Did you ever find an answer or solution to this? I am having the same issue, except my setup is a little different.
I am running an H9, TimeLine and Big Sky (in that order) into an RJM mini line mixer that is all after(POST) a Two Notes Torpedo Live. So Kill Dry is active on all pedals. With the H9’s bypass mode set to DSP or DSP+FX, I seem to be loosing volume in my signal. With it set to Relay, I get the volume back but my delays and reverbs from the Strymon pedals are almost lost. Am I doing something wrong here?
