Leadless Keyboard


This allows us to completely dispense with toxic lead in the piano. Instead of lead we use a high-density plastic for the balance weights of the keys. Weighing is done by removing weight from this plastic.


Advantages are apparent:

  • no more toxic lead in the piano

  • no blooming of lead

  • no hanging or bursting keys

  • no weakening of the keys by drilling



Guarantees permanent additional sound volume and projection due to improved elasticity and tension of the soundboard.

SMR (Super-Magnet-Repetition)

SMR garantiert eine bisher unübertroffene Repetitionsgeschwindigkeit im Piano. 

Durch zwei sich abstoßende Magnete, die in einer herkömmlichen Mechanik eingebaut sind, wird das Einfallen der Stoßzunge unter die Hammernuss deutlich verbessert. Zudem ist SMR völlig wartungs- und abnutzungsfrei.

Frenator System


Avoids unintended closing of the fallboard and thus improves comfort and safety.

Improves the resonance characteristics of the soundboard and leads to the perfection of the typical, transparent Seiler sound.
