Claim:
1. A system for determining fretted positions and note onsets of a stringed musical instrument having a bridge, a neck comprising a plurality of frets, and at least one instrument string, the system comprising: a voltage applicator configured to apply a voltage to at least one fret of the plurality of frets; a fret multiplexer configured to electrically connect to the at least one fret of the plurality of frets of the stringed musical instrument; a bridge multiplexer configured to electrically connect to the at least one instrument string at the bridge of the stringed musical instrument; a voltage analyzer configured to compare a voltage of the at least one instrument string electrically connected to the bridge multiplexer to the voltage of the at least one fret of the plurality of frets electrically connected to the fret multiplexer, the voltage analyzer being further configured to output a voltage analyzer output signal; a compressor configured to receive the voltage analyzer output signal and to process the voltage analyzer output signal to form a compressed output signal; and a processor configured to receive the compressed output signal, to coordinate string and fret scanning and analysis, and to output at least one of a processed output signal and a multiplex control signal.
