1984, For the control organ symphonic

摘要

The organ control is provided from two computer networks. The first network is comprised of a number of processors with a parallel processing architecture, with digital inputs and outputs to respond to the keys on a keyboard by sending a high speed (over 20 Mbit/s) signal through a MIDI interface to the solenoid actuators for the pipe valves. A second network of conventional personal computers acts as an interface to each console of the organ(s) to program operation of the solenoids in response to specific signals received from the controlling network.
