PURPOSE:To secure generation of each musical sound featuring the corresponding relation to the operation of the key switch in a certain group and at the same time to give the high and low levels for the musical sound with every group, thus ensuring the aural identification for the individual operation key switch as well as the group to which the key switch belongs. CONSTITUTION:Both the individualization of the key switch operated at key input part 1 plus the group to which the key switch belongs are decided through operation key decision circuit 20. And with operation of ten-key 11, the corresponding musical sound is generated by musical sound generation circuit 25 and then applied to sound generator 29. And with operation of key 12 for four rules of arithmetic and function key 13, the musical sounds featuring the different frequencies from key 11 are generated through divider circuit 26 to be applied to generator 29. |
