Model-based digital pianos: from physics to sound synthesis Bal´azsBank, Member, IEEE and Juliette Chabassier∗yz October 12, 2018 Abstract Piano is arguably one of the most important instruments in Western music due to its complexity and versatility. The size, weight, and price of grand pianos, and the relatively simple control surface (keyboard) have lead to the development of digital counterparts aiming to mimic the sound of the acoustic piano as closely as possible. While most commercial digital pianos are based on sample playback, it is also possible to reproduce the sound of the piano by modeling the physics of the instrument. The pro- cess of physical modeling starts with first understanding the physical principles, then creating accurate numerical models, and finally finding numerically optimized signal processing models that allow sound synthesis in real time by neglecting inaudible phe- nomena, and adding some perceptually important features by signal processing tricks.
