Thanks Sundance,
So what I am doing is this.
I am mixing all the tracks with the vocals in and arranging all the instruments to suit the vocals.Then can I just render the two separately and blend them in later?.I am finding my backing track is working out great without the vocals but as soon as I mixdown everything together with the vocals in it is not as good ,
The vocals dont seem to have the separation I hear when I listen to a pro song even though I have unmasked the vocal etc from interferring freq etc and have left room for the vocal with panning etc.
When I listen to a pro song the vocal seems to sail along on the top the backing track while still anchored to the backing track.
This is why I am wondering could it be better to attach the two after the mixing process and before the mastering but having mixed the instruments with the vocal in for the mixing process,thanks again H
