Hi, I get signal in the monitor window of my DP03SD when I plug my mic. in to record but get no sound out of headset or studio monitors and it does not record my vocals on either tracks 7 or8 when I am in record mode. I hear my voice and I get signals from the other tracks when I switch to flashing red record mode.Why is this? Can I not record on tracks 7 and 8 are they only used to bounce tracks and not to record? I do not want to lose my instrumental parts on tracks 1 through 6. I wanted to save the vocals for last! Thanks!
