Pipe organ
A more modern development was to have a "tubular pneumatic" action, in which the console could be away from the organ, but connected to it by tubes through which air could be pushed to open the valves. In the most modern pipe organs, the manual is connected to the organ pipes by electric wires. The power to open and shut the valves is controlled by electro-magnetic switches. The console does not have to be close to the organ. This makes it possible for the organist to sit in a position where he/she has good contact with the people in the church, or with other musicians.
