Enhance your composition skills with Octavox’s unique time-based diatonic Harmonizer® technology.

Whether you’re stacking harmonies, widening instruments, or crafting innovative rhythmic sequences, Octavox is an inspiring tool for electronic musicians, singer/songwriters, and guitarists. With over 70 presets, Octavox boosts your creativity and productivity.

8 Voices

8-Voice diatonic pitch shifter based on technology from Eventide’s Harmonizer® effects processors 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-of 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.
