So, I've got several finished songs in Logic 9.1. How can I import the individual tracks into Mainstage2? I've tried a lot of tactics except for what works apparently. Not much info on MS2 out there.
You can import audio files bounced from Logic directly into a Mainstage 2's Playback plugin.
Insert the Playback plugin in Instrument slot on a software instrument.
Drag the audio file onto that channel strip or from Playback plugins interface click on the gear icon : import audio file
