Are there any papers on the mathematics of the modelling that Pianoteq uses? I know that my be proprietary, but perhaps there are some overview articles?
I saw a video where they go to a factory like Kawai and record lots of samples, just as a sampling VST make would do. How do they get to the modelled VST from the sample set?
My background is in mathematics so I was delighted to see Pianoteq came from a maths department in France.
The best clue is probably the patent description, where the tl;dr is (if I remember correctly) that the individual strings are assembled by additive synthesis, and the resonance is a spatial arrangement of waveguides.
Nothing super unique in the general approach, so the secret sauce probably lies in the excellence of execution: which inharmonic frequencies to excite when, what to allow to crossbleed, etc. For example v9 seems to have tuned the waveguide mesh to new heights
Where would one find the patent?

Thank you. That's very interesting. I spent some time thinking you can't patent software or algorithms (as far as I know, still), but the patent gets around that by presenting a 'device'.

The latest paper on the subject is from late 2018 ; the document explains how Pianoteq uses modal synthesis starting from paragraph 4.2

Great source and well written - thank you for finding!
