Hi Mike. Yes unless my memory serves me badly. With the exception of the KN2000 all of the Technics keyboards were designed to pass their style files on up the range (compatibility) but not the other way...so for example you can pass Kn7000 style files to the KN2600 and KN2400 but you cannot pass the KN2600 and KN2400 style files backwards to the KN7000.
I can remember downloading KN1000 style files from Gunnar Jonny's web site and using them in my KN7000. However memory fades with age...chuckle, and someone else might be able to contradict me.
Only one other thing I would add, and that is when taking style files from the KN1000, or any other earlier Technics keyboard such as the KN3000 or KN5000, it is important to first transfer them in the KN1000 to memory load 'A' because that is what is being saved to floppy disk.
