Audio examples


  • Refreshed purple UI.
  • Sexier back panel design with a clearer layout for easier cabling.

  • Additional CV input for Filter Bandwidth.
  • Various minor tweaks and bug fixes.

Filter is a versatile and lush-sounding digital filter unit, which integrates seamlessly into our Elements modular series. It combines a freely assignable envelope follower with a comprehensive filter section, complete with 10 unique filter types. In addition, it can plugged into DS-LFO for modular stereo CV manipulation.

Typical applications include: Classic filter effects; dynamic wah-wah effects; DJ-style HP-to-LP filtering; advanced dual peak filter effects, pre-distortion/lo-fi overloading; evolving stereo filtered textures.

Filter is available separately, or as part of our Elements bundle.

Product details


Filter features 10 distinct filter types, each with its own unique character, from the bread-and-butter 2-pole LP, to DJ-style HP/LP hybrids. “2x” filter types combine two filters in series or parallel and allow their respective frequencies to be offset, creating a vast range of possible tones.

With such built-in flexibility, Filter is not only the definitive digital filter go-to, but also an unsurpassed source of inspiration.

Included algorithms:

  • LP2
  • LP4 (2x LP2)
  • HP2
  • HP4 (2x HP2)
  • BP2
  • BR2
  • 2x BP2
  • 2x BR2
  • DJ HP/LP2
  • DJ HP/LP4


Filter features the same dynamic modulation that made our Multiband series so popular. With Filter’s on-board envelope follower, which is freely assignable to all the major controls, you have full access to depth and feel of the modulation.

Combined with our rich selection of filter types, the potential for audio sculpting is essentially limitless.


In line with the modular philosophy of our Elements series, Filter features stereo CV inputs on primary controls, which when hooked up to our DS-LFO device (available separately for FREE), provide additional, fully customisable stereo modulation.

This is an exclusive implementation which truly embraces Reason’s modular concept and allows for effects which were impossible... until now.


Elements is a series of mini devices derived from our Triad Multiband series. Each device has been carefully crafted to isolate and enhance specific “elements” of Triad, and integrate together modularly, through stereo CV modulation and slick, unified design.

Used either as standalone devices or as part of a modular or multiband setup, each Element is an exceptionally creative tool for sound designers and musicians alike.

Whether you're after wild and wicked sounds or a fresh array of bread-and-butter micro effects, Elements are simple yet versatile enough to become a staple in any Reason-head's arsenal.

They are, after all, elementary.
