His Star Wars mockups with it are also fantastic.
IMO, at least where orchestral mockups are concerned, Noteperformer is the way forward. It's just way easier to compose with than dealing with massive templates of samples.
The big problem, as I see it, that still plagues "traditional" sample libraries that you load in a DAW is a lack of homogeneity between different articulations. For example, Cinebrass records 1/8, 1/4 and 1/2 notes. But I find that going from 1/8 to 1/2, or 1/4 to 1/2 results in a "wrong" sound most of the time. Because most of the half-note samples were recorded with a softer attack than the other two. This kinda thing makes it harder to sequence a truly-musical line. Don't even get me started on switching between totally different articulations and repeated notes even with RR.
But something that was more "keyboard" sounding did precisely because it had too much homogeneity between the samples. Like, a "staccato" was often just a cut-off version of the sustain. It was only one sample. The upside to this is that sequencing rhythmically-active lines and still sounding cohesive is a lot easier and thus, I argue a lot of these composers write better music because they're not being limited by "what the samples are good at".
Example with older Noteperformer:
New Noteperformer
It's not perfect, but sequencing something like that with a DAW with most of the sample libraries available is a nightmare, and very time-consuming. I personally think that this kind of tech will soon make it so that you can just compose in a notation program and it will sound just as good as labor-intensive mockups with with the best sample libraries, but in a lot less time.
