OK, so it imported on my Platinum and I can see and hear everything.
I unzipped everything and just opened the OMF file like it's an ordinary file. I didn't have to import in any special way.
It wanted to know tempo and sample rate in the beginning. I obviously guessed the wrong sample rate so for every file it said "converting sample rate".
I had to tell it to look in the subdirectory "Audio" once for the first file, then it found the remaining audio files on its own.
It created a directory "MixScenes", but it's empty. Is that a PT special thing?
There is also a file "msmFMID.pmr" which I don't think Sonar knows what to do with.
I am using Platinum, not Artist.
Anyone with Artist have a look to see if it has the option to save as OMF?
