I'm using an M-box to record into logic express, and i can hear the instrument when they are played, (but no send effects) through logic, and i see the waveform when i record, but when i press play theres nothing. My ins and outs seem to be right, and this problem just sprung up over night so i'm pretty sure i didn't mess with any settings. When i switch the audio driver from the mbox to internal output i can hear it, but i shouldn't have to do that every time i want to hear something.
