I am running Zortam MP3 Media Studio Pro 6.71 and when I have multiple files selected and choose ID3 Tagging > Copy ID3v1 To ID3v2 Tags the tags are not copied. I have to copy tags for each file individually.
I use MixMeister to determine the BPM (Beats Per Minute) of my files. MixMeister enters the BPM in the BPM tag. But Windows, Zortam and other programs do not display the BPM tag. So I use Tag&Rename to copy the BPM tag information to the Comment tag. But Tag&Rename corrupts my ID3v2 tags.
Please add display and editing of the BPM tag to Zortam, and if possible add BPM detection.
