Hi Sam.
Thanks for the reply. Yes I am using closed back quality headphones and there is a little (very little) leakage but nowhere near what I am getting in the playback of what I have recorded.
When I playback just the vocal track with all others red-x'd out the music that has been also recorded is much louder that the recorded vocal on that vocal track.
So must be in some setting I have that just is not right in PT.
