Hello dear fellow pianomen/women,

I finally decided to buy a digital piano. My choice is the Roland HP 305 and I should have it in a couple of weeks.

Since I'm also interested in technique regarding digital piano's, can someone tell me a little more about the V-Piano Supernatural sound? How is this different than sampling?

After nearly 25 years it's great to play the piano again.

Cheers

I don't think anyone really knows what it means in terms of the Supernatural engine in the new HP series. It probably owes more to the marketing men than the engineers. I think we all understand what it means on the V-Piano where no samples are used, it is entirely modelled. I think the message Roland wants out there is that the Supernatural thing endows the HP pianos with something of the behaviour of the V-Piano. For instance, they are claiming no looping and no detectable velocity layers. Quite how this is achieved when using sampled tones is not explained. Yamaha are claiming (and subjectively it would appear have achieved) the same thing with their SCM technology on the new CP series.

Cheers,

Steve

The Roland supernatural piano uses an incubus and a poltergeist to produce highly realistic sounds. smile

Well, that's probably more specific than Roland will ever be!

I note that you're being careful not to define "realistic"!

Roland's V-Piano's modeling technology is not the same thing as Roland's "Super Natural". The v-piano does not use samples at all. The HP307 is sample based. Roland has been releasing "Super Natural" sound for years now. They starting using the technology for drums then brass then electric pianos and now finally acoustic pianos. It is their term for sound that is run through some kid of parameterized filters. The samples are broken up into component sounds and added back in using some kind of weighted sum where the weights can be some function of time and user settings.

THis is not how v-piano works but the end result is supposed to be a bit alike.

The incubus and poltergeist explanation sounds more plausible.
Are you sure you are not describing Spectral Component Modeling?

And the winner is ChrisA for the clearest answer, thank you. Although it would have been nice to have an haunted instrument.

Roland does say that the HP307 has "V-Piano technology", despite the fact that it uses the "SuperNatural" sound engine. I would like to know what aspects of the V-Piano technology have been incorporated in the HP307. (re-reading the O.P, this isn't precisely what was asked, I guess)

Greg.

Well, I asked a superspecialist today. It's true, the HP307/305 uses some features of the V-Piano. It was a very technical story and I cannot remember the details. It had something to do with onboard samples that are enhanced the way V-piano does. I think it had to do with the 128 polyphone steps of each tone.

A haunted instrument isn't everything they are cracked up to be, mine is forever making me push the wrong keys.
