The Eventide H9 Harmonizer Gen 2 is a compact multi-effects pedal that combines the complete H9 Max and H90 algorithm libraries, modern ARM processing, stereo I/O, MIDI connectivity, Bluetooth control, USB-C integration, seamless preset spillover, advanced polyphonic pitch-shifting, and over 1,000 presets in a powerful studio and live performance platform. The Next Generation of Harmonizer The H9 Harmonizer Gen 2 builds on the success of the original H9 series while introducing the complete algorithm collection found in the H90. It includes all 52 H9 Max algorithms alongside the expanded H90 effects library, delivering a total of 74 algorithms covering delay, reverb, pitch shifting, modulation, granular processing, vocal effects, looping, synthesis and sound design. Eventide has designed the platform for long-term growth, including full compatibility with legacy H9 presets while supporting future algorithm updates through its modern software architecture. Users can migrate existing sounds without rebuilding presets, while gaining access to a significantly expanded processing environment. Advanced Processing and Sound Quality The H9 Harmonizer Gen 2 utilises the same modern ARM-based processing platform found in Eventide's flagship H90 and H9000 processors. This architecture delivers higher fidelity audio performance, increased processing power and smoother operation across all algorithms. Eventide's proprietary Spectral Instantaneous Frequency Tracking (SIFT) technology enables highly accurate polyphonic pitch shifting. This technology powers advanced algorithms including Polyphony, Polysynth, Polyflex and Prism Shift, allowing complex chordal material to track naturally while maintaining excellent note separation and tonal integrity. The pedal also supports seamless effect spillover between preset changes, ensuring delays, reverbs and ambient textures continue naturally when switching sounds during performance. Redesigned User Interface Eventide has completely reworked the H9 user experience with a larger 2.5-inch display, three dedicated Quick Knobs and redesigned button controls. The updated interface provides direct access to parameters from the pedal itself, removing the need for app-based editing during setup or performance. The operating system centres around three dedicated workflow modes. Select Mode enables fast preset browsing, Bank Mode simplifies live set organisation and Perform Mode provides immediate access to real-time effect manipulation. Together, these modes create a more streamlined workflow for both studio and stage applications. Real-Time Performance Control The H9 Harmonizer Gen 2 introduces enhanced hands-on control through Eventide's HotKnob and HotSwitch functionality. Users can assign multiple parameters to macro controls, allowing dramatic sound transformations from a single gesture. Two programmable footswitches support flexible operation across different performance scenarios, while expression pedal and auxiliary controller compatibility provide additional real-time control options for demanding live environments. Connectivity for Modern Setups The H9 Harmonizer Gen 2 integrates easily into contemporary guitar, keyboard, vocal and studio systems. Stereo audio inputs and outputs support both instrument and line-level signals, making the unit suitable for pedalboards, effects loops, synthesisers and recording environments. USB-C connectivity enables integration with Eventide Control software, while Bluetooth support allows wireless editing from compatible Mac and iPad devices. Traditional 5-pin MIDI I/O ensures reliable communication with professional hardware rigs, controllers and automation systems. Flexible routing options, including Wet/Dry and Pre/Post configurations, provide extensive integration possibilities across complex signal chains. Vocal Processing Capabilities When paired with the Eventide MixingLink (sold separately), the H9 Harmonizer Gen 2 unlocks access to the Harmonizer+ vocal processing suite. This combination enables professional-grade vocal harmonies, pitch processing and vocal effects, extending the unit beyond traditional instrument processing applications. Built for Live and Studio Applications The H9 Harmonizer Gen 2 maintains the compact footprint that made the original H9 popular while significantly expanding its capabilities. The combination of advanced processing, comprehensive connectivity, expanded algorithm selection and intuitive control makes it equally suitable as a standalone effects processor, pedalboard centrepiece or studio production tool.
