Abstract

PURPOSE: To always ensure the correct reproduction of the key operation timing of the recording time by selecting the frame into which the key signal is inserted in accordance with the intensity of keying.
CONSTITUTION: The output of switch circuit 2 generated through the key operation of keyboard 1 is supplied to key detection part 3a and intensity detection part 3b each. And the output of parts 3a and 3b are supplied to microprocessor 6. At microprocessor 6, the bit corresponding to the key pressed strong among the key signals is excluded from other bits in the same frame to be then inserted to the subsequent frames. And the frame to which the bit is to be inserted is decided according to the scale of the intensity signal. Thus the key to be pushed strong starts in the proper time after starting the key to be pushed softly. As a result, the actual keying is carried out simultaneously, thus ensuring the correct reproduction in the key operation timing of the recording time.
