Patent ID: 8865992

Claim:
A sound manipulator comprising: a touch sensitive sensor arranged to detect finger tapping that comprises finger contact upon the touch sensitive sensor (“touch”) and finger detachment from the touch sensitive sensor (“release”), and to generate a corresponding time-dependent tapping signal comprising a first state corresponding to periods in which the finger contacts the touch sensitive sensor and a second state corresponding to periods in which the finger does not contact the touch sensitive sensor; and a processing unit arranged to: receive an electric audio signal associated with an instrument that is played during the finger tapping; receive at least one state change characteristic; modify the time-dependent signal corresponding to the finger tapping according to the at least one state change characteristic; and multiply, with a common time base, the modified time-dependent signal with the electric audio signal, to yield a modified electronic signal, wherein changes of the modified electronic signal during changes between the first and the second states of the tapping signal are characterized by the at least one state change characteristic.
