The present invention concerns a method, an apparatus and a computer-readable storage means for adjusting at least one parameter, which can be used for enhancing the user experience of adjusting parameters, especially of adjusting parameters in common audio software through a system of assignable rotary encoders with capacitive-sensing knob caps and a parameter type aware software. The invention especially enables a quick adjustment of several parameters by use of rotary encoders.For this purpose, a method is proposed, where at least two touch sensitive input elements are provided for adjusting the at least two parameters, at least one of the at least two touch sensitive input elements is selected by contacting it with at least a first part of the human body, and the at least one parameter, which is assigned to the contacted touch sensitive input elements, is adjusted by operating, with at least a second part of the human body, at least one input element different from the contacted touch sensitive input elements.
