Berhinger UMC 404 HD
Hello, from Paris, Excuse me my english is not very good could you tell me if the Berhinger UMC 404 HD is compatible with OSX El Capitan and Logic Pro 9 Merci beaucoup Cordialement DLD

At least in theory: yes — the UMC404HD is compatible with your setup.
In practice: it may or may not “just work” — because of Logic 9’s age, potential USB-bus quirks, and the lack of a dedicated driver to fallback on.
