RMS COMPRESSOR

P11 ABYSS

Clean enough for the master. Dirty enough for the drum bus.

Abyss is an RMS compressor with a pressure control where other compressors have a circuit type. PSI runs from 0 to 10 and changes how attack and release behave at every tenth of a step, so one instance covers the ground of a VCA, an opto and a variable-mu without imitating any of them.

A compressor without a family tree.

Engineers learn compressors by family. VCA for deep, aggressive punch. Opto for clean, open, smooth action. Variable-mu for flowing, rhythmic pulsing. Abyss was built so you would not have to choose.

In place of a circuit model, Abyss gives you controls that reach into the character of the compression itself. PSI sets the pressure. SOUL sets how much of the device is in the signal. MOD switches in a second amplifier stage, tuned by ear. O2 is a Pulsar Modular circuit that opens the sound after everything else has happened. None of them sits on top of the sound as a layer; each one changes how the compressor reacts.

It is an RMS compressor, which changes the numbers you reach for. The guide's advice for buses and masters is to try longer attacks than you are used to, 100 to 150 ms if the mix feels choked.

PSI. The knob that decides what kind of compressor this is.

PSI shapes how Abyss responds to audio before threshold, ratio or the time constants come into it. At high pressure the compressor reacts with force. As the pressure eases it turns calm and transparent. Every 0.1 step adjusts the attack and release character, which is why one instance can stand in for very different hardware.

I have already used P11 Abyss on several masters, and it has quickly become one of those plugins that makes me question whether I can go back to working without it.

What I appreciate most is the way it helps the sound settle into place. The master feels more cohesive, more refined, and more expensive, but not in an obvious or over-processed way. It adds a sense of polish and class while still allowing the track to breathe and retain its original identity.

P11 Abyss is certainly not a cheap plugin, but in my experience it brings more value to a track than its price suggests. The improvement is not just technical; it changes the perceived quality of the master. The music feels more finished, more professional, and more like something that has passed through a serious mastering chain.

In that sense, the price starts to feel very reasonable. If I think about the cost of using high-end outboard gear or booking time at a professional mastering studio, P11 Abyss almost feels like a surprisingly affordable investment. It gives me access to a level of tone, glue, and refinement that would otherwise be much harder and much more expensive to achieve in the box.

For me, P11 Abyss is not just another compressor. It is a mastering tool that can give a track a more luxurious, integrated, and complete feeling. Every time I bypass it, I notice how much of that subtle depth and elegance disappears.

It has already earned a very important place in my mastering chain.

Oh dear... How is it possible that P11 makes all my compressors absolete? How is it even possible it can morph itself in an 1176, a vari-mu, a VCA bus compressor?
Abyss make the others sound pale, one-dimensional.

At the start, the amount of knobs is kinda overwhelming (hence the name) but the presets helped me out. And after a few hours of tweaking, I found my way.

And after a day of A/B testing, I had to rework all my templates and said goodbye to the SSL, API and Unfairchild.

Highly, very highly recommended!

This is a nuanced compressor. As others have stated, a "desert island" comp. Don't think you'll get everything out of this on day one. But if you put in some "honeymoon' time, it will will NOT disappoint. Truly earns it's name as a masterpiece. So many uses I'm just amazed as to the character and personality. Huge win for all of us that work in the box. Thank you pulsar Modular team and please keep them coming!

I use Abyss on my kick and bass channel and always use the limiter for clipping transients. Love the transformers for coloring the sound. The plugin also has many other useful parameters, such as the two EQs, for achieving the sound you want. The delta function is also very useful.

Took me a while to get to know it, but I'm using this on more and more tracks as I figure it out. A bit of subtle tweaking and re-tweaking can dial in more or less any type of dynamic control I need, with a surprisingly straightforward work flow. Not for a total novice perhaps as there are several ways to get into hot water with it, but if you don't reach for the knobs until you know what you want it to do, I think its a really great swiss army tool.

Great compressor. Because of the transformer saturation, it can be made cleaner or colored. At first, the sheer volume of features may be overwhelming. For instance, this one has Variable Linking, a Clipper, a Limiter, and the standard Threshold, Ratio, Attack, and Release. As is typical with Pulsar Modular plugins, it is worthwhile to take the time to learn this one.

P11 Abyss
This is the compressor that ends all compressors—and that’s coming from someone who owns just about every software compressor out there. Before the P11, my workflow was scattered: an LA for vocals, a 2500 for drum buses, a 76 on snares, kicks, bass, and guitars—but I was never completely satisfied. Each session felt like a guessing game, swapping compressors and second-guessing my choices.
The P11 changed everything. It just works—on anything. For the first time, a plugin compressor feels truly comparable to my hardware units. I own several stereo analog compressors, and this is the first plugin that captures that unmistakable analog vibe. In fact, I was saving up for another hardware unit, but after hearing the P11, I used that money to buy this instead.
What I love about it:
Versatility: From single instruments to buses to the master bus, it handles it all with ease.
CPU Efficiency: Hugely important for big sessions—no performance worries here.
Analog Character: On the 2-bus especially, it does something magical to the stereo image that most plugins simply don’t.
If you’re on the fence, try it—you might rethink your entire compressor lineup.

Once you take the time to learn P11 Abyss like an instrument, you realize there's just no end to the things this compressor can do. It truly puts to rest the superstition that analog is just better, and feels alive in a way few ITB compressors ever achieve. It's even a bit intimidating; all the better to master it!

This compressor can handle just about anything you'd want from a dynamics processor.
Being an RMS-based design, it may not offer the tightest control on percussive elements like drums—but that's a trade-off.
Everything about this plugin feels top-notch to me: the saturation, sidechain EQ, clipper, and limiter all sound excellent.
The PSI knob is especially unique—it can either tame a sound or make it snap, depending on how you use it.

A while back I went on a serious deep dive in trying find my ITB Compressor. To me, the P11 ABYSS is way more! TONE! It has a sound... actually it can have many sounds, shapes and characters. I remember while demoing it, I pulled up my go to compressors and then in P11 ABYSS, I tried to recreate what they gave me. At that time with the P11, I was able to recreate sounds and characteristics that were spot on, and some that were not (I'm sure it was due to my lack of, or not taking enough time). BUT, whatever I wasn't able to recreate, was quickly made up for in what the P11 ABYSS had to offer! Goodness... O2 is so killing!!! Modes and Saturation!! It's pretty crazy and I'm still now learning it more and more. Mixing, mastering as well as shaping sounds and tones, I'm a fan!

This was my entry into the Pulsar Modular catalog. Being just a hobbyist/ singer songwriter, I still saved up to get the P11, seeing the potential in it for myself, against all the talk about it being just another expensive compressor. That took me almost a year as it is definitely not a small amount to come up with.

It is a difficult compressor plugin to learn. I found it very challenging and yet, I also found it to be absolutely rewarding. It is very versatile and it is possible to shape, or should I say achieve the sound that you have in your mind, by simple tweaking the parameters in the plugin. Discovering which parameters to tweak, is the journey that this plugin will take you on.

Is it worth it? I reckon you have to decide that for yourself. There’s a good demo period. Do I recommend it? Yes, but only if you’re willing to spend some time with it, to learn all the controls and figure out what it can do. It surely works as a normal compressor, but if that’s all that you want, you’re paying way too much for it.

This is a mainstay on my vocal bus, my guitar bus and my drum bus. I only do not have it on my 2bus as that’s where I have the new MDN Sidecar. ????

This compressor has a learning curve because it packs such vast amounts of features, but thankfully it also has a long list of starting points in the form of presets that actually are very useful, perfectly descriptive and instructive (that's rare in my experience). Once you try a few of them out, the many features will start to make sense, and you realize just how massively versatile and sweet-sounding this thing is. It is transparent if you want it to be, and if you prefer a colored, sweetened sound, it has that too. Give the transformers a spin and you'll see what I mean. Open up the upper register with the O2 knob. Let in the vintage vibe with the dedicated slider. Oversampling options, fine-tuning frequency response for the compressor... It's the ultimate finishing compressor on the mix bus for me. I know it can do radical things, but my preference is to find beauty and added space to the full mix with it. It's very forgiving, and it's frankly hard to make it sound bad no matter what you do. There's a really generously timed demo available that you can renew twice, so you can try everything out over time. Do read the manual. It's clear, almost crucial, and detailed. It's an expensive tool, yes, but it's definitely worth the price, and unlike many other plugin makers, Pulsar Modular keep refining their products instead of releasing new ones all the time, and so investing in a great device like this one pays off. I'm still learning about things it can do, and my mixes are sounding better lately thanks to it. Warmly recommended.

P11 Abyss has quickly become my favourite compressor. It is very flexible, easy to use, CPU friendly, and it sounds amazing.

It does cost quite a bit, but considering how many compressor plugins I own, I imagine I could've made a saving had I had the chance to invest in it some 20 years ago. After purchasing it, P11 Abyss has replaced most other compressors in my daily use.

Even though Abyss can be set to destroy, especially with its saturation and clipper features, for absolute crushing of signals I still turn to other compressors. Other than those cases, Abyss has quickly become my go-to compressor regardless of the project.

It may not be perfect, but it just might be the best software compressor I've ever used, and it certainly is my favourite at the time of writing this.

I've been using the P11 Abyss compressor plugin for a few month now and I'm very satisfied with its performance. The sound quality is simply exceptional - every sound that passes through the P11 Abyss becomes richer and deeper, while remaining clear and detailed.
The compression settings are particularly impressive - I've been able to get subtle and gentle compression effects for vocal tracks (O2 is magic for vocals), as well as more aggressive and "crunchy" effects for drum and electric guitar tracks.
The P11 Abyss is also very versatile and can be used in many different situations, thanks for the differents topologies. I've successfully used it to compress voice, guitar, bass, drums, buss, and even synthesizer tracks.
Finally, the P11 Abyss is a very stable and reliable plugin that doesn't seem to slow down my system or cause crashes, very friendly CPU usage. It's an ideal choice for musicians and producers looking to add a professional touch to their sound without the need for expensive analog hardware.
Overall, I highly recommend the P11 Abyss compressor plugin to any musicians and producers looking to improve their sound and add a unique touch to their mix. It's an excellent investment .

The ultimate, do it all compressor....which of course has been said about some of the other top tier plugin compressors of more recent vintage. In the case of the P11 it is true. If one understands well how to use a compressor, there's very little one can't get out of this plugin, and if you explore the presets, even more possibilities become readily apparent.

All this would be nice but unremarkable, but it's the sound, colors, and options available that set it apart from almost every other compressor plugin available. It has become my first choice in almost every instance when compression is needed.

And if that were not enough, the developers continual improvements and/or feature additions in response to users feedback is truly top tier.

My only regret is that this was not available a few years earlier as I would have saved multiples of the price of this compressor in terms of what it has easily replaced.

This is an expensive plugin, but a bit counterintuitively it's excellent value for money.

For one thing I've pretty much stopped buying compressor plugins since I bought P11- whenever I shoot it out against something new and shiny I invariably appreciate P11's version enough that the other compressor doesn't quite seem worth the cost. For that matter, I've actually been selling compressor plugins that aren't getting used any more.

Another way P11 is a great value is that Pulsar Modular seems very dedicated to continuously improving their offerings, so P11 just keeps getting better and better. This is a bit of a rarity in the plugin world, and worth supporting.

Finally- and I feel others have covered this more eloquently than I can- P11 just sounds great. Really great. It and Pulsar Modular's other offerings have raised my standards for the tools I want to use.

I don't think you'll regret buying it.

P11 Abyss is a brilliant tool to have your toolbox. I find it encourages me to listen more intently and to not care so much about the numbers. What I like about it is that is really has a wide range of sweet spots, it is very difficult to make it sound bad. When you really get it dialed in though it becomes very apparent and in bypassing it you feel the difference. It is great for any compression task, and if you want to go deeper it has a plethora of features to further help you, such as the EQ, saturation, clipper, limiter, expander mode.

I love Abyss like I love Climax. Both are great plugins!! Pulsar Modular Plugins sound way more organic, lively and analogue than most of the other plugins I own. Thank you!

Abyss. A polarising plugin that quite possibly needs you to consider your approach to mixing by numbers and really listening. Use the full 40-day trial and really explore the features, there is a lot here and it genuinely can replace 3 plugins, saturation, EQ, not to mention the actual compression. This is not an ordinary plugin, settings that work on your usual cadre of compressors will not translate 1:1 here but when you learn to let go of the numbers, this plugin really shines on individual channels, busses, and the 2-buss.

I was pretty late to PM products but started with P11 & P42 following a successful demo period, it really surprised me how much better my tracks sounded (sometime with only minimal processing). P11 in particular just keeps getting used! Having a number of other compressors I'll occassionally try something else out of interest but find myself returning to P11 everytime as it just seems to embellish the sound without losing the original character. Only a couple of months in and I am still learning my way around its functionality but its well laid out interface is reasonably easy to understand & navigate and gotta say I find the presets (& preset guide) really helpful when exploring its capabilities. Yes this is a considered purchase but I have no doubt it has improved the quality of my tracks and that, to me, is just priceless.

If your an "In The Box" (ITB) compressor user then it doesn't get any better than Abyss. The sound quality in Pulsar Modular's offering with Abyss is as good as it gets. It looks complicated at first but i found it very intuitive. Unlike some plugins, the smooth operation makes this thing a pleasure to use as you sculpt your sound. It offers a good range of tones when you need it or can be buttery smooth and transparent. It covers many styles of compression with lots of control to boot.

Abyss comes with some presets that are great to show off the variation it has to offer as a good starting point. Once you start dialing in Abyss it really opens up what this thing can do. It has retired a lot of my ITB plugins because they simply can't compete with the quality of Abyss. The GUI is pleasing to the eye and the metering is clear, smooth and responsive. The saturation is really nice, something Pulsar Modular does really well. The low CPU usage is a bonus for a plugin of this quality compared to others i have tried.

I highly recommend you to try Abyss, if your looking for some of the best ITB compression 2023 has to offer.

Please believe all the hype you’ve read. This is an exceptional mixing and mastering tool.

I have to intentionally remind myself that not everything needs a compressor as this tool is easily very addictive.

I have been using this bad boy for a couple of months now, and it has quickly become my go-to for coloured, vibey and alive feeling compression. There is a lot of special functions in here that you won't find in many other compressors and definitely not these exact ones and surely not all of them... O2 is sweet on almost everything. The EQ is great. The MOD and SOUL controls work for me sometimes, but it is good to have the option. Oversampling almost always sounds better. The clipper is quite transparent sounding until you crank it. My go-to for uncoloured compression is Massenburg DRC, btw.

I got interested in Abyss while testing the Acoustica compressor, that infamously sampled/analyzed Abyss and I found that model to be the only one I cared for in that plugin. After demoing Abyss, it took me minutes to commit to a purchase. Sure, it is a lot of dollars, but to me it is not expensive, because you get very good value for your money and it replaces - and surpasses - most, if not all of your other compressor plugins, IMVSVHO. It is surely a tweakers dream, but it is luckily also quick and easy to get a good result starting with the excellent presets or from the default setting.

Try it only if you have the cash to spend!

Abyss is an excellent compressor. The sound is unique. It has a lot of settings, which is also a gas factory. When handled well, it is great, and not very CPU intensive. I like the Auto release and attack modes, as well as the EQs that allow you to go even further in the desired effects. The only thing missing is an AI that would help to find the first settings, like an assistant.

This compressor is a beast. It has a lot of parameters and ways of manipulating sounds both dynamically and tonally. This is one of its biggest strengths and weaknesses.

On one hand this compressor is sonically up there with the absolute best sounding compressor plugins and may even beat out all other plugin compressors. It has such an organic feel to the way you can manipulate transients, groove, and the envelope of a sound. That along with the great number of saturation, clipping and limiting parameters makes it one of the most versatile tools out there.

On the other hand it’s all a bit overwhelming at first. It’s not the type of compressor where you lower the threshold, raise makeup gain, and call it a day. It takes awhile to just begin to understand all the parameters and how they work together. Once you start to get it though, this could be used for most compression tasks, but subtle and heavy handed.

One last note on the price. This thing is quite expensive for a plugin. It’s possible it’s too expensive for most people. I will say though that if you have bought several compressor plugins to get different sounds, the concept of this covering many bases starts to make more sense financially. I wouldn’t say it’s a great deal, but the price makes sense in my opinion.

Really liking this compressor. Glad we made the "leap of faith" while in early stages of development and got to see and experience the features while it was being developped.

We like the fact that it covers a vary wide range of uses and scenarios and how versatile it is thanks to its extensive feature set and setting capabilities. However, for the very same reason, its learning curve is somewhat steeper, as you have to learn, understand and test around with many more features and settings. But once passed the learning curve, this comp becomes a real workhorse, replacing many others in your toolbox.

I do however agree on a previous comment, suggesting to add in a future update a Peak or RMS toggle for the detection circuit (to switch from its current RMS detection mode to a Peak detection mode), or even a knob that gradually scales between Peak or RMS detection.

Overall, a great plugin by a great and devoted team! Props!

P11 Abyss has a fairly complicated architecture which gives it the ability to cover many styles of compression. It has been replacing other compressors for me as I have been doing shootouts. Because of its flexible architecture, it can be a little daunting at first. This is made up for in wide palate of sounds as well as having one of the best manuals I've seen in a plugin.

The Pulsar Modular team put in a lot of hours doing comparisons and has provided many presets which dial Abyss into the neighborhood of world class hardware compressors. I use these as templates to start dialing in my own sound.

Dig in to all the rich tone features and cornucopia of controls-I've decided to invest much more into really understanding this compressor-which has led me out of the cycle of new compressor desire and into the much better position of mastering just this one. I do still have a few others for very particular cases, but it is helping me narrow down and be more productive in recording. Because of Abyss, I'm skipping expanding my hardware compressors. It really is that good.

Buy in to Pulsar Modular is high, but there is a loyalty system and definitely follow the threads on the forums as there are opportunities in them (especially for people sharing tips). Don't forget the transformer saturation...Pulsar know how to do saturation (P42 and Siren too!). This is magic on a drum bus.

I am impressed with Abyss, mostly as a mixing tool. I find that Abyss is a fantastic multi-purpose compressor. I have it set up in my mixing template for most of my tracks, which seems to save me time and makes the process more enjoyable since I could replace several different compressors with this one. I have also had great success using it during stem mastering sessions.

Since starting my journey with Pulsar Modular I've found many of my wealth of mixing tools have been reduced to residing in my digital storage box. This journey started off with P42 climax, then Lunar Lander, P565 Siren and most recently P11 Abys. Now at least a couple of these beautiful tools gets used on every mix I do. I've found P11 Abyss a real joy to use as I find it very easy to dial in the sound I'm after quickly. It feels to me like I'm using hardware but with the advantages of digital plugin. And it's a real chameleon, giving me fast results and with a tiny cpu footprint. Quite simply of the 25 of more compressors I own P11 Abyss is without doubt king. Don't miss out and give it a go.

Highly recommended, versatile and powerful compressor! Some room for (minor) improvement from my perspective: Quite a few features were added due to feedback in the late beta phase, which is great, but it also complicated the UI/UX slightly - some new features feel a bit "tacked on" GUI-wise and less streamlined.

This is such a fun compressor to use. It is capable of many different tones and types of compression dynamics. So much thought has gone into the controls that it really pays to tweak it and get to know it. Abyss also looks amazing with Max P of Nebula fame having created two really distinct UIs with the developer.

Top class release!

Abyss has quickly earned a top spot in my compressor go to list. You can get some amazing dynamics and tone shaping out of it, and it richly rewards taking the time to learn the deep but not overly complex feature set. Worth reading the excellent manual for sure.

Careful listening while setting the parameters is a must, the attack and release times don't necessarily correspond to what you may be used to with other compressors. It's an RMS based topology which accounts for the differences. Could be cool in a future update to have a Peak or RMS toggle for the detection circuit, or even a knob that gradually scales between Peak or RMS detection.

It's obvious a lot of sonic love and attention to detail were given while crafting this beast! The developer is very engaged and responsive as well which is a huge plus. Highly recommended.

My favorite compressor for sound design, beat making, mixing and mastering. Once you get the flow of this compressor (please read the manual) you will not look back. Learn its unique parameters. Then sit back and enjoy barely any cpu hit in the process, as well as zero latency. Expensive yes, but well worth the investment for workflow and not having to waste money on multitude of compressors. Dev is always on top of his game with updates and fixes too when needed. Be like Nike and "Just do it!"

P11 is not good, it's great! It has replaced my hardware 2Bus compressors allowing me to work from anywhere with uncompromised sound quality.

What I love about the compressor is that it covers an incredible range of compressor varieties and sounds.

On the drums, it does anything from subtle to gritty- depending on how you set it up.

On the mix bus you can easily get the compressor to barely compress the material yet somehow you will see a 1.5 to 2dB peak reduction, which gives you a ton of headroom for limiting, while giving a noticeable increase in clarity, glue and punch. I believe it's not only compressing but also expanding the low signal- whatever the reason, it sounds great on virtually any song I've tried Abyss on.

I still need spend more time learning how to set it correctly on vocals and instruments but its value as your 2-Bus compressor makes it easily worth the money.

My first impression is that it really is a very good plugin. The problem is that the price is beyond all my possibilities, even more so in my case that I am a "pro fan" to make music and mix. I'll have to be patient until I find it at a price I can afford, but I love it!

I've been looking for a good compressor for a long, long time... No joke, when I tested this compressor, I fell out of my chair immediately. Then I looked at cpu usage "below 1%".... I'm typing from a hospital right now, because this thing is so sick that I got sick too

cons: I'm not rich... :\
