Eventide DSP4000 Ultra Harmonizer

Eventide DSP4000 Ultra-Harmonizer®

The Eventide 4000 Series Ultra-Harmonizers are multipurpose programmable digital audio signal processor with pitch change capability.  It is the latest and greatest in a line of pitch change special effects units stretching back to before most audio manufacturers ever heard of digital.


We call the Eventide DSP4000 Ultra because it does more than our earlier models. And it’s a lot more. The 4000s are capable of creating effects you’ve never heard before (and neither has anybody else).

It has a built in patch editor to let you create your own effects algorithms. The 4000s are fully MIDI addressable, with click less, realtime MIDI control.

The different ®Harmonizers in the 4000 series are tailored for specific marketplaces and include features optimized for that marketplace. Most of the features of each model are available as options for the other models.

Options include different factory presets (available on memory cards from your dealer), audio sampling, S/PDIF and AES/EBU digital audio inputs and outputs, and software upgrades. Each Harmonizer comes equipped with hundreds of factory presets (programs).



Quantization: 16 Bit
Sampling Frequency: 44.1
Frequency Response: 5Hz-20kHz
Dynamic Range: 92dB
THD: Below 0.01%

This thing is fantastic. The H3000 gets all the hype but any of the Eventide Ultra-Harmonizers sound stellar.

Doesn’t have the mojo as the H3000. However the Reverb with doubler is excellent on horns. Many veterans will tell you the H3000 is the one to get but this piece seems to sit in the mix just right.
