Sympathetic Resonance is another term for String Resonance.

You can listen to this: HERE.

So in the CLP-2xx series only the 270 and 280 have this feature and in the new CLP-3xx series only the 380.
The CP-300 has it too.

For the Roland HP-2xx: 203, 204 and 207 have String Resonance. So has the FP-7.

For Kawai CA series: CA-51, 71, 91 all have String Resonance.

I read here that the Kawai CA-51, Roland HP-203, Yamaha CLP-280 all failed the test, which follows the quote of the Yamaha technicians.

But in this case Eronaile's CLP-330 should have passed since it has no String resonance?

Beside this, it's very strange that all the high end digitals with String resonance fail this "reality test"!
I mean, just like Jscomposer suggests, i think it can't be that difficult to make the software let just cut the String Resonance samples/sounds so that the note you pressed again still sustains, but minus the String Resonance samples/sounds of the other notes (those you do not press anymore) because they are now dampened.

The extra Stereo Sustain Samples (a feature of the Yamaha CLP-340,370,380 and 240,270,280 when you press the Sustain pedal, also called Damper pedal) are nicely cut off when you release the right pedal again, so it must be possible to let the software cut off the extra String Resonance samples at the moment they are no longer needed.

( 'Stereo Sustain Samples' is a Yamaha term, Roland calls it 'Damper Samples' in it's HP-201 to 207 series. )


Any clever technicians there to explain what's the problem to get this right?

Just tested it on my RP700. It did not pass this test, though it does have sympathetic resonance, and a sostenuto.

When I get back to the shop on Monday, I'll check out the pRP 800 we have. I wonder if it makes a difference if one has the optional 3-pedals, vs the standard footswitch sustain pedal that they come standard with.

I have noticed the actions on the pRP 700 and 800's feel much better than the 'console' RP700. The action on the console RP800 though is good though.

Fascinating thread. I never noticed this flaw on my HP-207, but there's no excuse for Roland not getting it right. We'll see if they do in their next model line..

My CLP-380 passed the test.

Casio AP-45 does not have string resonance, using the test described, but does pass the sostenuto test. Sounds like the theory is a good one.

I went to the store and checked a few. The CLP 240 works, CLP380 works. Actually I tried 4 or 5 of the Clarinovas and they all worked. I just can't remember the model number for them.

My "old" CLP-115 passed the sostenuto test...

The CLP-380 has String Resonance AND passed the 'sostenuto test' three times in this thread!

It looks like Yamaha found a way to get it right in the CLP-380 to.

So there's no reason why it schouldn't work with the CLP-320, 330, 340 and 370.

Eronaile can you do the test again, because your CLP-330 should have passed following the theory, since it has no String Resonance?

Well, I'm 100 % certain that it doesn't pass, if I had a cam I could record it

Just to be certain: I press the pedal, strike a key, let the key go, strike it again real slow so the note doesn't sound a second time, then depress the pedal while holding the key. Result, the sound stops when I let go of the pedal, while the key is still pressed.

Just tried it on my ancient Yamaha, the long discontinued P500.

Passed with no problem.

i actually tried the test on my PF500, which does have string resonance, but it's not always working unless i hit the key a little harder (with slight sound) when sustain pedal is still down. actually, the sostenuto pedal on mine works as on a grand anyway.

Hey, all! I mainly play my S&S B, but I have a CLP230 as well, and it passes the sostenuto test.

So here's a stupid question:

If one were to get a Kawai CA51 that does not do this properly, but hook up the piano to Garritan or Ivory or Pianoteq, etc. would you then have it through the software or is it a signalling & reproduction issue?

Casio px 120 also fails.

theJourney,

at least the combination Roland HP-203 + Galaxy II Steinway does not work.

If would be a function of the software.

My Casio PX 320 failed the test

that's decided it, its got to go

Just got off the phone with Rich from Shawn's Piano, and the pRP800 failed this test.

O.K., but after all of this, how practical is this in a real solo performance situation? Do we have the time to do the "second depression" thing in a real situation?

I use it in Rachmaninoff's Prelude in B minor, in Grieg's Concerto in A minor depending on what mood I'm in, and I use it in some of my own music. The main reason I developed it was because my DP doesn't support sostenuto. But you're right, so far I've only used it in slower passages.

Come to think of it though, this technique could be used (and perhaps with greater ease than sostenuto) in a situation where you play a fast run and then want to sustain only certain notes from that run in the next phrase.
