I was wondering what piano are the Casio Privia sampled from. The Yamaha digital pianos are probably sampled from their CFIII grand. Since Casio does not make acoustic pianos, would the piano sound be sampled from a piano or just produced from the computer? Thanks.

I've always 'felt' they sounded like Steinways. I've owned PX310, PX575, and PX320.

It's definitely sampled from *something*. That's how nearly all digitals produce their sounds. A Steinway would be a reasonable guess, but it's hard to tell. Roland also supposedly samples from Steinway, and the Casio and Roland don't sound particularly similar. I would just say that it's sampled from some unknown high-quality acoustic and leave it at that.

I was wondering about the same thing too. Another thing, this could be due to my relative inexperience with pianos in general, but I find the high treble notes slightly jarring to the ear. I like a bright piano sound (I mostly use the modern piano setting) so this might be a reason too. Unfortunately, the acoustic pianos in the music store I frequent are mostly rubbish where the highest note sounds more like a *thump* than a note, so I can't make an accurate comparison. Or are pianos really that way?

Never thought about this before, but now I also wonder what Casio takes it's samples from. Ugh, this is going to bug me until answered.

No one ever found an answer to this? I thought Mike from Casio would've answered. *shrug*

From the Privia web site, it's an older article, but it answers the question (I think)...

"The PX-400R�s 256 superb digital tones range from pianos and strings to wind instrument and synth sounds. Casio�s innovative new HL (Highly-compressed Large-waveform) Sound Source audio processing chip delivers exceptional sound quality by employing a proprietary dual-element sound source that accurately reproduces the sound response of acoustic instruments. The development process started by taking stereo samples of a world-class concert grand piano and storing the resulting sample waveforms in PRIVIA's memory. Separate waveforms are used for strong keyboard pressure and light keyboard pressure, providing a full range of dynamic expression, from lilting pianissimos to thundering fortissimos, providing the player with incredible realism in tone. Sound is further enhanced by a pair of semi-custom speakers to ensure optimum sound quality throughout the full 88 key range."

I've been playing a Casio Privia PX310 daily for almost three years. Whatever they sampled it from, there's no p or pp tone; just a lower volume of the mp/mf tone. That's what eventually led me to VSTI's, of which I prefer Ivory. My px310's built-in piano sound has, as far as I can hear, three sounds or tones: mp/mf, f, & ff (when you slam the keys).

I personally think they sample's from a Steinway. I've read more than once someone commenting on how Casio's sound a lot like Rolands, on headphones anyway. I've done some searching but can't find a definite answer to this question. I'm almost tempted to email or pm Mike, just to sate my curiosity now. lol
