TBH I find this method (below) usually works out quicker and safer for the final audio and placement. Especially if multiple tracks are involved......

Save the song in BIAB, then open it in Realband, then go to AUDIO - Save All Tracks to Individual Files WAV MIDI

This creates a new folder with all the audio ready to do with it as you please. I then open Sonar and use the import audio function.

The bonus of this method for me anyway, is that if I do happen to stuff up an audio track in Sonar, the original is always there to re-import without the need to fire up BIAB again.

Just a suggestion smile
