Discover why top artists and producers have chosen Eventide for over 50 years with the H90 Harmonizer®, Eventide’s next-generation multi-effects pedal. Whether you want high-quality bread-and-butter effects or experimental sounds unheard, the H90 has everything you need to spark creativity. Designed with players in mind, it features an intuitive interface, 66 effect algorithms, and hundreds of curated Program combinations for a wide range of instruments and genres. With its comprehensive I/O and flexible routing options, the H90 is designed to be the heart of your rig.

New Effects, Endless Sounds

The H90 Harmonizer features modern ARM-based architecture derived from the world’s most powerful effects processor, Eventide’s flagship H9000 Harmonizer.

Exclusive Algorithms

The H90 not only offers the iconic reverbs, delays, modulation, and pitch-shifting effects of the H9 Max but goes far beyond with new powerful algorithms including state-of-the-art, fast-tracking, and warble-free Polyphonic Pitch Shifting.

Essential Programs

The H90 Harmonizer comes with hundreds of factory Programs that can be loaded using either SELECT or BANK mode. Organizing your favorite sounds has never been easier, simply load a new Playlist and you’re ready for the next gig!

Live Performance Machine

The H90 Harmonizer is a live performance powerhouse! The front panel has been reimagined with five push knobs, seven LED buttons, and a hi-res OLED display for greater hands-on control and parameter feedback. 

In PERFORM mode, you get six programmable footswitches. Map functions like tap tempo, preset and insert bypass with momentary states, and performance parameters like reverb freeze, pitch flex, or delay repeat. Furthermore, you can make multiple instantaneous parameter changes with three HotSwitches.

ComprehensiveUI

The comprehensive UI allows you to control any parameter with ease. Adjust expression mappings by hand with the PERFORM HotKnob and engage up to six individual assignable parameters with the three push-button Quick Knobs. Get even more control with two inputs for expression pedals or auxiliary switches with up to three buttons. If that’s not enough, take advantage of the pedal’s extensive MIDI control.

DualFXProcessing

The H90 Harmonizer’s dual algorithm design features true spillover between Programs, series or parallel effect routing, and flexible I/O.

H90Control

H90 Control provides remote control access and Program list management for the H90. Manage Program and Preset settings, perform system updates, and import/export User Lists with an easy-to-use interface.

Things Just Got Granular

Introducing four uniquely Eventide granular effects for the H9000 and H90 Harmonizer®. Blooming reverse delays. Rhythmic glitchy stutters. Skittering repeats that morph into unexpected textures. All new and available as a free firmware update.

Cosmic Web

High-end rack processing with a modern, macro granular package. Cosmic Web blends reverse pitched grains with classic Eventide reverb for deep delay and pad-like modulated space.

• Ping Pong mode bounces grains between left and right channels.
• A second independent delay mode modeled after the Crystals algorithm.
• Dynamic retriggering based on input threshold.
• Use Perform Mode to freeze the reverb, launch either voice into an infinite delay, or clear the memory of both.

Glitch

• Slice, distort, and reconstruct audio with three distinct glitch types. Each one works independently or stacks with the others for more complex results.
• Alias mode applies digital artifacts to the input signal, or to the output of another active glitch type.
• Burst mode groups short grains together with pitch shifting for a classic granular stutter effect.
• Clock Jumps re-pitch grains to different sample rates, while adding pitch warped effects via Clock Slew.
• Use Perform Mode to trigger glitches on command.

GrainMod

Morph your sound in novel ways thanks to modulated grain parameters. Three independent LFOs target Trigger Rate, Grain Duration, and Filter for textures that evolve rather than repeat.

• Each LFO features adjustable rate, depth, and waveform.
• Modulating Trigger Rate changes how frequently new grains are created.
• Control grain playback direction via square wave modulation with Direction Mod.
• Retrigger the Perform parameter for resetting all LFO cycles simultaneously.

Stutter

The classic granular effect. Create burst patterns with precise control over timing and subdivision. The effect ranges from tight rolls to loose, scattered patterns.

• Length and Rate parameters control burst duration and stutter spacing.
• Trigger stutters with probability-based chance mode, envelope sensitivity for dynamics-based triggering, or manually via footswitch.
• Smear softens stutter attacks while Spread fine-tunes stutter spacing.
• Perform Mode enables continuous stuttering, momentary triggering, or LFO reset.

Compatibility

H90 Harmonizer: All four granular algorithms are available as a free firmware update.
