Vocal Algorithms
The H90 goes far beyond a standard effects pedal, now expanding its capabilities with four new studio-grade vocal algorithms: VocalTune, VocalShift, VocalShiftMIDI, and Quadravox+.
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!
Creative Soundscapes
Transport your audience to new sonic destinations. By seamlessly blending any two algorithms you wish, the H90 excels at crafting immersive soundscapes and otherworldly textures.
Synth Programs
Push the boundaries of sound design. These sophisticated programs will transform any input into a rich electronic ensemble. From vintage analogy warmth to crystalline digital textures, the H90 realizes your most ambitious sonic visions.


Live Performance Machine
The H90 Harmonizer is a live performance powerhouse! 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.
Adjust expression mappings by hand with the PERFORM HotKnob and engage up to six individual assignable parameters with the three push-button Quick Knobs.
Comprehensive UI
The comprehensive UI allows you to control any parameter with ease. 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.
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.



Dual FX Processing
The H90 Harmonizer’s dual algorithm design features true spillover between programs, series or parallel effect routing, and flexible I/O.
- Two Mono Inserts
- Dual Mode
Two Mono Inserts allow you to incorporate outboard effects in any configuration or combine them for one stereo insert. Optimize your signal flow with instrument or line level operation and full gain controls.

Dual Mode allows you to connect using the four-cable method or process two independent stereo instruments at once! Let the H90 Harmonizer take you beyond the effects horizon.


H90 Control
H90 Control is an easy-to-use remote app for programming your H90. Manage Programs and Presets, perform system updates, program MIDI mappings, and import/export User Lists. Connect via Bluetooth or USB-C using your computer or iPad.
Register your H90 pedal to your User Account to download H90 Control for Mac or Windows.
