Claims (1)

[Claims for Utility Model Registration] 1. A device including an operator for selecting and setting various data for controlling musical tones, presetting various data for controlling musical tones, and selecting the preset data. A preset control device for an electronic musical instrument, comprising: a preset device for preset data; and a partial prohibition control means for selectively controlling whether or not to prohibit the use of a part of preset data when the preset data is selected by the preset device. 2. The device including the operator includes a plurality of operators, a storage device provided corresponding to each operator and into which the selected setting state is written each time an operation is performed, and a memory device provided corresponding to each operator and storing the selected setting state. a display device that visually displays a selected setting state stored in a storage device; the preset device includes a preset data storage device that stores the preset data in advance; and a set of presets from the preset data storage device. means for selecting and reading data and writing it into the storage device, and the partial prohibition control means includes a prohibition switch and a preset read out from the preset data storage means in response to the operation of the prohibition switch. Scope of Utility Model Registration Claim 1, which includes a control circuit that prohibits writing of a predetermined portion of data into the storage device, and controls musical tones based on the data stored in the storage device. A preset control device for the electronic musical instrument described above.
