In his reddit ama, Yung Gud is asked, "How do you guys do live autotune? Is there a separate software or is it just in the Antares autotune?" He responds, "TC Helicon Voicelive 2" The original reddit thread can be found [here](http://www.reddit.com/r/sadboys/comments/2vzp8p/im_yung_gud_and_i_can_answer_questions_now_if_u/combw2l).more
The manufacturer of the effects unit themselves (TC-Helicon) confirm Blake's use of the VoiceLive in their Facebook post, but the video link they use is broken. The unit can be seen throughout a performance on NPR Front Row (https://www.youtube.com/watch?v=j4qfT2dxU6E&t=884s), though—specifically in use for Lindesfarne at this timestamp.more
This unit is made by vocalists for vocalists, but actually becomes the ultimate live-gig processor for a mic'd saxophone, all in one convenient portable package. The VoiceLive series gives you the ultimate doubler and harmonizer, because it doesn't sound like an effect pedal ....it sounds more realistic! In my case, all the stock default settings had to be changed & tweaked for the sonic fidelity of a "saxophone" (not a vocalist), but it does everything extremely well, especially the harmony processing. For me, it gets used primarily for unison-doubling, unison-octaves, and 2 to 4-part harmony. The 2 biggest features on this device are: 1) HARMONY INTERVAL SETTING. I can "manually" set-up (initially program) harmonies into my presets quickly and easily using a keyboard connected to the Helicon's MIDI-In jack. OR ...I can elect to have the Helicon automatically set the intervals for me "in real-time while I'm playing" using (once again) a MIDI connection from the keyboard player's keyboard to the Helicon's MIDI-In jack, or from an analog-audio signal from the sound-mixer into the Helicon's audio-in jack. 2) Set-ups and/or harmony-intervals can be saved as SEQUENTIAL PRESETS and RECALLED ON THE FLY at any time during the song USING THE PEDALBOARD SWITCHES while you're playing. The VoiceLive 3 is probably a slightly better unit, but truthfully, the older VoiceLive 2 packs a punch and is truly amazing!
Only used it a couple times just because I haven't figured out my live set just yet, but it is an amazingly powerful vocal processor pedalboard and it has tons of presets and it is built to be very durable.
