The sound of the piano is something very complex. There are various elements to consider such as action, hammer, soundboard, sympathetic resonance, tuning age and even room reverb.
Some companies (such as Yamaha, Roland, Viscount and Modartt) have succeeded in realizing a realistic piano tone using physical modeling synthesis.
How did they achieve that amazing result? Where can I explore or even just get started with physical modeling? Searching online, I could only find incomplete scientific papers. Thanks in advance.
