With my Mac using OS 10.5.8, I find that I often have to restart the computer to restore signal after changing interfaces or programs. If I use Logic and then quit and switch to Ableton, I'll find my MAudio interface (FW410) is not sending signal. So I restart the computer, and then things are fine. regards BobC |
