Hi, IÂ´ve got Logic Pro, OS X 10.7.4 on a MacBook (early 2008, FW400), and have been using several interfaces (RME, Focusrite Saffire, Edirol) with no problems. IÂ´m now going to record some some youngsters, using the equipment in a preinstalled rack at the location. I dropped by today to check out the equipment. The interface was a Digidesign 003 Rack+, with a Focusrite OctoPre II attached. In Logic, the interface showed up in the Audio Preferences, and all inputs (and outputs) showed up nicely, so I made a template ready with named tracks on channel 1-16. To check the monitor routing, I then imported a mp3-file, but there was no sound, including that the level meters on both the track and Stereo Output was dead. When switching to Build-In Output and input, the mp3 played back and the meters ran as expected. As my time is very restriced tomorrow, I wonder if installing the Digidesign 002-003 familiy driver should be enough for solving this issue (which I did after returning home), or are there any preferences I should check as well? ..or should I expect that it wonÂ´t work because of inadequate drivers? I have a RME Fireface 800 at home, and borrow a Presonus Digimax D8 (with 8 direct outputs), which I think IÂ´ll bring in backup, but IÂ´d be very happy if I could solve this with the already present (and patched) equipment. Thanks in advance!
