What is Elastique Pitch?

If you haven't come across Elastique Pitch it offers independent control of pitch and timbre (often called formant shifting). It supports up to 8 channels so you can process up to 7.1 audio and is phase coherent across the channels. You can control it via MIDI and there are presets for some of the typical film and TV pull up and pull down conversions.
