Too bad Technics styles are not backward compatable, a fault of Technics, along with the default save of a sequence as a Technics file that often frustrated many. I had a KN3000 for a long time, a very rugged keyboard that gave me much satisfaction for years.
Lately buying an older board seems to be a cool thing to do, and I wouldn't mind giving it a go ...just for the fun of it.
Keep us posted...
