A friend of mine recently tried to, due to a lack of tracks live, use three different devices (a Tascam 246 4 track, a JVC TD-W318 consumer casette deck and a computer) to record 6 tracks of audio. The Tascam and the computer's audio lines up perfectly, however, neither lines up with the JVC. It seems to be off by roughly .35/second. As long as they are recorded and played back on the same devices (no pitch controls engaged) shouldn't they line up? Anyone have any idea why this isnt working?
