I am recording on an old Tascam 424 (not mkII or mkIII) and i am having trouble bouncing tracks. i understand basically what to do, but i think i am missing a step that is lowering the quality of the final track. my specific situation is this: i recorded drums with two microphones, one for bass drum and one for overhead, and each mike was recorded to a separate track ( overhead is on track 3, bass drum is on track 4). i flipped the tracks from mic to tape mode to mix down the two tracks into one drum track so that i would have room for the other instruments. i planned on putting them into track one, so i panned both 3 and 4 hard left and set track 1 to the left position. the drums recorded to track one, but the volume and overall clarity of drums, particularly the symbals, is gone. when i listen to to tracks 3 and 4 in mixing mode, then mute them and listen to track 1 instead at the same volume, the quality is gone. to make a long story much shorter, i need to know the exact procedure for bouncing tracks together on an original portastudio 424. i want to know where every knob and switch has to be in order to correctly bounce the track. if anyone has a pdf of any form of the manual for the original portastudio 424 and can send it to me or tell me where to find it online, i would be beyond greatful. after much searching it seems as if it doesn't exist. thanks!!!
