ABSTRACT:
A sound synthesizer for a plucked string instrument simulates noises and transients produced before and after and during the transitions between notes. A particularly convincing synthesis of a plucked string instrument is produced by combining the transients into the final output. In particular, the transient tap tone and longitudinal vibration of the string resulting from the string pluck, and the damping tap tones resulting from the string damping, are all simulated. In one embodiment, the tap tone created upon attack and plucking of a string, is synthesized, and then used to stimulate a resonant circuit, thereby simulating both the pluck tap tone, and the transverse vibration of the string. In addition, the final damping transients which occur at the end of an articulated note are also simulated, using either an independent transient synthesis section, or by stimulating the resonant circuit with a tap tone, while simultaneously re-tuning that resonant circuit.
