ABSTRACT:
A digital interface apparatus is provided for use in an analog musical instrument capable of generating an analog audio signal, and is designed for interfacing with an external digital audio apparatus. In the digital interface apparatus, an input/output interface converts the analog audio signal generated by the analog musical instrument into a digital audio signal. The input/output interface has an input terminal and an output terminal for transmitting the digital audio signal to the external digital audio apparatus and for receiving a digital audio signal from the external digital audio apparatus. A digital signal processor processes the digital audio signal which is either converted from the analog audio signal or received from the input terminal. A main controller controls operation of the digital signal processor according to instructions. An operating member is manually operated to provide the instructions to the main controller.
