I did a vocal on track 1. I'm trying to record a B.G. vocal track on track 2 in Logic 9 When I plug into track 2 on my interface [Motu 828 MK 2] I can hear myself and an audio file appears to have been recorded in Logic on channel 2...... But nothing plays back on track 2. No effects/compressors etc, seems to work on track 2 or 3,4, etc... either. Track 1 seems to be the only one recording and playing back. I tried erasing and creating a new track but same problem. Anyone know whats wrong here ? thx
