Introduced in the early 1970s, the Omnipressor® was the first dynamics effects processor of any kind. Invented by Eventide's founder, Richard Factor, the Omnipresssor, made a host of effects possible. It featured variable control of all aspects of dynamic modification. It also introduced the notion of the 'side chain' and foretold techniques that today we take for granted like 'look ahead' processing.

Factor's original design, the "white-face" Omnipressor 'featured' controls that made the unit virtually impossible to use. In fact, here's the opening paragraph of the original user's manual:

"...if you don't fondle it's controls properly it will cause you hours of confusion and tempt you to dash it against the rocks or put it in a sack and drown it."

Engineer Jon Paul was brought on board to tame the beast and the "black-face" Omnipressor was born. It has been used on hundreds of hit records throughout the last four decades and many of the original units are still in service and cherished.

The Omnipressor plug-in is a faithful emulation of the "black-face" unit and is popular among some of the world's leading producers and engineers as a dynamics-modifier with variable expressive controls of all aspects of a signal's dynamics.

The Function control allows you to set compression and expansion ratios over a wide, continuous range from extreme expansion to infinite compression and beyond - dynamic reversal which reverses a sound’s envelope, making loud sounds quiet and quiet sounds loud.

One of Eventide's first customers was a young Brian May, lead guitarist of Queen. With the Omnipressor in his rig, his sound was never the same again.

  • Dynamics processing for creating otherworldly sounds
  • Variable control of attack and release time
  • Variable control of maximum gain and maximum attenuation
  • Function control sets ratio over a continuous range from extreme expansion to infinite compression and beyond to dynamic reversal
  • Gating: Set a threshold and signals whose amplitudes fall below the threshold value are 'squooshed'
  • Expansion: Widen a signal's dynamic range. Loud gets louder, soft gets softer
  • Compression: Variable control of compression ratio
  • Infinite compression: Obliterates a signal's dynamics - everything comes out at the same level
  • Limiting: Versatile, fast limiter
  • Dynamic Reversal: First of its kind. Soft signals come out loud, loud signals come out soft. Simulates tape reversal
  • Intuitive interface makes it simple to operate with the use of a function dial
  • Dozens of presets to help you explore the unique and inspirational sounds of the tool used on countless hit records

Some of the unusual capabilities of the unit are illustrated in the graph below.

Press Quotes

"Omnipressor is a compressor and expander/gate dynamics plug-in that goes about the business of compression in a very aggressive and shouty way. If you are looking for a subtle transparent compression then look somewhere else, if you want a compressor with bags of pump, depth and character then look no further." - Pro Tools Expert

"[Omnipressor] is the most twisted, aggressive, nasty, and yes, seductively versatile dynamics control device I've used...The Bass Cut switch is way cool for kick drum fans, as it attenuates bass frequencies going to the compression control circuit." - Harmony Central 

"I thought it would be interesting to compare the plug-ins to the hardware they emulate. To be honest, I was not expecting them to be that close in sound, but I was in for a surprise...I was kind of blown away at how alike they sounded after trying several different settings on each processor." - Tape Op
