally these are rugid built as I move them nightly, well one of them. The other stays at the gig, and I don't even case it up. I figure if some jerk off steals it, he can pack it up. I'll just drive to the generic music store ( Guitar Center ) and buy another.
I am always on the look out for a great controller and will be demo'ing the VAX77 at NAMM in Janurary. They are close to the Solaris/Soniccore booth where I will be, and a Waldorf distributor is also close. Nice, lot's of synths.
Not dissin' the KS88, just stating fact.
Now I will buy another one of these cheapo crapwagons.
