Hello

I recently bought the Synthogy Ivory II American Concert D piano, overall very pleased with it (running standalone), but the low G (and to a lesser extent the B and D above) seem to my ears to have an unpleasant 'twangy' overtone that's really distracting - just wondering if it's my ears at fault so would appreciate if folks could take a listen to the sample clip I recorded (direct to Quicktime).

I've been playing it through my N1X both over speakers/headphones and however I listen to it, even cutting the N1X out completely as per the clip, there's this horrible metallic twang on this bottom G. I've not heard any mention of it anywhere else so maybe it's a defect in my ears!

In the clip (google drive link) I play low F/A/C followed by G/B/D - it's the G that's the most obvious in its twanginess to me. There's also a short Kapustin excerpt where that bottom G sounds 3 times - jumps out a mile to me.

If someone can take a listen I'd appreciate their thoughts.

Thanks all

Yep - definitely hearing a metallic 'twang' on that note. Unfortunately the Ivory engine is locked for "under the hood" sample tweaking, unlike many Kontakt based pianos where you can simply remove the sample in the mapping editor and stretch a neighbouring sample over the offending note.

Hello,

@jwpiano80, Welcome to this forum.

I listened to your clip multiple times, using quality HiFi equipment.

Usually I am very sensitive to problems such as you describe. Yet, in your clip, nothing strikes me as extremely off.

I do hear timbre differences, where the Cs in the F-A-C sequences sound the most different from the rest--being duller/less metallic sounding than the other five notes. This could be in the sampling/scripting or in your fingering.

Given that in this clip the G you are worrying about follows that C, *in contrast* it is brighter than that C. But as said, the C sounds more different than the rest to me--in the duller direction.

The little jazzy snippet is too busy to make out anything useful.

Hope this helps!

Cheers and happy playing,

HZ

Hello thanks for the welcome and replies. It's disappointing that there's no facility to 'correct' anything in this instrument but I'm somewhat relieved that it's not my ears

It's probably a quirk in the Steinway piano that came out during the sampling session, which is usually automated robotic recording of single key samples in 20+ velocity layers. The grand piano would probably not sound that way when played by a human with normal music. A human pianist would also compensate for slight regulation differences, while you are just triggering samples by MIDI.

That's why when creating a digital piano, flawed samples like these need to be thrown away, because they obviously ruin the entire mix. This is what Yamaha did for the CFX (recorded in an anechoic chamber) stored in the N1X and Ivory did not.

Conclusion: You purchased a flawed product.

VSL definitely have a piano robot that plays the keys, but Synthogy don't - in the manual there are credited pianists Janice Weber and Joe Ierardi for the various recording sessions.

Also in this video
Joe demonstrates the process, I would have assumed this would be automated but seemingly not with this company.

Either way, the flawed product point stands. I suppose I can still use it for pieces that don't use bottom G crazy

I too was disappointed with this piano. However, if you try to play it exclusively in una corda mode, you may find it interesting and even inspiring. Besides, any piano has imperfections, and sometimes the positive features of it may screen the imperfections.

To me hearing that(which sound awful) I could describe it as a large diaphragm mic off-axis to the sound source. Large diaphragm mics off-axis response gets extremely uneven and they are known to exaggerate the harmonics of a source when off-axis.

Off-axis evenness is a characteristic small diaphragm mics have that large diaphragm mics don’t.
