Hello Giovanni and Roger,
Thank you both for your replies. It sounds as though it's a lot of time consuming work and as you both know, I'm already 'cheesed off' with the amount of 'tweaking' necessary to get the Tyros3 to my liking, so on second thoughts, I'll not be going down that road. Best keep my KN7000 - then I'll always have the originals to use.
