I am new to Logic Express 9. I have a iMac and my projects play audio either via my headphones (which are plugged into the iMac) or the Bose Companion that is plugged into the USB port. I control this via the Preferences/Audio. Sometimes switches causes Logic to crash. My question is how to I get both to play at the same time? I find that I want to hear my projects through the Bose, which is superior sound and the head phones at the same time. Any help is appreciated. I am a good student! Thanks!
