1. Real-time multi-pitch modification - Now available! ReTune gives you full access to the pitch content of your audio samples and enables you to map each input pitch to any other pitch of the chromatic scale – all in realtime. This allows you to re-tune your audio to any target key (e.g. From D major to C# minor), or to use it as a creative tool to modify the pitch content in any way you like.
2. KeroVee can do the so-called ‘Autotune effect’ that is robotic but different from a vocoder. Visit for this and more free plugins.

Plugins for music and post. Industry leading pitch and time audio software including Elastique Pitch, ReTune and Vielklang. PPM tools for post production. Believe it or not, one of the best sounding pitch correction plugins (next to Melodyne,) is Reaper’s Reatune. While one can get a better overall experience in Melodyne, the amount of work is substantially lessened in Reatune. I would say Reaper’s plugin gets you 80% of the way that a thorough Melodyne edit will, in 10% of the time.
