In 50 years of accordian,40 years of organ, and 20 years of keyboards, I have never seen an instrument as good as my 7000. I said the same of my 5000.My top end Clavinova is good as a home instrument for my wife,but the OS is cumbersome.
If you want to set up as a recording studio.All the tools are there.

You have a virtual organ, or should I say several organs from B3 to theater to mighty pipes. And with pedals, registrations for them if desired.Saying nothing of many accordians of stunning realism.

With the excellent sound system w/sub woofer,you can go to any small to medium job without all of the baggage and setup. The SD card with Favorites,medley ,sound or audio play lets you store your songs in any order. This includes Technics,midi,or even full wave performances.
For singing, the onboard system is almost as good as my harmonizer.
All of these advantages I have found in three months, and I haven't begun to really know it.

The tools and voices and parameters goes on and on.
