Disclosed is a stringed instrument that includes a plurality of strings and a pickup to which each of the plurality of strings is respectively coupled that is connectable to a computer to implement DSP modeling. A serial interface circuit is coupled to the pickup and to a digital connector that formats each digital string vibration signal received from the pickup into a digital serial protocol. A computer is coupled by a serial link to the digital connector such that the computer receives each serially formatted digital string signal (SFDSS). The computer operates at least one audio DSP-based software module to process each received SFDSS wherein each SFDSS is processed in order to emulate a corresponding string tone of one of a plurality of stringed instruments to create an emulated digital string tone signal (EDSTS). Each EDSTS is then transmitted back over the serial link to the stringed instrument for playback.

Stringed instrument for connection to a computer to implement DSP modeling

Disclosed is a stringed instrument with embedded DSP modeling capabilities to model an acoustic stringed instrument. The stringed instrument has a body and a plurality of strings and each of the plurality of strings is respectively coupled to a pickup to detect a vibration signal for each string. An A/D converter converts the detected vibration signal of a string into a digital string vibration signal. A DSP is located within the body of the stringed instrument to process the digital string vibration signal and to implement an acoustic modeling system to process the digital string vibration signal in order to emulate a corresponding string tone of one of a plurality of selectable acoustic stringed instruments. Acoustic modeling includes acoustic string and body modeling, microphone placement modeling, and pick-sound modeling. The emulated acoustic digital tone signal is then converted to analog form for output to an amplification device.

Stringed instrument with embedded DSP modeling for modeling acoustic stringed instruments

A data transmission system comprising a transmitter and a receiver that use a single external word clock to generate all needed clocks locally using a clock generator and a phase locked loop. Data words are transmitted on a transmission line based on a single transition of the word clock. The transmitter and receiver may each be incorporated on a single chip.

Serial data transmission system using minimal interface

Disclosed is a stringed instrument with embedded digital signal processing (DSP) modeling capabilities. The stringed instrument has a body and a plurality of strings and each of the plurality of strings is respectively coupled to a pickup of a polyphonic pickup. The polyphonic pickup is used to detect a vibration signal for each string. An A/D converter converts the detected vibration signal of a string into a digital string vibration signal. Further, a digital signal processor is located within the body of the stringed instrument to process the digital string vibration signal. Particularly, the digital signal processor is used to process the digital string vibration signal such that the corresponding string tone of one of a plurality of selectable stringed instruments may be emulated. The emulated digital tone signal is then converted to analog form to create an emulated analog tone signal for output to an amplification device.
