Hi,
So sad to see this, but it tells you that some folks are living off old technology and they simply do not have programmers capable of dealing with drivers ... years ago, they didn't need drivers, they just plugged things, and that is the time and place that Tascam came from.
Why would we be surprised? The other company with the worst tech support is IK and it's set of bad stuff, and no one in their company knows computers!
