RIP Actually we do know that they do exactly that. They have said that to create a model (say the new Bosendorfer) they just turn a bunch of knobs (which are not available to users, not even in the Pro version) and here the model comes.
Well, that is the exact explanation behind why Pianoteq need the endorsement. Without it many people might be unwilling to spend money on what is supposedly a minor tweak they could’ve done themselves. Whereas an official “blessing” seals the deal for them. Imagine you’re a customer, you hear a new sound that Modartt is selling you as a “Steinway”. How do you know it’s actually a Steinway? It can be anything 😃 So, if Steinway blessed it (for money) it suddenly becomes a Steinway.
It’s also why sample piano manufacturers don’t need to purchase any approval or brand sticker, as I explained before. Because unless you think they EQ-ed some of their existing samples, the basic purchaser trusts that they really sampled the actual piano. Any endorsement will cost money and it’s dubious it will improve the sales.
So, with Pianoteq endorsements it’s a bit of everything: Modartt need it, piano manufacturers get some money and Pianoteq sounds good to the general public. It’s a mutual benefit.
However, I wouldn’t draw any extended conclusions from a mutually beneficial deal like the one between Modartt and piano manufacturers, such as e.g. how superior PT must be to “earn” big names’ endorsements. As I pointed already, it’s a special need for Pianoteq to be endorsed. Sampled developers don’t have that need.
