PURPOSE:To simplify the work of a user when an extension sound source is connected to an electronic instrument by discriminating the kind of the connected extension sound source with the electronic instrument and automatically performing control suitable for the kind. CONSTITUTION:This device is constituted so that a CPU 10 controls the whole operation, and the sound source 24 incorporated in the electronic instrument is set as the sound source for generating/interrupting a musical tone signal based on sound generation instruction information/muteness instruction information corresponding to the operation of key board device 22. Together with that, the extension sound sources (A) 28 and (B) 30 are set as the extension sound source connectable for extending the sound source. Then, by a discrimination means, the kind of the extension sound source connected to the electronic musical instrument capable of extending the sound source is discriminated, and a control means controls the sound source according to the kind of the connected extension sound source. Thus, the control suitable for the kind of the extension sound source is automatically performed, and the work of the user when the extension sound source is connected to the electronic musical instrument is remarkably simplified. |
