Electro Harmonix Intelligent Harmony Machine Pedal Features
Two distinct modes: Intelligent Harmony and Polyphonic.
Intelligent Harmony Mode generates diatonic harmonies in a set key based on the single notes you play. Key Selector and #/- switches provide access to all 12 keys.
In Polyphonic Override Mode you can play single notes and chords. The IHM’s 11-position Interval Selector switch lets you select the harmony.
In Momentary Mode the effect is only active when the footswitch is depressed. Choose from instant shifts or set the time it takes the signal to sweep up and down.
Mix control sets the mix between your dry and shifted signals. Dry output adds signal routing and control options and flexibility
Comes equipped with an EHX 9 Volt power supply, can also run on 9 Volt battery
The Intelligent Harmony Machine’s Moment Mode lets you instantly change pitch by simply depressing the pedal’s footswitch. The pitch shift is engaged as long as you hold down the F/S. There’s also an option so you can apply a user-set sweep time between dry and effect. Choose instant pitch changes or control the time it takes for the Intelligent Harmony Machine to sweep up and down between the set interval and the dry signal!
