The Electro-Harmonix Intelligent Harmony Machine is an effects pedal that combines a pitch shifter...The Electro-Harmonix Intelligent Harmony Machine is an effects pedal that combines a pitch shifter, harmoniser, and polyphonic de-tuner. It's designed for solo musicians or bands needing to create multi-guitar sounds and symphonic leads. The pedal features a 'Poly Override' mode with ten settings for polyphonic pitch shifts, allowing you to play single notes and receive rich harmonies in the correct key. It can generate single-note, diatonic harmonies, including two- and three-part harmonies, and also performs polyphonic pitch shifts with a Major/Minor switch. Users can set the sweep time between dry and effect signals for instant changes or controlled transitions. The Intelligent Harmony Machine boasts impeccable tone and offers two distinct modes: Polyphonic and Intelligent Mode. In Polyphonic Override, you can play chords, while Intelligent Mode generates harmonies based on the notes you play. It includes a mix control for shifted signals and comes with an EHX 9V power supply, with the option to run on a battery (not included).
This guide is for musicians looking to expand their sonic palette with rich harmonies and pitch-shifted effects. The Electro-Harmonix Intelligent Harmony Machine (IHM) offers a versatile solution for creating complex vocal and instrumental arrangements, whether you're performing live or recording in the studio. While it excels at generating harmonies, users should be mindful of the learning curve associated with mastering its various modes and settings. The IHM combines pitch shifting, harmonization, and detuning capabilities, offering both polyphonic and intelligent modes for diverse tonal options.
