Merging Pyramix 4.3 User Manual page 157

Shows the track number within the media file. I.e. a stereo file will have A1 and A2 for the two tracks.
File Name
Shows the full media filename including the unique identifier and extension.
Note: The values shown in the Clip, Media and Media Track sections reflect the track
clicked on in the Timeline. Where a selection contains several, possibly multi-channel,
clips, clicking on the individual items in the Timeline updates the information to reflect
the last item clicked.
The Selection Tab Window is automatically updated when the selection changes and can therefore
remain floating.
