Aside from the horrors of Auto-tune, the tool changed the state-of-the-art dealing with monophonic sound. Well, competitor product Melodyne will soon be able to apply pitch adjustment to polyphonic sound. This is huge. Huge. The amazing video shows this advance and a taste of the amazing power this will bring to recordists. About 2/3rds way through, it effortlessly changes the whole scale of a piece of music from minor to major, then to “Spanish”. It’s freaking amazing. [Thanks, shek-e]
