HoRNet Valvola

HoRNet Valvola 1.1.1 is available, this update is free and includes:

  • Fixed VST3 issues in various DAWs

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.
  • Apple Silicon native support (except for AAX)

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!

Tube saturation made easy. Sounds absolutely great, the vst3 working flawlessly, stacking several instances in front of an IRloader (e.g. AnyAmpIR) is a tempting idea.

Tom says:

nice one, as always. it's for free so I technically can't complain but auto gain would be awesome.. maybe in a update..? cheers

max says:

hey that is nice

Isaak Moagi says:

Great sound and minimal aliasing. What I don't like are the volume changes when switching between the tubes and driving the gain. It would be preferable if either the volume is automatically compensated at the output or at least all models start at the same initial volume level for better comparability and workflow. Constantly having to account for the volume changes makes it difficult to compare the sound.

Xan Piñeiro says:

I love warm sounds. Hotnet plugins always PRO.

Juan says:

Como todos los plugins de HoRNet, sencillo, eficiente y buena calidad.

Matthew Jones says:

Put this on snares, or your snare bus. It's pretty amazing. Really brings the life out of them. I was shocked. Very cool plug-in, very easy to use and low, low, low on CPU. Just do it!

Georg Pilger says:

Absolutely great value for price plugins. Must have! And amazing professional quality!

Massimo Fasciano says:

Version 1.1.1 appears to be working perfectly with Reaper (just did a quick test). The VST3 is now equivalent to the VST2 version.

Arias says:

Ahora si la version VST3 funcionando perfecto y estable, en mi caso en Cakewalk by Bandlab

Nicholas Shaw says:

I've just tried 1.1.0. The new circuit emulation sounds great. The output gain is very welcome and fixed my main complaint about the earlier version. However, I think that the gain should be increased to at least an 24dB boost to compensate for any drop in amplitude that the plugin causes at extreme settings, so I can volume match accurately.

godsoe says:

Version 1.1.0 VST3 still not working in Tracktion Waveform. It's addition to any track results in silence. VST2 version is working.

Massimo Fasciano says:

Version 1.1.0 VST3 still not working correctly in Reaper.
Have to force bus to 2 channels in IO properties otherwise no audio if kept in normal auto mode.
Graphical animation (glow) not working.
The VST2 version has been perfect from the start.
Please test the VST3 with Reaper.

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

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.


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

Marius Lau says:

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

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!!

David Beneke says:

Great Plugin!

moloko says:

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

Erik Miller says:

Confirm VST2 working, VST3 silent in Cakewalk by BandLab.

Sounds like a nice enough little tubifier.

Massimo Fasciano says:

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

Thank you and Merry Xmas

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

Вадим says:

HoRNet – есть плагин, который оч клевый и ставлю всегда в начале цепи

Alex Conti says:

Testiamo questo Valvola, che sicuramente non mi deluderà, come non lo han fatto i loro altri plugin
