Cathedral, Theatre, Haze and Mist...

Four deep reverbs for your KORG logue-sdk synthesizers

Video Demo

If you wish to use a more 'ambient' version of this reverb, check out Breathe (and "sniff")... These versions uses a little more reverb modulation, and automatically controls the filter cutoff.

As always, these are to be used at your own risk!

A quick word...

I've been having a ton of fun creating these plugins. If you like stuff like this and my other work, by all means feel free to contribute whatever you can to help support this!

Ensure you have the KORG minilogue/prologue sound librarian installed. Now, before you do anything else, perform a full and complete backup of your synthesizer and save this to disk before continuing. See the sound librarian manual for instructions on how to do this if required. Next, select the USER REVERB FX tab on the librarian, and drag and drop the requisite file(s) to an available slot in the librarian :

You should know there are two different types of each reverb:

  • files ending with "_pro" - these effects are designed to work with the prologue, and have a slightly 'thicker' algorithm. they can be used on the minilogue-xd and the NTS1, however do note that if you enable all 3 effects at once, dropouts due to FX CPU overload may occur. If you however just use the modulation and the reverb, you will likely be OK.
  • files ending with "_xd_ - these effects are designed for the minilogue-xd and the NTS1, where you can use all 3 effects at the same time. Note, the algorithm has been trimmed down a little, so you may notice a slight difference in the sound.
  • for minilogue-xd and NTS-1 users, you can use any of the .prlgunit files, currently the librarian accepts these as they are. See above for caveats regarding running the _pro versions of the effects on your minilouge-xd or NTS1.
  • for prologue users, while you can install and run either the _pro or the _xd versions, do note that the _pro versions are the effects 'as intended' - and are slightly more complex and can sound a bit 'thicker' than the _xd versions.

The effect type ("pro" or "xd") is also reflected in the effect name.

Also note : Currently, the minilogue-xd and the NTS1 do not support running user reverbs along with user delays. If a user delay is selected the reverb will be stopped, and you may have to re-start it by turning the effect off and on again, or re-selecting it (after you have unselected a user delay). The same goes for selecting a user reverb with a user delay selected.

About these reverbs...

Overall, these reverbs are similar to "breathe" (and 'sniff). A little less internal modulation is applied, and now the filter is fixed and manually controllable.

  • "Cathedral" and "Theatre" use a low-pass filter. The filter frequency is fixed, and controlled via the Depth knob. "Theatre" uses half of the reverb time as Cathedral (yet it will still support infinite feedback)
  • "Haze" and "Mist"are exactly the same as "Cathedral" and "Theatre", however the filter is now a high pass, resulting in a 'thinner' reverb sound.

As mentioned above, on the minilogue-xd and on the NTS-1, the "_xd" versions use fewer reverberators to reduce the CPU overhead to allow running factory delays along with mod effects and this reverb. You can still use the prologue version on the minilogue-xd and NTS1, but running this with mod effects and delays enabled at the same time may not work correctly and is not advised.


  • Time: Controls the filter cutoff frequency
  • Depth: Controls the overall reverb time. At 100%, this is 'infinite' - however, when the filter is allowed to reduce to minimum, this is slightly reduced to allow the reverberators to clear.
  • Shift+Depth: Sets the wet/dry levels. This reverb can be a lot of fun with a 100% wet signal.
If you wish to use a more 'ambient' version of this reverb, check out Breathe (and "sniff")... These versions uses a little more reverb modulation, and automatically controls the filter cutoff.

Play around with the settings and have fun!
