OrilRiver is a free algorithmic stereo reverb that can rival the quality of commercial reverbs. With this plugin it is possible to simulate the reverberation of a small room and great hall. OrilRiver has an intuitive interface thanks to which the user can quickly adjust the desired reverb sound.

Features OrilRiver:

  • 12 variations of the early reflections.
  • 5 variations of the reverb tail.
  • 3-band equalizer for the wet signal, which helps to create different shades of the virtual space.
  • Internal signal processing: 64-bit floating point.
  • Sample Rate: from 44100 to 192000 Hz.
  • Two graphical interfaces.

OrilRiver Beta Changes:
+ Increased the degree of influence of the controller "Diffusion".
+ Excluded the silence flag in VST3 version for more comfortably listening in real time mode for Cubase/Nuendo users.
+ Changed GUI for better its work.
+ Changed some factory presets using a low-pass filter.

I tried it, but I get a message that says that something couldn't find the access to something else and it doesn't load : (Is that a problem with my computer or the vst?

What are the characteristics of your computer and the system?

Hey Denis, many thanks for the great plugin.

There is a discussion opened about the reverb on KVR, in case you've missed it:

XP professional sp3, AMD athlon 64 x2 dual core processor 5000+, Cubase SX. As I said, it might very well be a problem with my set-up, so please don't go crazy trying to figure out what the problem is, unless others have the same problem :) Thanks :)

Works only on Win 7 and up, unfortunately, , , .

Hey, I think this is a wonderful reverb! Would it be okay if I had a custom GUI made for it?

29 September 2016 at 7:20pmMac of BIOnighT

Windows 7 and up only? Oh, that's a pity : (Thank you so much for looking into it anyway, Denis, I really appreciate it :)

Try the TAL reverbs, Reverb2 in particular. they work perfect in XP and sound fantastic.

Hi, this is a nice sounding reverb but none of the settings for the VST 2 version are remembered in Cakewalk Sonar X3. VST 3 seems ok.

What an atmospheric reverb plug! Great job Denis.

2 April 2017 at 5:15amEirikur

Wow! I am really looking forward to trying version 2! I'm a big fan of the first version.

Win10x64\Cubase 8\64 - VST2 - no GUI! VST3 x64 work fine.


3 April 2017 at 11:55amdenis_prophet

I will fix this bug.

4 April 2017 at 1:02ammr-es335

Hello, .

Windows 7 SP1 in MihiHost receive error OrilRiver.dll is not a valid VST plugin.

4 April 2017 at 3:41ammr-es335

Hello, .

Version 1.0.3, 32-bit works just fine.

8 April 2017 at 4:03pmdenis_prophet

OrilRiver has new build version. Fixed error displaying the GUI in the VST2 version in some hosts.

28 April 2017 at 9:13amPisces

Bug in version 2 beta. In FL Studio, doesn't save any settings with .flp project, everything zero'd on the plugin when the project is loaded. Very nice reverb. Great work.


28 April 2017 at 4:18pmdenis_prophet

I can not understand this.
I have tasted the OrilRiver in FL Studio 12 now and all settings saves well.
Please describe in more detail your problem.

I found some bugs, and maybe your problems are related to them. Soon there will be a next update.

2.0.2 Beta AU is not passing AU validation on Logic Pro X.

Hi Denis. Big fan of your plugin since the first beta version. For 2.x versions, the GUI updates in FLStudio are laggy (about 1 sec wait time between turning knobs, temporarily freezes FLStudio graphical updates) as if it were competing for graphical resources. I had no issues with the 1.x versions.


14 June 2017 at 8:38pmdenis_prophet

I found the cause of bug GUI. I will fix it.

14 June 2017 at 9:49pmnonnaci

Nice. Looking forwards to the next release.

5 July 2017 at 4:05pmdenis_prophet

Updated​ to beta 2.0.3. It has to work fine.

25 June 2017 at 2:13pmTaurus

Great Reverb, work fine here under Windows10 64-bit Renoise3.1.

17 July 2017 at 10:25pmAndersBrontosaurus

On my knees! This is awesome.

Thanks a lot for this gift Denis_Prophet.

Can confirm that it works on Win 8.1 x64, Jeskola Buzz.

17 July 2017 at 10:30pmpsyko66

Nothing has changed 2.0.3 don't pass AU validation on Logic Pro X.

12 August 2017 at 7:22pmmr-es335

Hello, .

Ver 2.0.3 Beta is working great in my 32-bit system.

This will be a "keeper" as well as my "go-to" reverb.

Well done, Denis.
