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

The H90 Harmonizer comes with hundreds of factory Programs that can be loaded using either SELECT or BANK mode. In SELECT mode, you can navigate your Playlist sequentially without ever missing a detail thanks to the OLED display. In BANK mode, you can quickly load from a bank of three Programs, perfect for cueing up the range of sounds for a song. Organizing your favorite sounds has never been easier, simply load a new Playlist and you’re ready for the next gig! 

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.

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.

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 to incorporate the H90 into your rig or make it the centerpiece.

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