I know you do not want midi, but it sure works great. I setup a separate track in RB, and route it thru channel 13 and have starts stops, and scale, or chord setting, pick the harmonies, i want between 1 to 4, and much more. I use a TC helicon voice works, and love it. Sometimes i actually sing the harmonies into it and record the tracks, and then i can really tailor them to the song, and not have a glitch live.

When you sing the melody and allow the unit to harmonize it sounds great, but i like sometimes to sing the harmony and use a 3rd off that or a fifth and i get some nice stuff. You can sing one, let the box do another, and then keep layering with this unit. It also has effects, thickening, and pitch correction.

Why i really like the rack unit is that i do not want to have to remember when to click the floor button, it just adds another chance to forget to either turn it on or off, and another layer of difficulty to the song. It is so sweet when it turns itself on and off, and i just play and sing. Much more work that the other way in the beginning, but far less work afterwards.

I set it all up in the event list for that track and it is nice.

Slowly i want to build recorded tracks
