Thanks a lot for all the replies! Summed up they give me a much better idea of Odessa. Extra thanks to Nick, your explanations were really helpful as I really am just at the beginning of my journey and trying to grasp the basic concepts of sculpting sound with a modular system.
The Odessa is deep but (because of it?) a fascinating module. Maybe I should've started out with a simpler OSC but I couldn't resist it!
