The ©Feurich High Speed KAMM Action is the solution to the gravity conundrum of the vertical construction – it lets you play an upright piano like a grand.
Together with Udo Kamm, we have developed a completely new concept for the Feurich 123 – Vienna. Produced by Renner, and implemented in a newly-patented system, this piano action enables an extremely fast repetition normally only found on the best grand pianos. For a perfectly even and balanced touch between black and white keys, there is a difference in the design of the wippens which compensates for the differing length, and therefore leverage, of the white and black keys.
Thanks to the High Speed Kamm Action, the Feurich 123- Vienna plays lighter and more precisely than any other upright piano on the market. The best thing: This ground-breaking new patent is not restricted to Feurich owners, but it can be installed in most pianos made by other brands.
