There are some differences in the Tag fields available in MC 12 vs. 11.
In the tag info, I can't seem to find the Last Played field. I can see how many days ago it played but then I'd have to pull out a program to calculate what date that was.
While in the Tag info, it has been mentioned that the BPM field isn't there but the Intensity field isn't either. Both BPM and Intensity can be edited in MC 11.
In the detailed Format info, it displays COMM (Date) as a number like 28126. This doesn't appear to be a Julian date. What is it?
