Hi Lee,
can only compare keybed to my ex psrs 950, it is better. Has a better feel and not as clunky.
I’ll try and check out some voices for you.

I did download a Symphonic Yem pak yesterday, haven’t tried it yet, not even sure what’s on it, but it was free from Yamaha Website. It may only be styles, not sure.
