Good points that Rharv is making. You need to have a specific track go to the TC unit...each time...other wise its a nightmare telling the TC unit which track to listen to. If you are using midi, the TC unit "listens" to the track that you send it and generates harmonies from that. It is usually best to use a track heavy with chords...rhythm guitar or piano...for the track that is sent to the TC unit. Although sometimes, you may just have to use a melody track if that's all that you have.

Be sure to setup your DAW such that its sending your desired track on the same midi channel that the TC unit is listen on.
