HoRNet Valvola

HoRNet Valvola 1.0.1 is available, this update is free and includes:

  • Fixed issue with Logic Pro not validating the plugin
  • Fixed cpu spikes on some DAWs on windows

Realistic vacuum tube sound and behavior

HoRNet Valvola (the Italian word for vacuum tube) it’s an emulation of the electric behavior of a vacuum tube and its surrounding circuit.

The sound of the plugin is as close as you can get to the real tube behavior since the code it’s the direct modeling of the circuit characteristics obtained directly simulating the tube and the biasing circuit around it.
The same technology is found inside our Guitar Kit plugin and Analog Stage plugin and we decided to give it away for free because we are proud of it.

Valvola comes with many different vacuum tube emulations, including triodes and pentodes, from the classic 12AX7 used in pre amplifiers to the EL84 power tube, well using more than one instance of Valvola you could create your little tube amplifier emulation.

The typical tube distortion that Valvola provides is not static but changes with your music since tubes has some kind of “memory effect” that actually change their bias point if they processed high levels (this is the case with heavy bass drums, bass synths or guitars) in practice they distort more with low frequency peaks. Also vacuum tubes are not linear in frequency response and each one has its own characteristic sound that we carefully modeled using the original tube parameters.

All these interactions are controlled using just one “saturation” knob that also keeps the level constant so you can just add distortion without adding gain and keeping the aliasing at minimum thanks to the intelligent oversampling up to 4x.

HoRNet Valvola comes with an hardware accelerated graphic interface that is completely resizable and drawn using vectorial techniques so that it looks sharp and perfect on every monitor size.

We also added the “load” and “save” buttons so you can quickly create your presets and reuse them in your projects.


  • Tube circuit emulation using electrical simulation
  • Seven different tube types including triodes and pentodes
  • Intelligent oversampling up to 4x
  • macOS (10.11 and later) and Windows (Vista and later) support.
  • 64-bit only on both on Mac and Windows.
  • Audio Units VST2.4, VST3 and AAX format.

Copy protection

The HoRNet Valvola has no copy protection, I don’t believe in copy protection, they are always cracked and they are annoying for the users, we all know you are not going to give away the plugin on the internet…

So simply download the plugin and enjoy your recordings!

I did the share link but it still won't let me have it

Lorenzo Buhne says:

Can't wait to try it!

Donald J Trufan says:

I confirm another review.
This plugin DOES NOT WORK in Cubase!

Cleveland says:


chynakym says:

Just downloaded and confirmed it is not working on SoundBridge DAW. I was so looking forward to testing it but I guess it will have to wait for the next update.

Darko says:

I will try it!

Michael Keuter says:

Crashes the plugin validation in Logic 10.5.1 under macOS 10.14.5 (Intel).

vicci fontaini says:

Can't get it to work in Reaper, outputs silence.

Thank you and Merry Xmas

vicci fontaini says:

VST2 version works, only getting silence from VST3 version

Massimo Fasciano says:

VST3 outputs silence in Reaper. VST2 works perfectly. Sounds really nice. Hoping for a quick fix.

Joe Malinovsky says:

Can't download it. I don't use social media (except for You Tube audio channels) so can't share. Bummer for those of us who don't play the social media game.

Erik Miller says:

Confirm VST2 working, VST3 silent in Cakewalk by BandLab.

Sounds like a nice enough little tubifier.

Andrei says:

Logic Pro X 10.5.1

Crashes the plugin validation.

ks says:

Cannot download. My adblocking DNS breaks the page.

JB says:

No social media buttons are allowed in my browser. Would love to try the plugin.

moloko says:

VST3 working fine on Reaper, super easy to download and so far it sounds excellent! Thanks for the xmas gift <3

alexander plasko says:

No Facebook or twitter accounts
Thanks anyway

David Beneke says:

Great Plugin!

Poo Ping says:

This looks like a cool, straightforward plugin. Hopefully you'll let people without social media pick it up–I deleted my accounts almost 3 years ago and have no plans to ever return. Still, thanks for the great plugins and hope everyone has an awesome Xmas!!

Sascha Franck says:

Just here to confirm it's not working in Logic 10.5.1

Lorenzo says:

Would love to try it and I am unable to find a download link for it after the Facebook write up. Where do I go?

Marius Lau says:

Reaper ver. 6 on a Mac with M1 works perfectly!

Joost Peters says:

Norton sees the DLL as a threat (medium risk) and automatically removes it when unpacked.

The info associated with it states that there are many indications that the DLL is untrustworthy and not safe.

I guess this is a false positive. Maybe you want to whitelist it to avoid confusion.

muy guay

Michael Keuter says:

Update: Version 1.0.1 works now on Logic 10.5.1 (macOS 10.14.6), but on Logic 10.7.2 (on M1) it says "the developer is unknown" (you must allow it in System Prefs/Security). To load the plugin in Logic you need to press "Option", otherwise it doesn't appear in the list of plugins. Very strange.

Erik Nyberg says:

Does not function in Cubase 11 on M1 Big Sur. Passes sound but… Not the sound that comes into it 🙂 Cool idea though, so looking forward to the fix!

Larry Cavallucci says:

I'm with Lorenzo…..NO download button after the one I hit in my email notice.

Massimo Fasciano says:

Still no sound from the VST3 after the first update. VST2 works fine (Reaper).

Daniel Cousins says:

Unfortunately no sound from VST3 in Ableton Live Suite 11.0.12 (Windows 10).

Obo says:

Tweeted, not unlocking for download in Safari. Bummer – would like to check it out and that was a bit of pain to get the tweet out finally…

Emmit H. Brooks says:

This will come in handy. Thanks for the gift!

gonziak says:

Testing love it so far.

JT says:

In the 1st release: VST 3 does not work in Tracktion T7, VST 2 works with minimal effect? I'll try the new release. Really nice and simple to use though.
Thanks for the holiday gift!

laurent roussel says:

I have no social network account so no chance to have it!

Tim says:

Can we have a paid version please? I'd like to just pay money instead of going to all the trouble of creating a Twitter account just for this. Please let us give you money Saverio!

godsoe says:

1.0.1 VST3 is also causing silence in Tracktion Waveform Pro 11.5.

wagner says:

muito top


VST2 works fine. VST3 does not pass audio using SoundBridge DAW.

Guillermo Torres says:

no he logrado bajarlo..

Joseph says:

Please just let me pay for this. I don’t use social media.

Christophe says:

Thank you

Daniel Cairney says:

If you are in FL studio and have no sound click the " buggy plugins" switch located on the wrapper- should work. and it REALLY works! Sounds excellent, smooth tube distortion that works really well with guitars letting the chords ring through before the distortion ramps up. Thanks for the free gift and hope to see more great plugins.

Daniel Cairney says:

Yes, the twitter/facebook thing is a downer. Make sure you POST your like in order to get the free download to work.

Music good
