I got the tascam dp-o1, it's my first time trying to record...I am having a great time with it...but I can only figure out how to record up to two tracks...For some reason, if I try to record the third track, nothing happens. I can hear myself singing/playing in the headphones, and the meters are going, but still nothing records. I tried using the input A and B, I tried using other track numbers besides # 3, the volume is turned up on the tracks and the mic...does anyone have any experience with this machine? It is supposed to record up to 8 tracks, and I have searched the manual but can't find anything regarding this problem. Any help would be much appreciated, thanks alot.
