Abstract
An electronic musical instrument with a game function is capable of being used either to play music or to play a ball-hitting game. The electronic musical instrument comprises a keyboard having a plurality of keys for generating a first key data which is supplied to a musical tone generating circuit for producing a musical tone corresponding to the first key data, thus enabling to play music in a conventional manner. In addition, the electronic musical instrument comprises for use in a game mode a data generating circuit for generating a second key data representing a pitch of a key and varying its pitch in either one of directions to sequentially take a higher and a lower pitch respectively. The second key data is supplied to the musical tone generating circuit for producing a musical tone, thus simulating the movement of a ball. The second key data is compared with the first key data to generate a coincidence signal when both key data substantially coincide with each other. The coincidence signal causes the data generating circuit to make the second data vary a direction of the pitch variation, thereby enabling to simulate a ball-hitting. Other associated circuitries for controlling a ball speed, scoring and displaying a point, and the like are also provided.
