Agree Chas.
These days I look for features that make live playing easier and/or more intuitive. They all sound good enough if you use 'em right. This one seems to offer a lot more than previous Yammys.
Right now I'm playing a EA7 I bought used (fourth owner).
The features that many want, such as 76 keys weighted keys, I can't use. I already have arguably the finest arranger ever built and I can't use it four hours a night anymore because it hurts my wrists and fingers.
So this looks tempting.
I just bought another boat today though and may have to get my wife a second job.
