...OK but as has been said on another thread on this forum, You will not get what you are suggesting for £2100 ! I agree, that there is certainly room for improvement in the sounds and that applies to all arranger keyboards that I have heard, but there has to be a reasonable cut-off point.
There are many people very satisfied with most of the sounds and facilities offered by the KN range of keyboards, they can't all be wrong and tone deaf
We don't all have the funds to be able to afford the ultimate in musical instrument reproduction and even if we did, I for one would not wish to carry a whole load of different pieces of equipment to a gig, for just a small improvement in sound, which would most probably not even be noticed by the audience.
