An acoustic control system for an electronic musical instrument, which can obtain optimal acoustic characteristics irrespective of whether or not a low range speaker is attached to a body thereof. A piano body has high range and mid range speakers. A low range speaker is removable from the body. A stand-excluding switch designates a first speaker-use mode for using the high range and mid range speakers alone, and a stand-including switch designates a both speaker-use mode for using both the high range and mid range speakers and the low range speaker. A ROM stores stand-excluding and stand-including factors for setting acoustic characteristics in the two modes, respectively. A CPU reads one of the factors, which corresponds to the mode designated by the stand-excluding or stand-including switch. A tone generator circuit generates a musical tone signal to be reproduced in one of the modes, based on the read factor.

A Sensor glove is an instrument, in the same way that a piano is an instrument. The Sensor glove is purchased and the owner then learns to use it and the sensors therein to develop the performance of a sound, character or model, or to “conduct” or “play” the sensor movements and experience the response of the model in real time. Several performers with a number of the Sensor glove can control over 200 motors or hundreds of control points on a character at one time, manipulate audio data, or computer images etc. The characteristics of the sensors on the gloves can be adjusted to the needs and demands of the wearer or the many performer and wearers in those venues where multiple performers are used with many gloves to control or produce the motions and sounds of many distinct characters in a screen play.

The corresponding key produces a sound corresponding to the note when played. The name of the note is pronounced by a narrator or some other character. The note is visually identified on the staff by the narrator or some other character. The note is also associated with the corresponding key. Association may entail generating a note character and associating the note character with the note and key. A sound corresponding to the corresponding key is played.

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.
