I am currently in production meetings for a show I am sound designing/engineering this Spring and the director and musical director have asked me if it would be possible to use Autotune live to help out two of the secondary principles who are sometimes having trouble staying completely on pitch. Personally, I think this is ridiculous but that is sort of besides the point. I think I can do this by routing an insert on their body mic channels (Countryman B3 via Sennheiser 500g2) into a computer running Autotune under a VST host program and then back in to the mixer (DM1000v2) but does anyone know if it will be able to do a decent job live? I haven't ever used Autotune before but I recall seeing in a presentation on it that you need to give it the key for each song to get good results. I would imagine that I could automate this via MIDI from the DM1000 to be recalled in conjunction with each scene but I could be off on this. Anyway, my basic questions are: 1) Will it sound alright? 2) Are there technical hurdles that I haven't thought of that I should be prepared for? and 3) Has anyone ever done this and, if so, do you have any advice/thoughts?
