Abstract:
1. A system for controlling an assembly of pallets in an organ, wherein each pallet is actuated by an electromagnet actuator and corresponds to a key of the organ, the system comprising: a plurality of key dip measurement units for measuring each of said key dips as a function of time, converting analog key dip signals into digital signals, and for providing a plurality of digital key dip statuses using the digital signals; a communication unit for receiving said digital key dip statuses and relaying each of said digital key dip statuses via a serial link; a plurality of controllers for receiving the digital key dip statuses from the communication unit in a serial data stream, each controller being connected to one of said electromagnet actuators, each one of said plurality of controllers having a microprocessor addressable by the serial link, the microprocessor decoding the serial data stream to determine whether a corresponding key should be actuated, wherein said controllers control the electromagnet actuators upon receiving said digital key dip statuses to thereby provide for each pipe an opening proportional to the corresponding key dip status.
