T C helicon

jcdjms, I own the TC Helicon "Voice One", as well as the, "Voice Works". Depending on what you need to accomplish, both of these (hardware processors) are excellent for Harmony as well as that, "Cher Affect" (effect!) that everyone was looking for... I'm not familiar with the software based Program by TC but I do own Melodyne Studio & that is a Super Program but as you note, you have to do some dragging around & a bunch of other tweeks whereas the Hardware Processor has several presets that have a great Double, or you can add an Octave up &/or Down, or "Minor 3rd, 5th, or 7th" or all of them together... You can also add Breath, Growl, ect.... Let me know if your in the market for a great processor! HTH,,, NCWildman
