The EHX Intelligent Harmony Machine instantly creates harmonies tailored to what you're playing. It’s like having one – or even two – guitarists jamming with you at the same time and always in perfect sync. The Intelligent Harmony Machine opens the door to large, multi-lead guitar group music and multi-voice harmonized solos. Plus, its ability to apply harmonies ranging from simple to sophisticated will totally transform what you play. Of course, it also benefits from EHX's renowned impeccable tracking and authentic musical sound.

Select your key and the Intelligent Harmony Machines will generate single-note diatonic harmonies* with a wide range of choices including two- and three-part harmonies. Here are your choices:

1 6th down

2 perfect 4th down

3 3rd down

4 3rd up

5 perfect 4th place

6 Perfect 5th Up

7 6th more

8 7th highest

9 3rd plus + 7th plus

10 3rd plus + 7th plus

11 Perfect 5th Up + Octave Up

These look so cool that we've included them as additional options for the multi-harmony parts (selections 9, 10 and 11) to give you even more choices:

9 optional 4th bottom + 3rd top

10 3rd upper + 6th upper optional

11 octave down optional + 5th up

9 6th bottom + 4th bottom optional

10 3rd bottom + 3rd top optional

11 octaves down optional + 4th down

The Intelligent Harmony Machine also performs perfect polyphonic pitch changes so that the pitch changes you compose are applied to chords as well as single notes. We've even included a Major/Minor switch so you can choose whether the 2nds and 3rds will be major or minor. Here are the interval selections available:

1 Voice actor

2 perfect 4th down

3 3rd Down (minor over major)

4 3rd higher (minor or major)

5 perfect 4th place

6 Perfect 5th Up

7 2nd Down (minor or major)

8 2nd higher (minor or major)

9 octave down

10 octaves up

11 Perfect 5th Up + Octave Up

The Intelligent Harmony Machine's Moment mode lets you instantly change pitch with just a press of the pedal's footswitch. Pitch shift is engaged as long as you hold F/S. There is also an option allowing you to apply a user-defined swipe time between drying and effect. Choose instant pitch changes or control how long it takes the Intelligent Harmony Machine to sweep up and down between the set interval and the sharp signal!

EHX founder Mike Matthews said: “We designed the Intelligent Harmony Machine for the gamer who wants maximum power, but with a minimal footprint. You will appreciate its soft and musical sound and its impeccable tracking! »

* Diatonic harmony means notes in a specific key that relate to each other.

Compact harmony generator, pitch change central

Impeccable tracking and superb musical sound

Two distinct modes: Intelligent Harmony and Polyphonic.

Smart Harmony Mode generates diatonic harmonies in a defined key based on the individual notes you play. The key selector and #/- switches provide access to all 12 keys.

In Polyphonic Override mode, you can play single notes and chords. The HMI's 11-position interval selector allows you to select harmony.

In momentary mode, the effect is only active when the footswitch is pressed. Choose from instantaneous offsets or set the time it takes for the signal to sweep up and down.

The mix control sets the mix between your dry and offset signals. Dry output adds signal routing and control options and flexibility

Comes equipped with a 9 volt EHX power supply, can also run on 9 volt battery
