You're quite right. A family friend who sold us his KN6000 now has a Tyros. I've had the chance to try it on more than a few occasions. It has made me appreciate not only the capabilities of the 6000 but also the simplicity of it's operation. Looking at the Tyros, there are just too many damned keys and they don't appear to have been arranged in an particular order. You only have to look at the instruction manual, lord it's three times at thick.
No, I think the best advice is stay with Technics. If for no other reason, I'd prefer to spend 30 minutes setting up the KN for a performance rather than 90+ on the Tyros.
