Conventional HAUPTWERK keyboards have (static) permanent magnets under each key, which approach each other when the key is pressed and thus repel each other.

Diese Eigenschaft ist zugleich auch ihr größter Nachteil: Statische Magnete stoßen sich immer ab, ungeachtet der Bewegungsrichtung! Das bedeutet, dass Sie beim Loslassen der Taste ein unangenehmes “Hochschnellen” der Taste spüren und mit erhöhter Fingerspannung unterdrücken müssen.

On the other hand, if you take a closer look at a mechanical organ, you will notice the following:

A pressure peak occurs not only when the button is pressed down - the valve opens - but also when it is released! Shortly before the button returns to its rest position, the valve closes with a noticeable pull.

This clear separation between the outward and return path of the key is also of particular musical importance: as the organ, unlike the piano, does not allow for touch dynamics, the tone is shaped solely by controlling the speed at which the valve is opened and the air flows towards the pipe - very similar to the way a singer breathes.

The worst possible conditions for effective and, above all, relaxed practicing!

We are therefore using controllable electromagnets for electronic organ keyboards for the first time. An electromagnet consists of one copper coil per key, into which a magnetic pin embedded on the underside of the key is immersed.

Sensors detect the position of each key during playing. This position is then converted (depending on the selected settings) into the desired counterforce of the key and the coil is energized accordingly.

This means that almost any action can be reproduced true to the original - at the touch of a button!

KEYCHANGE KEYBOARDS are therefore the first choice when it comes to maximum realistic playing conditions - for the ambitious student as well as the demanding professional.
