Pardon me? I'm not stopping you geeks from comparing test results.

If you can question my motives for trusting the word of respected professional people, it shouldn't bother you if I question the integrity of a test that can have errors, bias, or both.

Just skip my posts if you don't like them. Start another thread if you feel like it.

Last time I looked we all have a say in any topic.

Regards,

Colleen

Yes I agree, those that have played the CP1 seem universally impressed. I'd love to try one but would probably have to travel a couple of hours in the car to find one.

Like I said, let us know what you think when you try the one the shop is ordering...maybe put something on the other thread specifically about the new Yamaha stage pianos.

The next big deal is going to be a proper comparison between the CP1 and 5...on the face of it the 5 appears to offer better value.

Cheers,

Steve

Hi Steve,

I will post my impression as soon as possible.

I'm more interested in the CP-1 for it's acoustic piano, and equally as much, the Rhodes emulations.

I play an old Fender Rhodes at church, and it's action is very uneven and the whole instrument itself needs a lot of work, new hammer tips, and perhaps an overhaul of the action.

I don't need organ sounds, as I have a Hammond A-100, so the wooden ungraded action of the CP-1 will be perfect for my style, plus I can adjust the sounds to my liking.

The Rhodes I'm presently playing is too bell-like in the top octaves, and is using the old style tone-bars, so being able to adjust with the CP-1 will be nice; also the DX Electric piano will be very nice for slow pieces.

I think they will probably bring in CP-5's when available.

If the CP-1 doesn't quite meet my conditions, I'm also going to look at the RD-series with the added Supernatural piano card.

I'll be looking forward to your impressions of the CP-1 as well.

Best regards,

Colleen

Does anyone know where a CP1 can be played in the Los Angeles area? I keep thinking there's got to be one available to try around here, but I haven't been able to find one yet.

Thanks very much for the file kawaian!

This DP has nice things going for it. I couldn't see much in the way of stretching, and couldn't hear it at all as it was only on some of the upper notes.

Layer blending is also very well done.

Looping and sample length are about par for the course, and note decay is a bit fast, though there is some quantization noise in the sample that keeps me from hearing everything going on near the noise floor (most likely introduced during the DPBSD recording process, and probably not something the DP itself is doing).

--------------
- Kawai CA63 -
--------------
FILE & SETUP:
- dp_bsd_v1.3_kawai_ca63.mp3
PROS:
- Large dynamic range (~51dB, vel=1:127).
- Looping is fairly well done.
- No audible sample stretching.
- Stretch distances: 1(x72),2,4,2,1,1,2,2,1,1 = 81 groups.
- This is a very smoothly blended multi-velocity layer sample set.
- There are three semi-visible velocity switches @ vel=46,78,124 (4 layer?).
- Responds to partial pedaling.
CONS:
- Looped, though not too badly done.
- Samples lengths are (C2:C9) 3,3.3,2,1.6,1.7,1.6,1.3,0.6 seconds.
- Note decay rather short (~1/2 Pianoteq).
- One velocity layer switch is fairly audible (timbre change) @ vel=124.
- No obvious pedal up/down or key up samples.
- No obvious sympathetic resonance.
OTHER:
- MP3 levels very good: peak @ -3dB, noise floor @ -78dB.
- Some "mosquito noise" at noise floor - quantization noise?
- Date reviewed: 2010-02-16

That's interesting Dewster as I think I remember that Kawai claims to use 88 note sampling on the CA-63 and CA-93. How clear is the stretching from your analysis?

Best wishes,

Steve

I haven't seen such blatant tag teaming among friends and meaningless statements like those shown on this thread since the old PSS threads on the acoustic forum!

Great stuff. Truly entertaining.

" I don't trust data or my own fingers and ears; I blindly copy the behavior of those I see as authorities because it is easier and safer! "

" I ordered one and so did my student." But (later:) "we are not committed to buy as the store was getting two anyway!"

" Soul can't be analyzed by a computer with its squiggly lines. If the facts don't look good, trash the facts! "

I wasn't aware of their claim, but here is the spectral view of what I'm calling the 2,4,2 stretch groups on the CA-63:


The 2 group on the right might or might not be a real one, but the 2 group on the left and 4 group in the middle look pretty definite. I will say in my defense that it gets very difficult to see or hear these things on the upper end of the keyboard. I could be entirely wrong, but that's what it looks like to me. It isn't audible (to me).

I'd say the CP-5 would be the best deal for stage use if you only want to bring one keyboard....I want strings, organ, brass and clavinet sounds.

Won't see a CP-5 for a bit yet.

Snazzy

Well the spectral view certainly shows something quite definite, I agree. On the other hand, if you can't hear it chances are no one else would!

Cheers,

Steve

End of March did I read? It does appear to be the sweet spot in the range.

Steve

Gee, Joe...you and Colleen think the same.

How sweet.

You getting a CP-1 too?

Good luck...they're scarce.

Snazzy

They are a mass-produced consumer product with less than revolutionary technology made by a huge Japanese conglomerate out of perhaps a hundred dollars of plastic and silicon.

The only scarcity that matters is the scarcity of people willing and able to spend thousands upon thousands of dollars for a digital stage piano that is most noteworthy to date for its ho hum trade show demos, team cheers on forums, slick marketing brochures and a massive dim-able product logo on the back. Yee hah!

It's the new un-graded wood keyboard that I'm very interested in, otherwise the CP-50 might be pretty good for gigging and/or home play.

The CP-5 and CP-50 also have the same display but the CP-5 has balanced outs like the CP-1.

End of March appears to be right.

Snazzy

dewster, yes the CA93/CA63 utilise 88-key sampling (as do all other KAWAI DPs released since the ES6).

I too would be interested to see your spectral analysis of the top notes from a purely modelled source (V-Piano, Pianoteq). Perhaps note stretching would still be visible (as in your CA63 analysis), despite the fact that this is obviously not the case.

Cheers,
James

I recorded the P-80 again, this time with reverb off:

Sounds right up your alley. Joe.

You could also get the logo put on your big hat.

Snazzy

I love this place.

Like you, I've been disclaimering my ass off throughout this entire thread. I was seriously considering writing a script or something that would automatically insert IMO at the end of every one of my sentences. But implementing Operation Ignore changed all that.
