String Resonance

Does the Kronos have string resonance like the nord stage 2? I know the kronos has damper resonance.

Yes, from what I have read and seen about the Kronos it does have sympathetic string resonance.

From Korg.Com Kronos specs ...

Premium Piano:

PCM:

EXs6 - SGX-1 German D Piano; EXs7 - SGX-1 Japanese C Piano

Piano Type:

32

Oscillator Control:

Damper Resonance, Damper Noise, Mechanical Noise, Note Release

Damper Resonance = Sympathetic String Resonance

Thoraldus, Thanks 4 the reply!

So this works even without the use of the damper pedal?

I doubt the Kronos supports string resonance (e.g. gently hold down a D triad, then loudly play a low D and the triad will quietly sound). I have not heard anything about it, nor was it mentioned in the SGX-1 video. I find it to be a subtle effect. Roland has had it on their RD series for sometime and I'll bet 95% of the owners are unaware of it. Roland never made a big deal about it where as Nord did.

that would be the VERY sympathetic string resonance

Yeah burningbusch.... I was searching for that in the sgx-1 vid. I'm sure it ads something to the playing but I think all the effects that the kronos offers will outweigh the Stage 2's piano samples.

On another note.... Any Upright's in the Kronos?

I don't know. In the EXs4 Vintage Keyboard library there are two pianos listed: Stw-1 A.Piano and Stw-2 A.Piano. Maybe they are variations of the same piano. I don't know why they would be listed in the Vintage Keyboard library along with EPs and clavs. Maybe they're uprights.

Damper resonance and sympathetic string resonance are two different things... As burningbusch says, I didn't hear true sympathetic resonance in any of the demos. And the ultimate test for this is as busch explained - silently hold a chord, then play the root of that chord several octaves above staccato - the chord should ring along with the staccato note.

Even the triton series has damper resonance I'd have to check how it performs but I'd thought it 'undamped' the currently active strings..

It is still a very subtle effect and I've hardly seen the point.

From the KRONOS Parameter Guide ...

The SGX‐1 Premium Piano EXi is designed to provide an optimal acoustic piano experience, combining world‐class sounds, subtle performance nuances, and a dedicated, easy‐to‐use interface. Features include:
• Full chromatic sampling, with every note sampled in stereo at up to 8 velocity levels, for natural and smooth response
• True damper resonance, also chromatically sampled, with multiple velocity layers
• No loops: sounds decay naturally
• High polyphony—up to 100 dual‐stereo voices, the equivalent of 400 mono voices
• Realistic performance nuances, including mechanical noise controlled by release velocity, damper pedal noise controlled by pedal velocity, and note release

I guess we need someone from KORG to define what "true damper resonance" means.

Once again: damper resonance is NOT the same as string resonance.

These kinds of effects are best heard with solo piano that is not too busy and has sweetly clangorous bass rumblings and held chords that take advantage of these resonating inharmonisations.

Moody classical and thoughtful new age pieces can naturally reach for this, and for sweeping improvisers it's one more color on the plucked piano soundboard pallet.

And with the Overb, and a superb sound system, and an open, expansive, listening space, it's pure loveliness...

Would you like to share your knowledge with us and tell us why the 'True' Damper Resonance on the KORG Kronos is not "string resonance"?

Kronos has resonance only if you press damper pedal, and it is resonance of all strings at once.
Real piano also has resonance when damper pedal is not pressed, but only those strings resonate which are not damped at a particular moment. I.e. if you hold C3 key, then you release damper from strings on C3 note, and then those strings will resonate. For example, if you then play and quickly release (i.e. play it stacatto) C4 note, then C4 tone will still continue to sound even after you release C4 key, because it will be picked up by resonant strings on C3 note that you are holding.

When you press any key, it is un-damped. So why should Korg's 'damper resonance' not include notes which are held down other than with the damper pedal?

It all depends on the mechanics of the actual programming, which I think either you'll have to get an answer from Korg, or you'll have to figure it out for yourself by turning the noise element up in the SGX-1 engine.
