The two stage decay can be observed in the simplified case of two strings vibrating in the fundamental mode. Things get more complex when you consider three strings and all their overtones. Then it’s not a two stage decay but rather a multiple stage decay.
Simplified? That must be relatively speaking .
I had wondered why AAS's Strum Acoustic modelled virtual guitar did not have a 12 string in it. That's why I don't have it. What I see when tuning up with Strobosoft's (virtual!) tuner, is that in a real 12 string the courses have different amounts of inharmonicity, depending on the physical structure of the strings. Being able to see (and hear) changes of 1 cent is not so helpful to tuning up when the harmonics can be 10 cents away from the fundamental, and the fundamental is "wobbling". Guitarists, of course, can pluck the strings anywhere along the length, and use different things to do that, but an acoustic 12 string remains a sorry business. It's lucky that pianos do not have a lever to move the hammer bed around, and a dial to bring different hammer materials into use.
Back on topic, it's nice read professional pianists' views. I note from its reviews that PTQ has achieved a lot of interest from serious players (the present writer not particularly included). It does not, and should not, follow that the "seriousness" of a product is related to the perceived "seriousness" of the decision to buy the product. Anyone thinking that should at least never buy coffee at British motorway services.
