That. and a a head-start of years of CPU optimizations. The model of strings and resonances inside a body are also well understood. There are also lots of publications on the subject. It's still far from trivial to get this right, but still. As you said, the degrees of freedom on a piano are far less than those on a drum, also prior state of the instrument is a lot more complex for drums, particularly cymbals and drumrolls. > pianoteq is a wonderful sounding instrument.

It's an awesome piece of engineering. ciao, robin
