^^ I know I am a broken record about this deck and it seems I can't convince the converted, but I hope that before recommending it to anyone, the converted pay attention to the number, type and variety of threads like this about it. The 680 has an amazing feature set for the price; I wish I could say the same of Tascam's quality control and software.
Steve, I hope this works out for you and sorry that you are having issues.
