Affordable piano controller based on a full grand action?

Affordable piano controller based on a full grand action? - 08/13/19 06:33 PM

I was idly browsing the Kawai site, looking at their GX7 grand.

Kawai GX7

If you click the picy of the piano it opens a viewer where you can move through the various picys in the slide show manually. Picys 2 and 3 are of the action.

How much does it cost Kawai I wonder to produce one of these? And, given that they make them already, how much would it cost to make a variation on it that was the basis of a controller keyboard?

I'm aware that Alpha Pianos do something like this, with Bosendorfer/Steinway/Yamaha actions I think, but, as I understand it, the price is very high. Does it really need to be? Is it so partly because they don't make the actions themselves?

If Kawai could produce something similar but at a sensible price point I bet that lots of VPC1 owners (like me) would try to get their hands on it the week it came out. It wouldn't matter that it was rather big and heavy because it wouldn't be aimed at the portable controller market.

Apologies if this has been done to death already.

Ian.

I’m currently working on this:


Some more info in my signature below. Too lazy to finish it since I already have a hybrid piano but sooner or later it will happen wink Just need to force myself to solder the rest of the PCB-s, half of them are ready.

Some unscrupulous non-Kawai dealers are already bashing Kawai pianos for their "plastic" actions. Now you want to give them the opportunity to say that the action from that expensive Shigeru is nothing more than a digital piano action in a wooden box. Nuh-uh!

Kawai and Yamaha provide that already:

http://www.kawai-global.com/product/nv10/ and https://ca.yamaha.com/en/products/musical_instruments/pianos/avantgrand/n1x/index.html

They are full grand piano actions with optical sensors in the hammer.

Thanks for the heads-up on that Luiz. The NV10 in particular is interesting and the action side of it certainly along the lines I was thinking. But you're paying for an awful lot of stuff - sound generation and amplification, not to mention shiny cabinet - that goes well beyond a controller keyboard. I just want something to run Pianoteq, and I build all my amplification stuff myself (to be the way I like it).

That's really impressive! I'm a bit of an electronics nut myself but if I started working on something like that I think the long-suffering wife would finally pack up and leave. All the best with it. I.

There are of course "off-the-shelf" products for MIDIfying an acoustic piano action, like e.g. PNOScan. (https://www.qrsmusic.com/PNOScan.asp)

You'll just have the trouble of finding a loose affordable grand piano action and screwing some screws. Unless you want to encase it in a case.

Robert Estrin at LivingPianos has some mysterious project going on: https://www.youtube.com/watch?v=3KlxlgUepOo

But I guess there isn't really anything new there. The technology already exists. It's just that some people want to do it better, hence CyberGene's DIY project.
