Abstract
The invention provides an actuator for actuating a pallet of a pipe organ under the command of a key of an organ. The actuator comprises a movable member, adapted to be connected to the pallet of the organ pipe and a magnetic plunger, mounted on the movable member. It also comprises an electromagnet having a gap within which the magnetic plunger can be inserted and moved, wherein the electromagnet when energized moves the member to thereby actuate the pallet. A controller unit controls a current in the electromagnet to provide a controlled actuation of the pallet that is proportional to a key dip of the key. It also provides for a system based on a digital serial link for controlling an assembly of organ pallets that are actuated by electromagnets.
