Being an old coot from a bygone era, I must admit that much of this digital stuff simply confuses the hell outta me. I'm barely able to function within the Audacity system, which has been said to be primitive compared to many others out there. No doubt true, and being brutally honest (just ask my ex-wives when they asked "Does this dress make me look fat?") I often still record on tape creating many tracks and load them into the computer for final mixing and storage. I understand tape well.... But back to Miss Heket's issue with the USB from her little amp going into the computer and not getting both the wet and dry signal. I take it that the USB signal is from the preamp, and this USB connection also serves as the prime manner in setting up the programed files in it's own little internal digital stuff and to add downloads for updates and such? Quite a lot for one little device. But I'm still wondering how, if its sending a stereo signal to the computer, it fails to get both sides of this as an input to the stereo input to Audacity's program? Thinking along the lines of an old tape guy I have now answer. But trying my best in digital thinking I can only assume that there is something in the setting of the input for the program that's causing a mono type signal to enter. Perhaps the selector for the input is in fact set on mono rather than stereo, and thus is choking the signal and compressing it? I'm just taking a stab at this with my analog brain and may well be all wrong too. I'm sure there is a logical solution to this issue that awaits discovery. We just haven't found it yet.
