Topic: Request: change string tension, stiffness, diameter, inharmonicity etc
This is a request for future versions of Pianoteq, and one which hopefully is not too difficult to implement.
Many of us are interested in listening to what the piano would sound like as the tension and stiffness vary. What happens if we put thinner strings on a grand piano and lower the tension to get the same pitch, for instance? Or what happens if we somehow magically lower the string stiffness? The stiffness pretty directly changes the inharmonicity; the tension, though, is much more interesting...
I know that tension is somehow already built into the Pianoteq algorithm because when you do microtuning, it has the "String Tension" and "Full Rebuild" parameter. So that's one way to play with the tension right now, which is just to lower the pitch and keep it on "String Tension" mode. Of course, we would like to change the tension without also changing the pitch...
There are, of course other parameters - string diameter, wound/unwound, density, etc. Many of these directly change the inharmonicity and not much more. So we don't need to have every parameter. But it would at least be nice to change the tension and stiffness/inharmonicity, at least. Perhaps not even stiffness is necessary because "scale length" already does that. But tension would be very interesting. Could we add this to some future version?
