The issue Jmschnur has reported is likely not related to the software upgrade. Rather, it is the way the software works. For example, I ran a Pro calibration over the weekend and recorded the recommended crossovers in a worksheet. To see if the calculation algorithm results in consistent recommendations, I loaded the saved measurements from the weekend calibration and let Pro run he calculations a second time.
As you can see in the attached file, the second set of recommendations do not match the first. Strangely, 40 Hz disappears completely from the second set of recommendations. Perhaps this is a bug, or perhaps the algorithm is so complex that it returns different results each time (which would be upsetting).
So, is it a bug and, if so, is it significant to warrant a case with Audyssey TS?
Edit: why can't I see the attached PDF on my iPad???
