I use VoiceLive 2 when I stream using BIAB 2017 live. I have no issues but it took me months to work out how to integrate it. I use midi commands from BIAB on the soloist track. I have a VoiceLive 3 Extreme, but I've yet to get round to setting it up. It takes a lot of fiddling to get a harmonizer to sound real - if it ever does. Having said that, I love what it does for me. Also, they are so much more than just a harmonizer. It is my vocal sound engineer, de essing, compressing (all intelligently) Autotune, delay, reverb, doubling, fx effects etc, choirs, harmony, acoustic guitar effects and that's the VoiceLive 2. The voiceLive 3 Extreme is a whole different ball game, automated effects on your vocals, guitar whilst playing your wave file backing tracks inside it and and recording your show. Imagine you, your mic, guitar/keyboard and Voicelive 3 straight into a PA. No need for BIAB, a computer or anything else. Looping and electric guitar multi effects also with automation. These are big beasts with incredible power, but if you think BIAB is a steep learning curve...... grin
