The search while playing feature works great Dave. I was just going to tell you how to do it but AJ already explained. One thing AJ mentioned is that the mic inputs can also be line in's in stereo, but not if you are also using a mic. Then, it would only be a mono in for the line. I too wish there was a dedicated octave up and down rather than having to simultaneously push two buttons and having to toggle up normal and down..
