I have Synthogy Ivory II Grand Pianos. I did a lot of research before making the decision.
It contains a number of variations of Bosendorfer, German D and C7 - I mainly use C7
Pianoteq was in the list for sure, but Ivory won for me. The library takes about 80Gb of disk space.
I'd love to hear this one (Ivory II GP) in the comparison list.
Just curious.... is anyone doing any sort of EQ to the sample or are they raw wave output?
If I get some down time today, I may take a minute and use the CSC synth with the Steinburg piano (or two) so you can see what $20 gets you.
