The typical Disklavier is a real acoustic piano outfitted with electronic sensors for recording and electromechanical solenoids for playback. Sensors record the movements of the keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF).
Thyristor. Introduction: Thyristor is a three terminal device with four layers of alternating P and N type material (three P-N junctions). The three terminals are Anode, Cathode and Gate.1  The Thyristor is mentioned as Silicon Controlled Rectifier (SCR) as it is made up of silicon and working as controlled rectifier.he thyristor has a unique four layer construction of alternating P-type and N-type regions. It is given below: The SCR looks like two PNP transistor connected in a back to back manner. It can be understood with the reference of above figure.
