TRANSFORMER SATURATION

P44 MAGNUM

The P42 saturation circuit, two new low-end circuits and a clipper built to stay musical.

Magnum began as a smaller P42 Climax and grew into a unit of its own. The A-11/12J transformer saturation comes from P42. OOMPH and POOMPH are new, two circuits tuned by ear for the range below 82 Hz, where most of a mix's weight lives. SWEET is a one-knob high-frequency exciter, O2 opens the result, and a clipper at the end of the chain keeps all of it under control without the glassy sound clippers usually bring.

THE FACEPLATE · CLICK TO ENLARGE

Years of advice have told everyone to cut the lows. Magnum was designed by people who would rather give them some OOMPH.

The saturation is the P42 circuit: a transformer stage that glues and densifies, smooths sharp digital peaks and raises the RMS of the source. INPUT DRIVE pushes harmonics into it, the SATURATION knob runs from 0 to 150 percent, and a switch places the stage before OOMPH and POOMPH for a more aggressive low end, or after them for a richer, smoother one. MOD swaps in an alternative circuit with a tape-like character.

The clipper sits at the very end, after the mix knob, and is always oversampled four times. With KNEE at zero it clips hard; raise it and the clipper engages gradually before the threshold, moving from tight and punchy toward smoother and thumpier. With MIX fully dry, Magnum is a clipper and nothing else.

WHERE THE THREE CIRCUITS WORK
OOMPH
Thump. Felt as an energetic low rumble, from the infrasonic 10 Hz up to 45 Hz. A smoothing slider shapes the lower edge of the boost until the bass sits right against the rest of the spectrum.
POOMPH
Punch. Picks up where OOMPH leaves off, 45 to 82 Hz, felt and heard. The two curves overlap at their crossover, sometimes as complementary bumps, sometimes cumulatively.
SWEET
A high-frequency exciter in one knob, sweet and crisp without harshness, and more than a combination of filters. FINE trims the bell part of its curve without changing the shape.

Another plugin that just creates the "Analog" sound. This goes on every bass track I've mixed in the last 2 years. Pure magic. It just sits the bass just right in the mix. It's great on lots of stuff! Just demo and try it. You'll be a believer!

Oh my, this is so good on bass guitar! I dime the "oomph" and "poomph", bring the saturation to about 50% and use the "sweet" to balance out the high end, then dial it back a bit with the mix knob (I find it's a little too heavy-handed in the low end 100% wet, even with the sliders set to 0%). I wish "oomph" and "poomph" had a *subtractive* slider instead of additive. Maybe in an update!

IIRC, it started as a lighter version of the P42 Climax. I still have the P42 Jr. In addition to saturation, this one has a clipper as well as options to shape a bit of the low frequencies (oomph and poomph) and high ones (sweet). Simpler than the P42, but very useful as well.

I grabbed the P44 Magnum since I wanted the best distortion plugin I could find.

Not only is the distortion and clipping aspects of this plugin great, but its use for more subtle saturation is not to be underestimated.

I didn't expect to be using this on my busses and master busses as much as I do, when looking to add or change the overall character of a mix in subtle to extreme ways, all while remaining completely musical and harmonic.

What I like:
* All-in-one convenience: Having EQ, clipping, and saturation in one plugin streamlines my workflow. It's quicker to dial in a sound without having to load multiple plugins.
* Sound quality: The P44 Magnum sounds great. The EQ is smooth and musical, the clipping is groundbreaking, and the saturation adds a pleasing touch of analog warmth.
* Intuitive interface: The layout is clear and simple to navigate. Even with all the features, it doesn't feel overwhelming.
* Versatility: I can use it on a variety of instruments and vocals, making it an invaluable tool for my entire mix.
How I use it:
* Vocals: I often use the P44 Magnum as the first plugin on my vocal tracks. The EQ helps me shape the vocal tone, the clipping tames the dynamics, and the saturation adds a bit of warmth and presence.
* Acoustic guitar: It works well for adding clarity and body to acoustic guitar recordings. A touch of clipping and some gentle EQ adjustments can make a big difference.
* Electric guitar: I've found it useful for shaping the tone of my electric guitar tracks, especially when I want a more polished and produced sound. The saturation can add some extra grit and character.
* Bass: The EQ and clipping sections are effective for tightening up bass lines and making them sit better in the mix.
* Mixing individual tracks and busses: I sometimes use it on individual tracks to quickly get a good starting point and sometimes even on sub-mixes (like drum busses) for overall tonal shaping.

I found this amazing piece of art on Who Is Alex Elliot’s YouTube channel and I am very impressed by the quality of this plug-in. You are able to make this sound as clean or as dirty as you want. This is a a must on bass, you can add just a bit of saturation and mix in the Oomph and Sweet knobs and can make any dull bass have some character and body in the mix. I’ve used this on drums, bass and even vocals.

Sometimes you are looking for a sound and you can't get it. None of the thousand tools in your hands seem to be able to achieve it but then you throw yourself towards a niche product, known by few, few like those who know what to use to get that sound and... Bingo, you find it!
This is what happened to me with the P44 Magnum by Pulsar Modular. Another example: a few days ago in my studio while with a new client of mine, I introduced the P44 Magnum taking a track already mastered by his previous engineer and acting only on OOMPH, POOMPH and SWEEET controls, my guest exclaimed: “Wow-wow-wow, unbelievable, I want this plugin on all my new tracks!"

I wasn't sure at first if this was going to be different enough from P42 to be worth it, but after using it awhile it definitely is. I especially love the clipper and mod circuit saturation. The only complaint I have if you can even call it one is the CPU usage with everything on. It sounds so good though that it's totally worth it. Haven't even mentioned the tone shaping options, which are unique from anything else I've heard. Overall wonderful plugin!

This has become a versatile and important part of my mixing tool kit. It has also largely taken the steam out of my exploration of DIY hardware summing or analog sweeteners. I use this largely on group busses, mix bus, and sometimes on individual channels to help sculpt not just the bottom and top, with the Oomph, Poomph and Sweet, but the sweet O2 control for dialing midrange presence or thickness. I also use the clipper quite a bit to delicately control peaks. It's a seemingly simple tool but for me has so many ways to respectfully shape whatever I'm working on, like most Pulsar tools, it will only get better as I learn more ways to coordinate all the controls available.

Yet another fantastic product from Pulsar. P44 Magnum is a great tone shaper and the clipper is the cherry on top. It works well on tracks or the two bus. Great sound without over complicating the gui. Like P42 Climax I love how quick you can dial this in and get that wow factor you miss when it's bypassed.

Awsome job guys.

I was not sure which to buy, the P42 or the P44, but I bought the P44 first.
The P44 is a clipper and the P42 is a saturator, not a successor, but they seem to have different roles.
I can't explain it well, but the sound change by the O2 knob is very good.

Expected a lightweight P42, got a brilliant companion.

Oomph and Poomph are great to add a bit of weight where you don't expect it. Try it on synth busses or anything else that feels too flat or digital.

Sweet is a one knob sweetener that does a multitude of things at once. I use it a little less than the other options because it uses quite a bit of CPU.

The clipper is the best hardware clipper on the market from what I've tried. Ziad has promised a soft clipper in the future, so I'm looking forward to that.

The saturation circuit is the same as P42 I'm fairly sure.

Overall, Oomph and Poomph alone are worth the admission price. Sweet is a useful counterpart for the high end. O2 breathes life into anything. The saturation is a nice bonus, especially if you don't own P42. But why the heck wouldn't you own P42?

Such a great little unit, it lives on my master bus both to tighten up the bottom end as well as breathe life into the top. I originally thought it was an either/or proposition with regard to the P42—which I already had—but in conjunction they are twin halves of a true sonic masterpiece. Well done, PM!

When the first iteration the 'Junior' was made available, I was expecting nothing more than a slimmed down version of the P42 Climax. From jump I was very excited to have totally underestimated the P44's differences and singular sound. All of the new tone shaping features have the typical Pulsar Modular responsiveness and euphonic color. I've used this on sources as varied as Hammond, vocals, guitars, snare, and piano tracks, in both the first 'preamp' position in the strip to last, using the clipper and tape-like finishing sheen that the P44 can add (thanks to the posts and presets from Gearspace for that).

Once again, Pulsar Modular proves that the quality of the code and quality of sound have resulted in an instant classic and proves that a born-digital plugin can be as good or better than analog gear and consistently superior to modeled/sampled digital versions of analog gear.

THANK YOU!
