I recorded one track for the main vocal first. Then another performance track doubling the chorus parts only. I did one rough pass to include the main vocals to the levels-only mix. When I was happy with it, I proceeded to do the back up vocals. I used the same POD Farm vocal preset but adjusted the reverb module to increase the depth and make the back up vocals sound farther from the main vocal. I duplicated the back up vocals and panned them left and right.
Here's a clip.
Levels-and-Panning-Only Rough Mix including Vocals
So far so good :)
I'll let it stew for a bit to give my ear a rest and listen to it a few more times. Then I'll make a final decision whether to proceed with the mixing segment.
