ABSTRACT:
A device for generating a variable and adjustable control signal is provided. The device is of the type in which the control signal is generated in response to the manipulation of the device by an operator and is applied to suitable controlled amplifiers such as voltage controlled amplifiers or filters. The device comprises variable voltage generating member and a holding circuit coupled thereto. The voltage generating member is capable of delivering a voltage corresponding to the location where the operator touches or presses and when the voltage generating member is not touched the voltage generating member is inhibited from delivering a voltage. The holding circuit delivers a first signal corresponding to the voltage delivered under the manipulation of the voltage generating member, and holds a voltage corresponding to the previously manipulated location and delivers a second signal corresponding to the held voltage during the time the voltage generating member is not manipulated. Thus, either one of the first and second signals is used as a control signal variably adjusted by manipulation of the voltage generating member.
