Hello Benjamin,
Of course, you may "try" to recreate a Bösendorfer 290 from a Pianoteq D4, but I am going to offer you factual information as to why that feat is essentially impossible to do. True, Pianoteq's D4 and the B290 have extended keyboards, but that's where the similarity ends.
As a person who has performed on an authentic Bösendorfer 290, and who has witnessed how the B290's piano case is constructed, it is the difference in construction that prohibits making a D4 .fxp sound indistinguishable from a B290. If one were to rap your knuckles on a Steinway Model D's piano case, you would almost break your hand because the Steinway's construction is so robust. This is by design. In fact, a Steinway's piano case is constructed by gluing together several long plies of wood (I believe over 26' in length) and having numerous burly black guys "muscle" the plies into place around a piano-case-shaped "mandrel", using muscle and aided by hydraulic jacks. (Sorry for the "black" reference, but NY Steinways are made in Queens NY exactly that way ... by laborers who have the "mentality" for manhandling wood -- at least for the piano's case. No complaint is made about the other artisans who work for Steinway in Queens NY or Hamburg Germany.)
Now, contrast a Steinway's construction with a Bösendorfer 290's construction: Instead of manhandling several parallel glue-covered plies of wood around a mandrel, a Bösendorfer 290's case consists of a SINGLE thick piece of wood, into which a great number of sawblade cuts (called "kerfs") have been introduced into what becomes the inside of the piano's case. By introducing these almost-all-the-way-through kerfs, the single piece of wood is flexible enough to be bent into shape without hydraulics and burly manpower! Once into shape, a team of artisans proceeds to glue "wedges" of wood into the bent openings left by the bending process. This results in a wooden construction that is much less "stressed" as the Steinway product.
The end result is this: When one raps his knuckles against a Bösendorfer 290's case, it will sound akin to rapping the body of a 'cello or contrabass -- instead of a knuckle-breaking thud when doing the same thing to a Steinway Model D's piano case. This difference is made with the specific intention of the Bösendorfer's piano case to act as a resonator!! Thus, a Bösendorfer's sound is more "singing" than a Steinway's sound, but it does not have the sheer raw power that a German- or New York Steinway D has.
Hope this helps.
Cheers,
Joe
