Patent ID: 7678985

Claim:
An electronic module for use in conjunction with a musical instrument, comprising: an enclosure with connector adapted for mechanical and electrical compatible insertion into a receptacle of first and second receiving devices each having a function usable in conjunction with the musical instrument, the function of the second receiving device being different from the function of the first receiving device; an audio input coupled for receiving an audio signal; a digital input coupled for receiving musical instrument digital interface (MIDI) data; a programmable control panel and display disposed on the enclosure; and an electronic circuit disposed within the enclosure and receiving user commands from the control panel and displaying configuration information on the display, the electronic circuit including, (a) an analog to digital converter coupled to the audio input for receiving the audio signal and providing a digital audio signal, (b) a microcontroller coupled for receiving the MIDI data and controlling routing of the MIDI data, (c) a synthesizer coupled to the microcontroller for receiving the MIDI data and generating a synthesized audio signal, the MIDI data containing information which is processed by the synthesizer to produce sound content of a first musical instrument or vocals contained in the synthesized audio signal, (d) a digital signal processor (DSP) coupled for receiving the digital audio signal and synthesized audio signal and generating a digital audio output signal based on signal processing of the digital audio signal and synthesized audio signal, the digital audio output signal being routed to an audio output of the electronic circuit, and (e) a memory coupled to the DSP, the memory storing the digital audio signal and MIDI data.
