Curious to know why, being digital, I can't bounce up to eight tracks to two stereo tracks -- once, twice, or even three times -- without noticeable sonic degradation? I thought that was the whole idea of recording digitally? Along these same lines, more than once I've read the suggestion that it's preferable to export the individual tracks and mix them down externally on a computer to avoid degradation. What's the difference? Bit rate? Something else? I'm not far enough along to test this for myself but it seems, in principle, to be a warning carried over from the portastudio cassette days and not relevant to the current generation of products. Am I wrong?
