It came to be used in its broader sense with advances in knowledge about the fundamental nature of electrons and about the way in which the motion of these particles could be utilized. Today many scientific and technical disciplines deal with different aspects of electronics. Research in these fields has led to the development of such key devices as transistors, integrated circuits, lasers, and optical fibres. These in turn have made it possible to manufacture a wide array of electronic consumer, industrial, and military products. Indeed, it can be said that the world is in the midst of an electronic revolution at least as significant as the industrial revolution of the 19th century. Before computer memory-based samplers, musicians used tape replay keyboards, which store recordings on analog tape. Live Electronics From the late 1920s, the increased practicality of electronic instruments influenced composers such as Joseph Schillinger to adopt them. They were typically used within o...
