Grand Piano Keyboard Feel (vibration felt in fingers)

AvantGrand N3X has a "actuator"(*) that you can turn on or off just for that.
I added a 10" sub-woofer to my DIY cabinet mainly for that (and A0) - it works, probably not as good as the Yamaha but I feel the vibration on the keyboard and pedals.

I guess you can get a $30 actuator and stuck it to your keyboard no matter of it's size - a second one for the pedals?
I don't know what impact it will have on the amplifier and I'm guessing it would have to be dimmed down.

(*) not sure the correct name of these things - ah, Dayton Audio calls them "Sound Exciter"

Hmmm...I don't really feel anything in the pedals.  Though...cranking up the bass a little kind of does the vibrating feel.

My thought was a tiny vibrator under each key that piano vst makers could program somehow?

I've played a bit on a few AvantGrands and it is impressive how realistic and satisfying the tactile vibrations are. Like a real piano, it's particularly noticeable when playing the low bass.

I'm not sure how Yamaha does it, but it might not be particularly sophisticated...perhaps a bit like the vibration mechanism in cell phones, or the "rumble" in video game controllers? I imagine if a few, subtly tuned to mimic piano vibrations, were attached to the inside of the case itself, the vibrations might be enough to transmit up through the keys themselves--particularly while they're being held against the keybed.

I'd definitely like to see that added into higher-end controllers. Although most seem to still need a lot of work on their action first!

That makes sense, and I haven't played the others, but the AvantGrand did have some sort of vibration mechanism as you could turn the strength of the effect up/down. Now maybe it still did this through speakers...with infrasound?? But I imagine a simple mechanical spinning device would be more cost effective?

Yamaha doesn't seem to give much information on how their "TRS" system actually works: https://www.manualslib.com/manual/13143...=25#manual

It's been several years since I've played one, and I didn't play any extensively, but I would say the effect was far better than nothing. Could it have been improved? No doubt. But only having experience with real pianos and standard keyboards, it was a very nice improvement on the latter. It also did react to volume and frequency, being much more pronounced in the bass, less so as you moved up, and stronger at greater dynamics/bigger chords. Was the speed of the vibration faster depending on the pitch being played? Possibly not, but I imagine that wouldn't be too difficult to implement.

I wonder how Roland would implement such extra keyboard touch vibration. Roland have somo nice key mechanism, but none made from wood, despite some plastic keys have wood tiny strips in the sides of the plastic.

Sure, pianoteq offers the best possibilities for tranducer activation on soundboard and keybed.

Pianoteq technology can split sound in channels for each piano component, while sampled pianos can't that easy. Modartt could create a channel for soundboard, and a channel for piano cabinet and even one for the keybed vibrations. They can also create a channel for some speakers, required for some metal tones of the harp and deep trebble, as well one for the acoustic sound which the strings produces direct to the air.

I would even go beyond, if I was a piano manufacturer. I would invite Modartt and together tfy to design some sort of metal harp to be used with transducer, taking advantage of Modartt ability to create a channel just for it.
