Hi, I hope someone can help. I use a BOSS RC-50 LOOP STATION, a M-AUDIO INTERACE, and I use LOGIC 9. What Im trying to do is use Logic to record myself playing some tracks live on the Loop station. I can get the interface to clearly hear whats coming through the loop station but when I try to hear it through the head phones on my mac in Logic, all I get is a high pitch squealing sound. Does anyone know if this can be fixed and if so how??? Thanks in advance for any help.
