A Parametric Piano Synthesizer

A discussion regarding the structure of a piano synthesis model as well as its various components are given followed by the implementation of the synthesizer with the use of PWGL software. The model includes a loss filter, a dispersion filter, a simulation of the beating effect, a simulation of the sympathetic resonance effect, and a block that produces the knocking tone simulating the hammer strike. The model uses a digital waveguide synthesis technique and it was developed with the use of methods that enable real-time control of the parameters. This proposed piano model differs from others with its excitation process and with its real-time control over the inharmonicity. AS for its implementation, the synthesis model can be controlled with a MIDI keyboard or a notation tool.
