reTune is zplane’s real-time polyphonic pitch-shifting plugin. You can use it to tighten up the tuning in an out-of-tune performance or change the key of a complete song. In this video review, Production Expert’s Eli Krantzberg tries all kinds of pitch shifting magic.

reTune can analyze the key of your song and then change it. From subtle variations to “let’s try this whole song in Major” alterations. You can even map note-for-note how you want to transpose your music. The advanced options include pitch sensitivity, transient conservation, pitch smoothing and a dry/wet control that can be used to create some interesting chorus effects.

reTune can be used in any number of ways, for instance:

  • Shaping up the pitch of a single performance to make it work better with the rest of the song
  • Changing the key of a complete backing track so it’s better suited for a vocalist’s range
  • Changing the key of a sample or loop to make it work with your song
  • crazy experiments: your favorite song but every note is G#

So, whether you are looking for a precise tool to glue a performance together or a creative-havoc effect to propel your project in a new direction, give reTune a try.
