Hi is there a way of converting my technics6000 disks to be able to load them and use on my dads ga1 organ.

Hi, I am sure even if you could change the Hex codes on the discs the problem is the KN6000 is from 1999 and the GA1 is from 1994 and as Technics software is only forward compatible,let alone trying to cross load from product ranges.I know that later models of KN and PR ranges share software check (www ca-software.com/technics/downloads/index.htm)
One thing you can try is to format a disc on the GA1 and use a pc to transfer a .cmp file from the KN6 on the disc and see if you get any response when you try to load in the GA1 but I would not hold my breath ! but it might work. Let us know how you get on.
Regards John.

I agree with John, it won't work.
