Quadravox

Eventide

Where to get itAvailable from Eventidestore.eventideaudio.com

Quadravox is a diatonic harmonizer plug-in that combines four voices of pitch-shifting and delay in a Notation Grid interface, allowing you to create simple harmonies or complex rhythmic sequences. It draws from Eventide's flagship processors (Orville and Eclipse) to deliver high-quality harmony effects with independent control over each voice's pitch, timing, level, and feedback. The Notation Grid provides a musical, grid-based approach to voice placement and manipulation, while extensive parameters support both key-based and fixed-pitch shifting modes.

Written from the manual and checked against it. How we check

Key Features

01Four voices of diatonic pitch-shifting and delay
02Notation Grid for visual voice placement and quantized intervals
03Voice-independent feedback loops (post-pitch-shifter)
04Diatonic pitch intervals up to 2 octaves with key and scale control
05Pitch Cents for fixed pitch shifts, micropitch, and detuning
06Integrated stereo mixer with per-voice pan and level (0 to –100 dBfs)
07Up to 32 Snapshots with Global and Current banks
08Tempo-based delay calculation with key-lock and mix-lock features

Things to Try

  • 01Use Voice Select to bring forward stacked voices with similar delay times before editing in the Notation Grid
  • 02Hold Command key while dragging voices in the Notation Grid to move freely without quantization to 16th-note subdivisions
  • 03Enable Pitch Tracking off when processing non-pitched or polyphonic sources like drums to treat all input as the scale root note
  • 04Set cumulative voice Delay Feedback below 100% across all four voices to avoid run-away feedback and audio muting
