ABSTRACT:
A touch responsive keyboard musical instrument is provided with an array of keyboard switches arranged in octave groups and connected in parallel octaves. A motion transducer is attached to each keyswitch so that a transducer signal is generated corresponding to the motion used to actuate the keyswitches. The keyswitches are sequentially scanned until an actuated keyswitch is detected. At this time the scanning is interrupted until the corresponding transducer signal has reached its peak value. The peak value is used to vary a tonal effect such as a frequency modulation or an ADSR envelope modulation of a tone generator assigned to the actuated keyswitch. The keyswitch scanning is resumed when the peak value of the transducer signal has been measured.
