When I look at the main LED window you know I can see my FX chain (overdrive, noise gate, amp, mixer...). All of those follow each other with no empty spaces in between. But I got something at the far right end that I don't know for sure what it is. It says things like Playback and Overdub, so what would that be? I tried to move it so it would be right next to my delay but I can't move it there. It only wants to move at the far left which is the beginning of the FX chain.

I don't get it.
