This may be a bit specific for what this forum is for, so I'll apologize now if I'm posting in the wrong place. I'm running into some output issues while trying to record my band. Here's the run-down: I'm running a PreSonus FP10 to my MacBook with OS X 5.7.blahblah.blah, and when using GarageBand everything comes in and out fine, monitoring included. This morning, I picked up my first copy of a real recording software: Logic Express. Now, using the EXACT same interface and setup, we can get input into Logic, but when I try to monitor or play it back, with everything still hooked up, it does not work. I've done some research and lurking and tried some stuff I've found out, but so far no luck. Creating an aggregate audio device that couples the onboard speakers with the PreSonus as input did not work, neither has double-, triple-, and quadruple-checking the settings in Logic to make sure it's all set up to play out of the speakers. I'm at a loss! Any help would be greatly appreciate. tl;dr Running a PreSonus FP10 to MacBook with Logic, getting input but no output, anyone got advice?
