I have a Standard license (bought at v7 launch) with Steinway D, Petrof and Grotrian models.
Having tested quite a bit the v8 demo I'm also considering about buying the Steingraber.
The default "Steingraeber E-272" preset sounds amazing on any situation (personally I disable pedal noises and reverb, so sound engineers have a drier signal to work on mixing).
Personally, I don't look for a specific piano sound or sound situation... instead I tend to look for a "allrounder" sound that works on many situations, a little classical here, some latin comping there, pop comping, some solo parts... and that Steingraeber E-272 is versatile as hell.
The licensed pianos I got so far:
Steinway D: is a good allrounder, 2 pianos for 1 license and nice presets to work on. Still trying to get a brighter low end, a little bit muffled on some latin comping, but just a little. Tried some FXP posted (with the morphing fever that come with v7 launch there are some decent presets posted) find some good ones, but not spot on for the allrounder sound I look for.
Petrof: is just decent. Also 2 pianos with 1 licens but no much love for the "Ant. Petrof 275", but the "Mistral Jazz recording" preset sounds gorgeous on studio monitors (but a little bit bright for my taste on headphones).
Grotrian: ... almost never used. Can´t find right balance between lower end, muffled and muddy.
Best regards from Spain!!
