I'm having a strange problem. I'm hearing 2 voices on my lead vocal track when there should only be one. It only lasts for a split second. I've checked all my other tracks to see if they may have been armed while I was recording, but that wasn't the case. What's even stranger is when I mute my lead vocal track I don't hear the second voice. What's even more strange than that is when I solo my lead vocal track or the buss that's carrying it's affects, I don't hear the second voice either . I'm out of options. Help!
