Simon. For me they have a cheap soft feel, not much better than the 2000\2100. I thought you previously had a 9000Pro in which case you know what I mean. Taking in the price of the Tyros they could have supplied a better quality keyboard (afterall you have paid for one) to the standards of 9000Pro. & VA76. I play a Tyros twice a week and its a relief to get back to my 9KPro.
The new Korg 76 keys PA1X is excellent, that's not to say the 61 note version will be as good.
