Highlight each track and use
'Track - export track to file'

This will give you a wav file of each track that Logic should be able to import.
*Note that if you want to incorporate any active effects into the tracks, you'll have to do it differently.
Activate solo button, and then use 'Audio - merge tracks to stereo wav file'
You'll have to highlite each track and do this procedure to get the effects incorporated.

I do not work here, but the benefits are still awesome
