Abstract:
1. Pianoforte instrument comprising: an action with keys and including strings which are struck via a mechanism when the keys are actuated and are made to vibrate; a sound board to which the vibrations of the strings are transmitted; a sensor associated with each action for detecting actuation of only the associated key and for recording corresponding movement of the key to generate an individual sensor data signal; a delivery device including a drive means for delivering additional vibration energy into the sound board; and a controller for receiving the sensor data signal to, in turn, control the drive means; said controller including a sound-augmenting device to which the measured values of the sensors are supplied, said sound-augmenting device including a memory device for compiling data corresponding to a desired sound characteristic in dependence on the measured values detected by the sensors and including a partial tone spectrum for each selected tone; and wherein the sound-augmenting device supplies the sound board with additional vibration energy, corresponding to the data obtained, via the drive means.
