New Plug-In: Cheeseverb, an Analog BBD Reverb!

Announcing our new analog BBD reverb with a lo-fi dark ambience...

Flipper is back!

The free Flipper polarity reverse plug-in is back.


  • Classic dual-band subharmonic architecture
  • Gate, drive, and output filter controls
  • Operates in 3 different frequency ranges to match program material
  • Analog modeling - no FFT shenanigans!

Audio Samples

Each selection plays dry first, then is repeated with the effect added.

A bass figure, first mixed normally, then with the Lowender set with a touch of drive and the lowpass up, to let it growl a bit.


From post-production houses to disco floors, from high-powered live sound to rock, dub, and metal studio productions, the characteristic rumble of the subharmonic synthesizer has been an engineer’s best-kept secret for years. Now, finally, you can get those low lows from within your favorite DAW application!

While taking the classic “Boom Box” sound as its core, the Lowender expands on the concept in several ways. First, it offers switchable frequency ranges, so that the low end frequencies generated can be selected to fit the program material.

Second, the generated subharmonics pass through a gate tailored for low frequencies, which is useful for cleaning up unwanted bass rumble (e.g. from between kick drum hits in a drum loop).

Third, the Lowender passes the bass material through an output section comprised of an overdrive circuit and a lowpass filter. Driving or compressing the newly generated low frequencies is essential for evening out their dynamics, and will allow them to sit well in a mix. The variable lowpass filter is provided to shave off the higher harmonics of the overdrive and create a smooth low end - or you can leave some of them in, for raspier bass sounds.

Version 1.4 features these changes:

- Fixes a graphics bug where the Lowender window would not be scaled properly, resulting in parts of the GUI being cropped
- Fixes a bug when copy/pasting plug-in settings in Pro Tools
- New authorization keyfile format and location - registered users must log in and download a new license file

Version 1.3 featured these changes:

- AAX support added
- New authorization scheme using a keyfile instead of text entry
- Gate level-detection algorithm improved
- Utility bar now appears below main plug-in window, rather than obscuring the bottom strip of the existing window
- Fine control shortcut changed from Shift-drag to Command-drag (Mac) / Ctrl-drag (Win)
- Known Issue: Pro Tools “Compare” button is not functional.

Version 1.2 featured these changes:

- 64-bit versions for VST and Audio Unit
- Popup Utility Bar! Access by clicking “reFuse” logo:
  - Authorize or Deauthorize plug-in
  - Shows username registered to
  - Shows numeric parameter values
  - Check for updates
- Changed Blender’s default setting to 75% (default bass level is now quieter)
- Fixed Master Bypass automation in Pro Tools

Supported Systems

Lowender requires macOS 10.6 or higher (except for the AAX version which requires macOS 10.8 or higher), or Windows XP / Windows 7.

AAX, VST, RTAS (and AudioSuite), and Audio Unit (on Mac) versions are provided. VST and Audio Unit include both 32 and 64 bit versions.
