In my ears Genos sounds better than my T4, seems like they somehow made it sound less CD'ish.
It's an eyecandy, and screenshots of the touchscreen layout looks nice.
Not gigging anymore, and as "only a homeplayer" this is the first Yamaha kb that really ever tempted me.
T4 was bought mainly because of the huge stylelibrary out there.

Now I have some thoughts about Genos versus PA4X/76. It's a big gap in price, and is it worth it for my use?
Just before Genos was launched, I was close to buy Korg.....
Darn, maybe buy both .................
