ABSTRACT:
An arrangement for presetting musical tone effects in an electronic musical instrument in which a first system is provided with a plurality of tablet-shaped switches which are connected through respective memory elements in a memory circuit to respective control electrodes of a plurality of gates for selection of musical tone effects. A second system is also provided with tablet-shaped switches which are connected to control electrodes of gates for selection of musical tone effects. Either one of the first or second system is selected, and the memory circuit has a write switch arranged so that after completion of the writing of output signals of respective tablet switches by operation of the write switch, the memories remain unchanged by the writing, even by operation of respective tablet-shaped switches. The memory elements in the memory circuit of the first system are in a plurality of lines in conjunction with a plurality of line selection switches for selecting the respective lines of the memory elements. To select between the two systems, a plurality of gates open the first system while closing the second system when the line selection switches are selective operated.
