ABSTRACT:
In an electronic musical instrument capable of producing a key touch feeling resembling one in playing the piano by the provision of a hammer which is interlocked with a key, key-on data and touch data are generated in response to downward displacement of the key. In this type of electronic musical instrument, key-on data and touch data are also generated when the hammer is displaced upwardly and downwardly due to bounding of the hammer independently of the movement of the key. A touch control characteristic is established usually by using touch data generated in response to key-on data. When, however, second key-on data has been generated within a predetermined length of time after generation of preceding first key-on data, a touch control characteristic for the second on data is established by using first touch data generated in response to the first key-on data. By this arrangement, a touch response control of a tone signal corresponding to the second key-on data generated due to the hammer bound is made in accordance with the first touch data corresponding to real key touch during depression of the key.
