Patent Images
1. A computer interface for a polyphonic stringed instrument, comprising:
- an analog interface configured to receive a plurality of individual analog audio signals, each analog audio signal corresponding to one of a plurality of strings of the stringed instrument;
analog-to-digital conversion (ADC) circuitry configured to convert each of the analog audio signals to a corresponding digital audio signal;
a processor configured to combine the digital audio signals into a single serial data stream; and
a serial data interface configured to transmit the serial data stream to a computer system.
