Octavox

The deal

$49 at KVR Marketplace (down from $99, 50% off). Deal runs through August 25, 2026.

What it is

Octavox is an 8-voice diatonic pitch shifter built on technology from Eventide's H8000 rack processor. It tracks pitch across polyphonic material and lets you independently set key, timing, pan, delay, detune, and feedback for each of its 8 voices, so you can build anything from tight vocal doubles to sprawling harmonic textures.

Who it's for

Vocal producers and mix engineers who want stacked harmonies without tracking every note by hand, plus guitarists, synth players, and sound designers looking for a pitch-shifting tool that goes well beyond a simple harmonizer.

Key features

• A Notation Grid lets you program pitch and rhythm visually on a musical staff instead of programming intervals blind
• Expanded MIDI functionality gives per-voice interval control for real-time performance
• Over 70 presets cover common harmony and effect starting points
• The MixLock function keeps your wet/dry balance steady while auditioning different presets
