2) You have to use two tracks on your eds submix.
3) Copy your vocal track from track 1 to track 2 (same wavefile)
4) Use the stereo (x) on your paris vst section before opening Chainer at vst insert on track 1.
Thus you will have a stereo instance of chainer applied on tracks 1&2 aka your vocal track.
5) Open vst reverb plugin
6) Now use the wet/dry option in chainer to introduce the dry vocal sound as much as needed
That is it !!
Enjoy and let me know.
