No, it is NOT the same as shipped in BB. The Harmony M is a hardware pedal used to create harmonies via midi notes froma keyboard. The TC in BB/PT is a software harmony generator, made by the same company, TC Helicon.

The TC Helicon in BB/PT will work "ok" if you you use a clean, dry, and in-tune mono vocal for it to use to create harmonies with. My choice is to use "follow the chord changes" setting in the TC box. I also set them to send each harmony created to its own track in PT.

The cleaner the original mono vocal track is, the less "robotic" sounding tracks it creates.

You can then add FX, pan and create a mix to blend them to sound more natural.
