Setup is really easy. You can try the demo, which will tell you sound and the setup for the demo is the same as the paid version. No extra sample folders to manage, it's all packaged together. If you purchase, you just register/authorized your demo installed.
It's quite similar in sound to either Hauptwerk Cavaillé-Coll but with more stops (if I'm remembering correctly), as it's based on one of Cavaillé-Coll's organs.
