Helpinstill Piano Sensor
The Helpinstill Piano Sensor uses a patented method to track the vibration of the strings of a piano. Putting that electrical signal into a speaker happens to duplicate the sound of the piano, but without any other instruments around the piano being picked up. The Helpinstill also permits the piano to be amplified at high volume levels without feedback, since the system doesn't rely on air waves within the piano.
