I have Realband and BIAB 2010 and have seen alot about TC Helicon. Its my understanding the only way to use it in Realband is to have Power Tracks installed as well? I use Realband most of the time. My question is this.......
Is it possible in any of these to import a vocal track made in say Sonar, and create harmonies using TC Helicon or does the track have to be recorded "inside" one of the programs?

Thanks in advance for any help.
