It has been said that the keys are better; I hope not TOO much better.
This one seems to have the features I use a lot on Korg and Roland, with the weight right and price will be reasonable.
I was disappointed that no Audio styles were included, but I confirmed that it will play them, and they are readily available.
My USB stick is fairly current and should work fine until I get up to date with the new styles and sounds if necessary.
Although I like EA7 a lot, this will let be do away with the outboard vocal processor, laptop and a couple of power supplies, as does the Korg PA4X.
The 4X is getting lonely over in the corner. It technically still belongs to my friend DickeT and he will no doubt be a little disappointed to learn of the new PSR. He has worn the keys off his old 950 and will want one of these for sure.
We may have to sell his 4X now. It is like new as he never used it on a job and I have had it for the past year and haven't moved it but a dozen times or so. It has rested in my office most of that time. I do use it occasionally still and have it totally updated and loaded with "stuff".
