A system to reproduce the sound of a stringed instrument

A system (1) used to reproduce the sound of a stringed instrument provided with hammers striking the strings is disclosed. The system comprises speed detection means coupled with each hammer to detect the percussion velocity on the string, a plurality of note modules receiving in input a signal representative of the hammer velocity and generating a force signal (Ftot) representative of the global partial components of the string vibration, and a soundboard-instrument body module (700) receiving in input said signal of the global partial components (Ftot) from each note module and generating two electrical signals (left, right) adapted to drive two electroacoustic transducers for sound emission
