Eventide Octavox Plug-in



Instant Inspiration

Level up your composition skills with unique time-based diatonic harmonizer technology. Octavox is an inspiring tool that takes any incoming tones, even drums, and outputs up to eight voices based on the chosen key and timing interval. Based on technology from our flagship H8000 hardware effects processor, Octavox will take your melodies and ideas to new heights. Stack harmonies, widen instruments, and create innovative rhythmic sequences. Whether you are an electronic musician, singer/songwriter, or guitarist, Octavox has got you covered with more than 70 presets to boost your creativity with unheard melodies and rhythms.


Taming the Octopus

Octavox controls have been designed in the most intuitive way, allowing you to quickly adjust parameters or type in values. Each of the eight voices can be independently manipulated by level, panning, delay time with feedback, and pitch, including the type of musical interval. The effect can even be sync’d to your DAW tempo for killer, melodic, rhythmic delays. Octavox has also been updated with expanded MIDI functionality. Each voice interval can be set via MIDI note, voice shift amount by MIDI Pitch Bend, and “Randomize” by MIDI Modulation Wheel.


This plug-in is part of the Anthology X Bundle



Is it Live?

Octavox has always allowed you set harmony intervals and reproduce voices in the key and scale you're singing in.  However, new MIDI functionality allows you to change these intervals on the fly allowing you to add moving harmonies to your performance or recording.

8 Voices

8-voice diatonic pitch shifter based on technology from Eventide’s flagship H8000 effects processor with panning, delay, detune, and feedback to create beautiful harmonies and sequences.

Randomize function randomizes an amount of micro pitch shift resulting in simulation of natural character for each of the 8 voices.

70+ Presets

Whether you are an electronic musician, singer / songwriter, or guitarist, Octavox has got you covered with more than 70 presets to boost your creativity with unheard melodies and rhythms. Great on monophonic synths, guitar, and vocals.

Diatonic Pitch Shifter

New pitch-tracking ‘off’ mode allows it to shine on polyphonic and rhythmic sounds. MixLock keeps the wet/dry mix of the effect static as you scroll through presets or user-defined snapshots. Key Lock does the same for the Key and Scale.


Select key and scale

Unique Notation Grid presents pitches on a traditional music staff with a quantized grid for placing notes over time allowing for a more musical programming experience. Color and brightness indicate pan and level for each voice.
