Is anyone still working on this program? If so let me know. I've taken a look a the the code and think I have a few things to help out.
For example, change the line where modemacro is set in the MP3 basic module to the two lines below to only show the filename, not the full path:
FileName = Mid(FileName, InStrRev(FileName, "\") + 1, Len(FileName) - InStrRev(FileName, "\") - 4)
ThisDrawing.SetVariable "ModeMacro", "CADAmp: " & FileName
If nobody else is working on it, I would be happy to add in playlist and multi-play functionality.
