Bug? Significant inharmonicity even with 10m piano

Thanks. So based on what I am measuring, and hearing, and what I am seeing in those other posts, the "String Length" parameter has a significant audible effect mainly in the lowest notes, which lessens rather quickly as you go up the keyboard.

I would very much like to be able to reduce the inharmonicity to 0 - either via "string length" or some other parameter - for *every* note.

FWIW, for the "B4" I had above, the measured coefficient changed a little bit from 2.72m to 10m, but not really significantly. At 10m the coefficient was 0.000854634239097124, whereas at 2.72m the coefficient was 0.000983605660911475. So slightly less, but not far from zero.

These are the measured cents deviations for both, for reference.

You can clearly see that there is slightly less inharmonicity for the B4 note at 10m. However, even at the 10m level, there is still significant inharmonicity. This inharmonicity is clearly audible and I would very much be interested in listening to what it would sound like with no inharmonicity at all.

Now, this is just for the B4 note. As you get towards, for instance, a bass C0, then the difference is much more significant; there is about a 10x change in the inharmonicity coefficient. So I suspect that the "string length" parameter is kind of following the basic shape of a grand piano body, lengthening the bass strings but not the treble ones as much. So it would be very interesting to let the treble strings be lengthened also. (Note that I did have everything lengthened to 10m in "Note Edit".)

So I guess this is a feature request:
* To either make it possible to increase the string length beyond 10m
* Or make it possible to adjust the "curve" of the piano (so the treble strings aren't so much shorter than the bass strings)
* Or just give some other way to adjust the inharmonicity directly on the treble strings (and all the strings).

Would it be possible to just let this slider go to extreme values, like 1000, or even "infinity"?
