New Yamaha retrofit silent unit and grade up unit.

Queue99

Hi there, I have an 1994 M100 (seems to be pretty much like an U1 produced for the European market with an optical Silent System). Have moved this to the US now, but the Silent System has been acting up (some keys not playing others very loud), and several US technician (Yamaha experts) told me a few years ago <2018) that this is an electric board issue. Now with the new VSH3 option, I am wondering if I can upgrade my system with VSH3 rather than trying to 'repair' the optical one (as I have no idea how - apparently the electrical board is no longer produced).
Do you know if the VSH3 would work with the M100 (M100 is not on the official list of compatible devices - maybe because it is an European and not a Japanese Model)
If you think that VSH3 is compatible, I would be very interested to purchase one.
Thanks in advance for your help

Paulo164 Thank you for this review, very helpful! Just wondering if you've compared the SC2 to SC3? I ask because I'm thinking about purchasing a gently-used C3X TA2 grand piano, and just wondering how the silent sensor mechanisms SC3 - magnetic sensors vs SC2 - optical and gray-scale shutter, compare? Also, does anyone know if TA2 can be upgraded to TA3? I figure they share same controller box (SHx and TAx)…

Thanks,

Scott

The M100 is the same as the Japanese version of the U100SX, so the VSC3 can be installed.

I believe the M100 is a first generation silent, so the key sensor board is corroded.

I've been experiencing this symptom a lot lately.（U5AS、U30AS、U300S、U100SX,U300SX,etc)

Parts were no longer in supply.

I guess vintage synthesizer repairman may be able to fix it.

I guess RSH3 is better than VSC3, the reason is that the old silent mechanism is also replaced and the touch when silent is better.

Hi,

On the paper, the SC3 has this over the SC2:

• "Articulation Sensor system" to detect force/acceleration in addition to velocity for staccato/legato playing (CC19)
• Binaural samples for Bösendorfer Imperial
• MIDI bluetooth
• Added arranger to be accompanied by bassist and drummer
• -30% of current consumption (12W -> 8W)

Also, looking at the MIDI specs sheet, it seems that:

• the SC2 doesn't handle CC#88 (so no high-res velocity)
• does handle Poly-Aftertouch (for smooth release), like the SC3

On the field, I can't tell you which one performs the best but I would go with the SC3 anyway, should it be for maintenance easiness alone.

Paulo164 Thank you very helpful! Just wish the Yamaha's were less expensive in the US. The dealer markup is unbelievable. 🙁

Thanks a lot for the details! Super helpful. I inquired with Yamaha in Germany and was told the MP100 Silent should be compatible with the VSH3-10. I am a bit confused that you say RSH3 is better than VSC3? Do you mean RSC3 being better than VSH3? Is the VSH3/VSC3 not replacing the silent mechanism?

I assumed the VSH3 would be the same as the RSC3, but without the silent rail?

Can you elaborate on the 'key sensor board' being corroded? How could a synth repairman fix it? I might try to find someone like this here in San Francisco, but am wondering if the sound / reliability in the new VSH3 is not so much better than the old system, that the upgrade is worth anyway?

skywalker

It was a typo. It’s RSC3 or VSH3 only.

And yes, RSC3 = VSH3 + hammer stop bar - some features on the control unit.

Otherwise, same quality.

skywalker

Yes, the upgrade is worth anyway.

As you can see from the photos, the board and components are corroded due to liquid leakage from the capacitor on the sensor board. The microscopic patterns and through holes are broken and cannot be repaired by simply replacing the components.

Vintage synth craftsmen and board restorers are good at this repair.

The first generation silent stoppers were board-like and difficult to adjust section by section.

It would be preferable to replace them with new silent mechanisms in the RSC3.

SH3 has a better SPEC than SC3.

Thanks so much for the details and clarifications, will have a detailed look at my unit this weekend, but guess it is anyway better to upgrade to the new system.

Just need to find a way to get one shipped to the US. Will see a Yamaha store on Saturday - maybe they can find a source… otherwise they seem to be available in Germany.

Hi there,

In the Netherlands Yamaha sells the VSC3 but not the RSH3. Can you explain the difference in components in the 2 sets like:

1. Mute rail
2. Sensor rail
3. Control unit
4. Other things?

Thanks!

Dirk from what I understand there are slight differences in the control unit (see listing here) with regards to the number of included instruments/sounds. The RSC3 seems to be to retrofit pianos without a previous silent system installed, the VSH3 is for existing silent pianos thus does not include the mute rail. The sensor system seems to both electromagnetic (the link above says optical but then electromagnetic below). I bought the VSH3 to retrofit an old M100 model with optical silent system and definitely is the latest elector magnetic rail.

Search for ‘Yamaha SC3 vs SH3’ and you will find some Yamaha shop links with more information. You can also call a Yamaha shop for more info. I live in the US but got my unit from Piano Ebert in Konstanz Germany.

Vincent Muck was super helpful and savy.

Hope that helps!

Mr Skywalker is correct. Install the RSC3 on Yamaha pianos that do not already have silent unit.

I can send you an RSC3 if you would like me to.

Hello, I am new to the forum, found it while searching for piano silent systems.

I tried to mention Mr. Queue99 but it seems I don’t have the permission for @ / mentioning a user.

OK I just found out about the limitations for newbies. 😀

Sorry to spam here, but I need to post 5 messages to get rid of newbie status.

painano the limitation stays for the first 24 hours even after 5 posts but I removed it manually for you.

CyberGene thank you!☺️
