The haters... I've heard haters hating on singers because of their use of technology. Not fair, really. Why should instrumentalists have all the fun.
The video above, part of some marketing fluff (but interesting and cool nonetheless) by tc electronic shows what's possible in real time with vocals. Holy crap. I knew about pitch correction but real time harmonization (playable!). Colour me impressed.
Hate all you want and when you're done accept that this is pretty cool.
Wonder what it would sound like on guitar?
