Hi Taike.
I've seen the Kawai organs on the Japanese site but I have not been able to find any demos of them. Do you happen to have a link at all or any information as to this DVD?
It does look one hell of an amazing instrument from the specs, but getting one into the UK would be as hard as getting blood out of a stone. Why do companies make it so hard for people to purchase organs these days. Stage EA, D-Deck, new Kawai all just about impossibe.
