Recreating a few sounds

Hi there,

I'm trying to recreate a few sounds in Pianoteq, but as a complete noob haven't been very succesful.

I use Pianoteq for playing live but sampled pianos for recording. I'd like to get close to the sound of my sampled pianos with my live sound and thus like to recreate them in Pianoteq.
Those are Cinesamples' Piano in Blue and 8Dio's 1969 Legacy. Both are Steinway D samples.
Has anyone recreated comparable sounds in Pianoteq?

Another sound I'd love to recreate is Nils Frahm's sound as recorded on the album "Felt". Would that be possible using Pianoteq?
