You know how most virtual pianos are based on samples from real pianos? Well, Pianoteq decided to take a different approach, by simulating an actual physical piano. As in, their software simulates all the reverberations, the strings, the hammers, the cabinet. Everything. No samples. Which means everything is adjustable. You can simulate the piano tuned in different temperaments, with the lid open, closed, or half-open, the length of the piano, etc.
