Abstract
An electronic keyboard simulates the keyboard action of one or more acoustic pianos and/or organs. Sensors associated with each key capture the force exerted on the key, the speed of the key and the position of the key to compute an amount of force to apply in feedback to the depressed key. An actuator associated with each key provides the computed feedback value as a counter-force to the player's finger pressure. Feedback may be computed in one or more processors by applying the sensor readings to a system model of the desired instruments mechanical key action. Also, feedback may be determined through a lookup table containing feedback values defining a particular instrument's action. The player can switch between different instrument action definitions as desired, and may tune certain parameters to achieve a customized action.
