Eventide H3500

Eventide H3500 DFX Sampling Ultra Harmonizer®

The Eventide H3500 is capable of creating effects you have never heard before (1992) and is fully MIDI controllable with click less, real-time MIDI control. The Eventide H3500 incorporates all the effects of the Eventide H3000-SE, plus the Mod Factory dynamic presets, and the Eventide HS322/395 Sampler card.


The Eventide H3500 came several years after the H3000 and added little more other than the sampling feature. Internal electronics remained the same as the Eventide H3000 so performance was ultimately the same.

Plug-In Options

Eventide H3000 Factory
The H3000 Factory combines the pitch, delay, modulation, and filtering that made the original H3000 Ultra-Harmonizer® a studio legend.
SoundToys Microshift
We designed MicroShift to nail the vibe of sought-after hardware pitch shifters like the Eventide H3000 (which featured algorithms originally designed by Soundtoys’ founders) and the AMS DMX 15-80s.
Eventide H3000 Band Delays
With the H3000 Band Delays you can play an effect like an instrument. Every parameter can be automated or manipulated in real time via MIDI. Play a filter with a keyboard controller to get not only rhythmic, but also musical results.
