TriVox: Harmonizer Effect Plugin by W. A. Production Free Download

Each of the three harmony voices can be pitched across a range of 12 semitones down and 12 semitones up. Individual level controls let you balance the voices against each other and against the original signal.

Scale locking keeps the harmonies in key. You can choose from 20 scales, or switch to chromatic mode when you want intervals that ignore the key. A Randomizer generates unexpected combinations of voices and settings, which is useful when you want ideas you would not reach by hand.

The Super Unison knob, with its Detune and Spread controls, thickens the harmonies and widens them across the stereo field. The Character slider moves the voices between organic and synthesized tones, so you can shape the texture to suit the track.

Dry, Wet and Output Gain controls make it easy to blend the processed signal with the original. A Global Limiter toggle helps keep the output level under control. The plugin includes factory presets as starting points, plus a PDF manual and tutorial video.
