Abstract: A manual operating device (100) for providing a first and a second control signal in accordance with a user's operation, e.g. for controlling electronic musical instruments, stage/theatre equipment and/or audio/video studio equipment. The manual operating device (100) comprises a linear position sensor device (110), providing the first control signal (120), representing a linear position of a longitudinally slidable element (130), and a rotary position sensor device (140), having a body attached to the longitudinally slidable element (130) and providing the second control signal (150) representing the rotary position of a rotatable shaft (160) to be manually operated by the user. A MIDI controller device (210) may include at least one such manual operating device (100). Converting the positions parameters to advanced studio equipment MIDI control signals and/or to legacy MIDI synthesizer tone control.
