I recently purchased the befaco AC/DC. It was perfectly recognized by my macbook wihtin ableton, only the noise floor was very high but it worked.
My problems is now, that my computer (osx) does not recognize the module (as audio interface) anymore. By powering up my case the module shows the usual start up animation, so I think everything is alright. I tried to restart the computer and the eurorack case, dis- and reconnected but nothing brought it back.
