ABSTRACT:
A method and apparatus for controlling a keyboard operated device having a plurality of keys includes a plurality of sensors associated with each key. Each sensor detects a different one or more attribute of the nature of actuation of the key. Each detected attribute is used by selection circuitry to form a characteristic of the device's response to actuation of the key. The individual characteristics are combined to form a response to actuation of the key. The response may be an output signal or may be further processed internally by the device. In a preferred embodiment the invention is part of a musical synthesizer. One sensor is arranged to detect actuation of a key, while a second sensor is arranged to detect which finger actuates the key. The detection of actuation of a key is used to control the pitch of the resulting output. The detection of which finger actuates the key is used to control the timbre of the resulting output signal. Pitch and timbre are combined by a sound generating device and an audible note or group of notes produced. Other embodiments using the combined characteristics include security systems and computer input devices.
