Thanks, I had run through the manual a few times last night in that section but had no luck. Tried again today and it seemed to click & I got it working. I think the problem was coming from having my ASSIGN buttons a bit confused as it doesn't really cover what to do with them in the manual for this section. I've never truely gotten my head around how they operate as it's never really come up with my recording as it just kinda works, but now I think I have a bit of homework to do to actually learn how they work.
Like, I dont know whats happening when L R is up vs down. Going to have a date with the manual tonight I think.
