When I plug into input H and record, it will not play back through track 8. meters show content, assign is correct, line/guitar switch on line. but when I turn up 5,6, and 7, I can hear it. if I assign input h to any other tracks, it works. If I record H on track 8 and then clone it to another track, it works. Am I missing some small detail? also after firmware update 1.04, Im getting file error messages. Ugh I love this unit, had it for about a year and a half and now that I'm actually using it productively its messing with my mojo. Any suggestions?
