New Yamaha retrofit silent unit and grade up unit.

Queue99

Yamaha will release the new RSC3 series of silent retrofit units and the VSH3 series to upgrade your existing silent pianos on May 18 in Japan.

When the RSC3 and VSH3 upgrade kit are released, you can buy an old piano or old silent piano at a discount and upgrade it for a good price.I guess up grade unit for grand are especially affordable.

Interesting. Not clear to me (with Google Translate) what advantage this upgrade has compared to the old ones.

CyberGene an equivalent upgrade can be performed some day on the AvantGrand pianos.

This upgrade (like all silent systems on acoustic that I know of) senses the keys. The AG senses the hammers, so I wonder what you'd expect. In fact, I wonder why Yamaha does not include (at least in its premium silent systems for grands) shank sensors as you have done for Cybrid. I suspect it's because the geometric tolerance make it extremely hard to service (whereas in the AG the absence of the strings ease this concern, but still....)

Nice. Wondering if an equivalent upgrade can be performed some day on the AvantGrand pianos.

I didn’t read the details. I thought it was about the new type of radio sensors under the keys which are supposedly better than the current optical gradient sensors. But honestly I don’t even know any details and why those are better.

I think you are correct here. That website (Google Translate) say

Through wireless communication between paired sensors, the movements of key presses and key releases on the keyboard are always accurately grasped. By installing sensors under all 88 keys so that they do not touch the keyboard, natural performance is possible without impairing the original touch of the piano.

But still I think that won't provide a huge difference (if any difference at all) on an N1? I've not seen anybody elaborating more on how/why these "wireless" (radio? perhaps something similar to RFID?) should be better compared to the LEDs. Sure, the latter eventually fade in intensity, but that could be calibrated automatically at each start-up, and they can be replaced easily when they totally die, but other than that? I doubt that RF can provide better spatial or temporal resolution, but I am just speculating without knowing anything here. Maybe @JayKominek or someone else knows better?

For key sensor, it says "非接触連続検出電磁誘導センサー" which Google translates to "Non-contact continuous detection electromagnetic induction sensor".

Probably something simpler than RFID. Based on the picture and the requirements, you put some sort of little inductive loop on the under side of the key stick, and then design the most inductive thing you can out of PCB traces, that hopefully directs the magnetic field straight up(?). Then constantly measure the inductance of whatever you built on the PCB. It'll change with distance.

You get a lot more design options when you're Yamaha and can design/fab ASICs. 😔

VST-Player Does this upgrade have 3 sensors or only 2? The existing retrofit silent systems in uprights sometimes shoot loud notes when you repeat a key because the hammer is still in the air and there is no weight on the key when you repeat it which results in a high velocity.

This new sensor (and the previous one) should be continuous-detecting, so somewhat equivalent to infinite number of sensors. The problem you describe (which the NU1 has also) is inherent in how the upright actions work and can be eliminated completely only with hammer (or shank) sensors -- everything else is mitigation factor which will never completely eliminate it.

Okay, so just magnetic field like @aleath is doing or perhaps @xooorx ? I thought it was more sophisticated 😉

Google translate is hit-or-miss. So I checked with some engineering and general dictionaries and confirm the same results...in this case.
