摘要： A detection system is provided for detecting a musical note played on a string instrument having a fretboard provided with a plurality of conductive frets and conductive strings. The system includes at least one conductor coupled to each of the frets; an inverter having a first terminal coupled to the conductor and a second terminal coupled to the conductive string, the inverter being configured to logically invert a signal transmitted therethrough, such that when the conductive string is pressed against one of the frets allowing thereby for a signal to be transmitted therethrough, the signal is sequentially inverted between two logical states at a frequency being dependent on the distance between the inverter and the fret; a frequency detector configured to measure the frequency; and a controller configured for determining the location of the fret along the fretboard in accordance with the frequency, and to thereby detect the musical note.

摘要： A floor effect unit for actuating a musical effect device is provided. The floor effect unit includes a base plate having at least one electrode configured to collect electric charges; a conductive plate having at least one pressable portion configured to collect electric charges having a polarity opposite to the polarity of charges collected on the electrode, pressable portion being configured such that pressing thereon reduces the distance between the at least one pressable portion and the at least one electrode changing thereby the capacitance therebetween; and a spacer disposed between the base plate and the conductive plate and being configured to provide dielectric gap therebetween, a printed circuit board coupled to the at least one electrode and the conductive plate and being configured to generate an output signal for operating the musical effect device in response to a change in the capacitance.
