Eventide Announces H9 Harmonizer Gen 2 - ARM-Based Redesign with Full H90 Algorithm Library
The H9 Harmonizer Gen 2 updates Eventide's single-processor multi-effects pedal with a modern ARM platform, the complete H90 algorithm library, and a redesigned interface that no longer requires a companion app for navigation.
Where the original H9 Max topped out at its own algorithm set, the Gen 2 opens access to 74+ algorithms drawn from both the H90 and H9 Max libraries, covering granular, harmonizer and vocal, delay, reverb, modulation, multi-FX, distortion, synth, looper, and utility categories. The over-1,000 preset count reflects that expanded range. Eventide states that new algorithms will continue to be added via updates.
The polyphonic pitch shifting side of the pedal runs on Eventide's SIFT technology, which powers four algorithms: Polysynth, Polyphony, Polyflex, and Prism Shift. SIFT (Spectral Instantaneous Frequency Tracking) is Eventide's approach to polyphonic detection and shifting without the pitch-correction artifacts that appear when standard monophonic algorithms encounter chords. Those four algorithms were previously exclusive to the H90, making their presence here one of the more concrete hardware-tier gains for H9 users considering an upgrade.
The granular category brings Cosmic Web, Glitch, GrainMod, and Stutter to the platform, the same set Eventide released as free updates for H90 owners in late 2025. Cosmic Web layers reverse-pitched grains against reverb; Glitch offers three distinct distort-and-reconstruct types that can stack; GrainMod runs three independent LFOs targeting Trigger Rate, Grain Duration, and Filter; and Stutter handles burst patterns with adjustable timing and subdivision.
On the hardware side, the Gen 2 adds a 2.5" display, button pads, and Quick Knobs, and organizes operation into Select, Bank, and Perform Modes. The intent is a pedal that can be navigated and programmed on the floor without the H9 Control app, which was effectively required on the original for anything beyond basic preset browsing. Connectivity includes USB-C, MIDI, aux switch, and expression pedal inputs. Bluetooth is listed as coming in a future update. The pedal handles both instrument and line-level I/O, includes effects spillover, and has a built-in tuner.
The Harmonizer+ Vocal Suite is also on board, though full functionality requires pairing with Eventide's Mixing Link interface, which is sold separately.
