A device for sound processing comprising at least one external regulation element and an analogue effect, comprising - at least one digital regulation element, whereby digital regulation elements are digital potentiometers or digital switches, - one control button, - at least one memory location for storing positions of external regulation elements, and - a control circuit with a pre-downloaded software; - wherein the external regulation elements, which are analogue potentiometers or switches, are connected with the control circuit and a digital regulation element is assigned to each external regulation element; - wherein the digital regulation elements are connected (a) to the control circuit, from which they obtain data as to which position to take, and (b) to an analogue effect and the positions of the digital regulation elements directly determine a sound effect of the analogue effect; - wherein memory locations are connected with the control circuit or are a part of the control circuit; - wherein the control button is connected with the control circuit; - characterised by the control circuit being further adapted to control the device in compliance with the pre-downloaded software and in compliance with user's pushes of the control button, namely: (a) it selects whether a position of digital regulation elements is determined by external regulation elements or with pre-set positions of regulation elements stored in a selected memory location; (b) if there are several memory locations, the control circuit also selects which memory location is active; and (c) positions of external regulation elements are stored to the selected memory location; and - wherein the push of the control button shorter than n seconds represents selection of a memory location, namely a shift to a next memory location, and a push of the control button longer than n seconds represents storage of a combination of positions of external regulation elements to a selected memory location. - at least one digital regulation element, whereby digital regulation elements are digital potentiometers or digital switches, - one control button, - at least one memory location for storing positions of external regulation elements, and - a control circuit with a pre-downloaded software; - wherein the external regulation elements, which are analogue potentiometers or switches, are connected with the control circuit and a digital regulation element is assigned to each external regulation element; - wherein the digital regulation elements are connected (a) to the control circuit, from which they obtain data as to which position to take, and (b) to an analogue effect and the positions of the digital regulation elements directly determine a sound effect of the analogue effect; - wherein memory locations are connected with the control circuit or are a part of the control circuit; - wherein the control button is connected with the control circuit; - characterised by the control circuit being further adapted to control the device in compliance with the pre-downloaded software and in compliance with user's pushes of the control button, namely: (a) it selects whether a position of digital regulation elements is determined by external regulation elements or with pre-set positions of regulation elements stored in a selected memory location; (b) if there are several memory locations, the control circuit also selects which memory location is active; and (c) positions of external regulation elements are stored to the selected memory location; and - wherein the push of the control button shorter than n seconds represents selection of a memory location, namely a shift to a next memory location, and a push of the control button longer than n seconds represents storage of a combination of positions of external regulation elements to a selected memory location. <EOS>
