grand action in an upright

[Quentin Codevelle]

Hi List,

This year at the Frankfurt Musikmesse, there was a presentation of a new type of action for an upright.
As far as I know, it consists in adapting a grand piano whippen in an upright mecanism, that way you have better repetition.

Has anyone ever seen or heard from this system?
I'm looking for information about this, but I can't find any website..

Thanks,

Quentin
