I've been noticing more and more with garageband that I can spend an hour mixing and editing, only to export it to iTunes and have it sound like trash. Has anyone else experienced this? Does anyone know how to fix it? It seems to lose a lot of mid range mostly, but it also just sounds worse in every way.
