Thanks for your answers. So, since I have created several songs with BIAB and I now have Mixcraft 9 with the plug-in. I load a song I've created in the BIAB already inside the plug-in, so you're saying here I can add new instruments within BIAB, that I will have more tracks than the 8 or 9 (can't remember) ordinarily I can use in stand alone BIAB? Then, I supposed I can drag and drop the master which will get lets say 12 tracks into my Mixcraft? Actually, had trouble with the drag and drop from the master, another problem.

What I did was do my song in BIAB? Add some additional instruments on the soloist track and maybe audio. Saved as SGU files. Went to Real Band opened the song export each track into a folder as .wav files. Then I went into Mixcraft and said load Sound file for each of the tracks to get them all over into Mixcraft. Probably is a short-cut but I couldn't figure it out.
