Yes, I wanted to do this too. I have the Digitech Vocalist workstation. The only way I've found currently is to save them in a Band In A Box MIDI file and import that into Realband. It would be much simpler if we didn't have to go back and forth between the two programs.

Is it just my ears or does anyone else find the TC Helicon harmonies on the demo so awful-sounding that they would never want to use them?
