Hi, I was recently doing a mix down on to a CD recorder and followed the basic steps on the 840 to be able to do that. But then when I slected the Pan option, it would not pan what I had recorded on tracks 1, 2, 3 and 4. Everything was just straight up...Now Ive been using the unit for years and never had an issue with it not letting me adjust each track where you can hear it go from left to right while using the Time/Value dial through the headphones. And I dont remember doing anything different from before. Does anyone have any thoughts as to why those tracks wouldnt pan? Thanks
