Hi. I'm trying to use Logic Pro 7 with a Macbook Pro, and I get no sound. The midi seems to be working fine. I get visual feedback that the songs are being recorded. But no sound when I try to play them. My sound system seems to be set up correctly because I can record and listen to songs with the Garage Band editor that came with the Macbook. Someone told me Logic 7's sound system doesn't work with Macbook Pro. Is that true? If so, is there any kind of patch or workaround to make it right? Help! I need Logic 7 to open a ton of old files created on a PC.
