= 72 = The sequencer is a control voltage source which may be used to regulate voltage-controlled oscillators, filters, amplifiers, and the like. It consists of a number of points, or stages, at which voltages that have been manually preset are present. When they are activated, these stages run in the order in which they were set. The speed of the sequence is also manually controlled. After it makes one complete cycle, it can be programmed to repeat continuously. In order to produce a similar effect in a classical electronic studio, a tape loop containing individual frequencies would have had to have been, prepared, a very time-consuming task.
