HoRNet SyncPressor

HoRNet SyncPressor 1.0.1 is out, this update includes:

  • Fixed tempo detection with sample rates higher than 44100
  • Fixed external side chain affecting only left channel in Pro Tools when unlink was activated
  • Fixed wrong report of oversampling latency
  • Added new presets

The update can be downloaded from your user area

A compressor that goes along with your track

SyncPressor is a dynamics processor designed for the master bus, it’s a collaboration between HoRNet Plugins and Antonio Porcelli, a top Italian  mixing engineer and it’s a plugin that aim to provide “glue” to your mix while being transparent.

The effect is accomplished using a simple assumption: the compression moves dynamically with  the track so attack and release time should be set according to the track’s tempo, for this reason in SyncPressor you will not find the usual attack and release knobs, but two dropdown that use time divisions relative to the compressor’s internal tempo, which in turn can be synched to the DAW, set manually or automatically detected from the audio.

With this trick the time constants of the compressor will always be set to a useful amount for your track and will never work “against” it.

HoRNet SyncPressor can also work as a track compressor, so you get the usual compressor settings with variable knee, RMS mode, feedback processing, external sidechain and an HP filter on the sidechain detector (both internal and external).

Another master bus specific option is the ability to “unlink” left and right channels in the internal detector so that the compressor actually works like a “dual mono” processor compressing left and right channels individually; this trick gives you a wider stereo image and it’s one of secrets for a high level mix.

Finally a dry/wet control allows you to mix back some of the “clean” unprocessed signal and a “tempo multiplier” setting lets you double or halve the attack and release times to quickly try out different combinations.

HoRNet SyncPressor uses a fully hardware accelerated GUI using OpenGL on windows and Metal on macOS so the CPU is left for audio processing.

Including presets from top Italian engineers

Antonio Porcelli

Antonio Porcelli lives in the south east of Italy, in beautiful Puglia and he’s an Italian sound engineer. He is mainly known for his work with Caparezza. His name can be found in records together with with Chris Lord Alge, Gavin Lurssen and Reuben Cohen.

On the live side he has done shows all over the world, Italy, Europe and the United States.

Davide Linzi

Davide Linzi is a FOH live sound engineer (Negrita, Ultimo, J-ax, Francesco Renga) and he has always cultivated a great passion for the studio, creating many projects by local artists. He likes to blend the two working approaches trying to bring some techniques of the live in the studio and vice versa to recreate the sound he has in mind. He recently got to know the world of Hornet plugin and found then very versatile, musical and above all creative tools: new possibilities. He tried the Hornet SyncPressor on the advice of Antonio Porcelli and found it very flexible and transparent. The ability to link attack and release times to song tempo is brilliant and makes it suitable for both mastering and single elements of a mix.

Nicola Fantozzi

Nicola Fantozzi started working at the historic Fonoprint studios in 2000, where he had the opportunity to work with the most important Italian productions. He was thus able to undertake the path of mastering with artists such as Ennio Morricone, Zucchero, Lucio Dalla, Luca Carboni and many others. In 2006 he became freelance and started working with Laura Pausini, contributing to the realization of all her albums from “Io Canto” onwards. From 2014 he started collaborating with Cesare Cremonini, of whom he recorded and mixed the latest records, including “Logico # 1” and “Più che Logico”. He has numerous platinum-certified albums to his credit, including three Latin Grammy winners. He recently opened a new mastering facility, Level Mastering.

Simone Squillario

Graduated in 2003 from the “Scuola di Alto Perfezionamento Musicale” (APM) in Saluzzo, since then he has collaborated as live engineer (FOH) and studio engineer (Mix / Mastering) for numerous artists: Salmo, Africa Unite, Levante, Casino Royale, Primo Maggio Rome and many others.


The demo is fully functional except for the fact that every now and then it will silence out, you cannot save parameter values with your session and the plugin will not respond to automation coming from the host.

Copy protection

The HoRNet SyncPressor has no copy protection, we 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've got several good compressors but I'm starting to use syncpressor a lot. Not only does it sync to the DAW's tempo, but it sounds good too.

macop says:

Excellent. Easy to set up, nicely glued and transparent. I like.

Christoph Wardzinski says:

It saves a lot of stress and lot of time, glues things perfect together, sounds great. I am really happy to have this vst. 🙂

Maciej Nowicki says:

Great compressor !!!


All your plugs could use this design template! Great work.

Ne Si says:

My favorite mastering compressor.

Jordan says:


Ce compressor, calcule l’algorithme de la track sonne très transparent et pour moi ce compressor peut aller titiller de très gros compressor merci hornet 😉

Mihail-Bogdan Yanov says:

Great sound, great value, great idea!

I would only add the option for the attack and release to be individually synced or un-synced by choice.

Its great that the compressor shows you the notes in millisecond values and if you could disable sync you could get the compressor to move a tiny bit faster or slower than the sync tempo for creative and more versatile results .

Robert Jauner says:

Hi, nice ideas about parameters to go straight to mastering settings with good Sound.
A wish : in metering levels, showing (reading) peak value would be great

Great job! Grande lavoro! Ottimo! Grazie!
