I really love this digital piano!
This DP is a fantastic instrument. But first let me qualify my comments.
I have played piano for over 30 years and traveled around the world playing professionally. I have been fortunate to work with some great players in many different genres of music. My love is jazz. If I had the cash, I would buy a Bosendorfer Imperial and forget it...but I have to pay off a house and you can't really lug a Bosendorfer to a gig too easily.
That said...the Roland FP7F is an excellent substitute. The positives far outweigh the negatives.
First off, I love the action. The key surface is an obvious fake ivory texture that I think pulls off the illusion. It feels good under the fingers to me.
The actual action (which is always somewhat subjective) is perfectly weighted to feel like a well-regulated Yamaha C5. It doesn't feel like a spinet. It feels heavier than that but not too heavy. (If you only play organ or synths then you will say that this action is too heavy...but as a piano player, I love this action.)
Second is the sound. I do like the sound of the SuperNatural grand. It is different than just samples. It is modeled. You will hear the difference. I couldn't afford the V-Piano but this is it's little brother...sort of. The piano seemed to respond well to my playing and I really liked the sound.
On many of the small jazz gigs that I played, the sound man would ask me what type of piano this was. Many would tell me that this was the best or one of the best piano sounds that they ever mixed. I have to add that it really sounds like a well-miked grand piano and not a digital through a PA.
As far as the other sounds, I really only occasionally use the Rhodes sound and maybe the strings layered. These sounds are very usable and pleasing to hear. Another favorite of mine is the Acoustic Bass. It isn't Trillian but it will definitely work when you need to play left hand bass parts.
I am not a big tech guy as far as using all the other stuff that this board contains. I basically wanted a good piano sound and good action. I actually think you could record a good solo piano album or trio album with this board. I run my FP7F through a Mackie DLM 12 and it sounds amazing.
Oh, I forgot to mention...the internal speakers aren't bad at all. I use them for practice and on the gig to reinforce the piano sound from the monitors.
I'm planning on keeping this piano for awhile. If you are a serious piano player then you should check this one out before you commit. There are a lot of options now. I used to own the Kawai MP9000 and loved it...but this one has it beat.
