Eventide H90 Harmonizer Multi-Effects Pedal - White

Built to serve as the centerpiece of a modern pedalboard, the Eventide H90 Harmonizer is a flagship multi-effects pedal that combines studio-grade processing with performance-ready control. At its core are 74 professional algorithms spanning reverb, delay, modulation, pitch shifting and advanced sound design, giving players access to the signature Eventide effects heard on countless recordings. The H90’s dual-algorithm architecture allows two effects to run simultaneously within a single Program, enabling layered textures, complex signal chains and creative combinations that would typically require multiple pedals. Hundreds of curated factory Programs provide instant access to polished sounds, while flexible routing, MIDI integration and an intuitive front-panel interface make the pedal equally at home on stage or in the studio. Whether building expansive ambient soundscapes, crafting precision pitch harmonies or shaping detailed modulation chains, the H90 delivers the flexibility and sonic depth that have defined Eventide’s Harmonizer legacy. 74 Algorithms and Dual-Effect Processing The H90 provides an extensive collection of 74 algorithms that cover the full spectrum of professional effects processing. Classic delays, lush reverbs, modulation textures and Eventide’s renowned pitch-based effects sit alongside new processors designed for modern sound design and experimental processing. Each Program can run two algorithms simultaneously, allowing players to combine effects in series or parallel for sophisticated signal chains. This architecture makes it easy to pair harmonized pitch shifting with delay, layer modulation with ambient reverb or construct multi-stage effects that remain clear and controlled within a single pedal. Exclusive algorithms such as PolyFlex, Polyphony and Prism Shift expand the pedal’s capabilities further with advanced polyphonic pitch processing powered by Eventide’s SIFT tracking technology for fast, accurate and natural pitch response. Vocal Harmonizer and Synth-Based Programs Borrowing technology from Eventide’s flagship H9000 processor, the H90 also introduces the Harmonizer+ vocal algorithm suite for shaping and transforming vocals live or in the studio. Algorithms including VocalTune, VocalShift, VocalShiftMIDI and Quadravox+ provide tools for pitch correction, harmonization and MIDI-controlled vocal processing. In addition to vocal processing, the pedal’s synth-focused programs—such as PolySynth and other pitch-driven algorithms—can transform a standard instrument signal into layered electronic textures ranging from analog-style warmth to crystalline digital tones. These tools expand the H90 well beyond traditional guitar effects, opening creative possibilities for producers, sound designers and performers working across multiple instruments. Granular Algorithms and Expansive Sound Design Eventide continues to expand the H90 platform with four granular-based algorithms available as a free firmware update. Cosmic Web blends reverse-pitched grains with Eventide-style reverb to generate deep, evolving delay textures and spacious pad-like ambience. Glitch slices and reconstructs audio using multiple glitch engines capable of aliasing artifacts, granular burst patterns and pitch-shifted sample-rate effects. GrainMod introduces three independent LFOs that modulate grain parameters such as trigger rate, duration and filtering, allowing textures to evolve continuously rather than repeat. Completing the set, Stutter creates rhythmic burst patterns ranging from tight rolls to scattered glitch textures with probability-based triggering and footswitch control. Together these processors push the H90 Harmonizer beyond traditional multi-effects processing into a powerful environment for immersive soundscapes and experimental audio manipulation
