MARC DANIEL NELSON SIGNATURE · P455 + P450

P455 MDN SIDECAR

Console summing, a tube line amp, a punchy stereo EQ, a custom 2-bus compressor and two converters. Marc's chain, in one plugin.

P455 captures the analog chain of Marc Daniel Nelson, a two-time Grammy and French Academy Award-nominated mixing engineer, producer and educator: the first eight buckets of the Record Plant Sausalito console as a summing mixer, his favorite tube line amp, the punchy stereo bus EQ, a compressor built for this workflow, and the character of his two mastering-grade converters, Willie and Atticus. P450 MDN EQ, the dedicated stepped 2-bus equalizer, is included.

So, what is the P455 exactly? After almost a year of development, Pulsar Modular and I designed what I’d consider the closest stereo channel plugin to emulate the characteristics of console summing, as well as being able to recreate the effect of pushing into a console. Pairing that with my favorite tube line amplifier, master stereo EQ, and light tasteful compression.

The frosting on the cake, and what I would call the magic of the P455, are the Analog-to-Digital conversion character settings – Willie and Atticus. The Willie setting is very punchy, open, and forward sounding. The Atticus setting is wide and magical sounding, with notes that seem to extend, and the stereo field gives a sense of holographic imagery.

Marc Daniel NelsonFrom the foreword of the P455 user guide

Every stage is a choice rather than a fixed setting: two summing widths, two converters, the line amp on or off, the EQ and the compressor in or out. The compressor listens to the raw input, so shaping the color never changes the gain reduction, and INPUT and BIAS run the transformer and line amp anywhere from cool and deep to hot and tight.

THE SIGNAL PATH, LEFT TO RIGHT
2 CH · 8 CH
A single stereo bus or an eight-channel board, four stereo stems. 2 CH is tighter, center-focused and grittier; 8 CH is wider and deeper with a relaxed center.

Marc's two converters, named after his dogs. Willie is tight, punchy, open and forward. Atticus is laid back, velvety and wide, with notes that extend.
LINE AMP
His tube, transformer and inductor line amp. On, the sound expands up, sideways and in depth; off, it is still in the path with the tubes cold.
THE COMPRESSOR
Built for this chain: auto attack and auto release you can nudge from FAST to SLOW, RATIO A at 1.2:1 or RATIO B at 1.8:1, an 80 Hz sidechain filter and a transformer output.

“No other plugin does this. The 455 sounds absolutely terrific. Just like the console in studio B at Record Plant, Sausalito. Spending a year recording Fleetwood Mac’s Rumours on that console, the sound is burned in my head forever and this is IT. The Eq section behaves just like what I remember. That soft saturation the more you push the eq. I have been waiting for years to have my old friend back.”

"I've known Marcus for a very very long time and have always respected his ears and meticulous approach to audio. So when he called to say he had some new plug-ins, I immediately had to hear them. I'm mid mix on an album and quickly added the MDN Sidecar to a percussion bus and was immediately impressed with the flexibility and sound. So yeah, that's staying. The MDN EQ was next and offered that familiar clarity and presence I'm accustomed to hearing from API. Kinda fat... kinda clear... guess that's staying, too. Obsessively summing through extensive analog chains, any plug-ins I use must compete with my racks of outboard gear or they never get used. Well, these new MDN "units" are definitely getting used. Great job!"

Let’s start with the EQ.
Having owned the analog version of this EQ, I was genuinely surprised at how good this emulation sounds. I often use just the EQ because of the way it effortlessly pushes certain elements forward in a mix—it has that unmistakable character.
But that’s only part of the story. The rest of this plugin is an absolute vibe machine. I’m usually not a preset person—they rarely fit the way I work—but these presets are among the best I’ve ever used. Drag, drop, and you’re in business.
This lives on my bass guitar chain—always. On drums, it’s disgustingly good as an insert to add punch or vibe, and it shines on parallel tracks when you really smash it. I’ve even used it subtly on a couple of masters that just needed a little extra character.
And to top it off, the CPU load is impressively light, so I can throw it on as many tracks as I want without worry.

This plugin really adds thickness to the sound.
The 8-channel summing creates a nice, wide image—especially when paired with the Wide control set to max. If you’re after a narrower sound, switching to 2-track summing and setting the Wide control to the middle position or off gives you great flexibility.
The API-style EQ and filters sound excellent, and it’s great to have them available separately in the P450 plugin for use on individual tracks.
The A/D converter, op-amp, and compressor all offer useful options for shaping the tone.
The Bias knob is especially handy for adjusting the overall character and intensity of the plugin’s effect.

Before this Plugin came out I was about to spend thousands of dollars on outboard gear just to get Analog Summing in my workflow.

After hearing how great the P455 was I decided to give it a try and I was not disappointed.

On top of sounding awesome and doing what exactly what I wanted you get the benefits of it being a plugin. Throw it all over your project, where two tracks or more are gathered, throw them through the Sidecar! It accomplishes what would be hours of work in the analog world, which allows way more time and freedom to experiment and make useful changes to your mix.

The Pulsar Modular P455 MDN Sidecar is a unique and inspiring summing plugin that can add a lot of analog gooey to your mixes. If you're a singer-songwriter guitarist looking to add some unique analog elements to your tracks, I highly recommend checking it out. It's a great tool for adding that extra something to your music and taking it beyond traditional mixing techniques. I predominantly use Sidecar for its 8-channel analog summing on the Main Bus for its sonic character and also stereo imaging capabilities.

Wow, this summing system plugin is not hype at all; it really does it.

I have been trying and using a lot of summing mixers over the years, and I know how summing sounds, The P455 shines as an individual "hardware type" summing mixer. I don't know how this has been done in software, but it really shockingly does it. Now, I can place this on a mix and stay ITB without the need of going out of the box for summing.
the EQ is wonderful. The compressor is GREAT—just that perfect glue, Magic. The Bias section—MAGIC.
Everything in there is so useful, fully packed with high-quality processing,

P455 Sidecar adds a little dimension as soon as you strap it across a buss. You can tweak a little or really dive in to sculpt the sound. From a workflow perspective it does the job of 4 or 5 plugins and allows you to move quickly through a mix.

I don't know the technical details, but this plug-in allows you to feel the characteristics of analog hardware.
I feel that the BIAS knob and the compressor section are especially good for the workflow of creating sounds.
The BIAS knob is not just a WET/DRY knob, and I get the impression that it can be used in conjunction with the Input knob to arbitrarily adjust the characteristics of the P455's analog hardware.
I appreciate the compressor section after making various adjustments.
There are many parameters that are not obvious at first sight, so I recommend reading the manual and doing a demo.
The manual also contains tips and tricks, which will be a good stimulus for your production.

After trying p455 on the 2 bus with the trial version, I had an epiphany. The mixdown already sounded great before, so I wasn’t trying to fix anything. Yet, when I started with the preset “sounds like a record” and did a few minor adjustments, it sounded bigger somehow. Width without messing up the midrange! Even subtle blending with parallel processing did a major shift in the warmth of the mix. You can do extreme things with this and you can also do minor adjustments. Either way, I will say I have no other plugins that will get me this particular “sound.” It’s a specific kind of sound and I dig it. Simultaneously softens some of the harshness that builds up over multiple tracks, yet can enable a velvet punchiness that breathes like an analog record often does. Thank you Marc and Ziad and the rest of Pulsar, these are great times to be a ITB producer/musician.

This plugin has the ability to add real analog dimension and depth to source material. I love it on subgroups and masterbus.

I have a multitude of plugins and I have become pretty adept at quite a few of them. I'm a composer/producer where sound and mix is as important to me as the musical composition. After demoing P455 Sidecar on a track that contained quite a bit of synthesized instruments, I was blown away with the sound on my mix bus. It was subtle but yet gave me "that" sound. The mix became balanced and present. I never had the pleasure of working on an API board (although I have many API plugin emulations), but if this software is anywhere close to that sound; I've missed out!
The concept behind this is brilliant. It is kind of a steep price, however, if your music is important to you, it is a rather small investment to your craft and possibly livelihood- no matter how many alternative processing plugins you own.

It's lovely. I wasn't sure if MDN's signature sound would work with my stuff (I do extreme metal - death metal, black metal, etc.) It does! I love the new features from the latest update.

First off, love MDN, he is such a great mixer and we’re so lucky to have his teachings available (for free) on YT…his lessons have done more for my mixes than any others! As soon as I heard about this, didn’t bother demoing, just pulled the trigger…it’s the least I could do to support someone who’s been so gracious in sharing his skills with us at no charge.

So far I’ve had the 455 on the 2bus, group busses and lead…killer in all instances! Also put the 450 on almost all tracks, loving it even when just using to HPF or LPF…really so great sounding. And the bias on both is incredibly handy! (Highly recommend reading the manual, so many good tips on using it.)

Honestly, I seriously would recommend this for plugin of the year, maybe the decade! This plugin removes the need for so many others and does it so well.

The only thing I’d like to see is the option to take the ADC out of the chain on the 455. I have a Burl ADC and would like to A/B this with and without it in the plug. Other than that, perfect…thanks Marc and Ziad, what a gem!

It feels awkward to use words like "delightful" to describe a plugin, but this one fits the bill. Every button or knob adds something, however subtle, to the audio you're applying it to, in a way that makes you smile a little. The sidecar sounds incredible, and offers endless tone shaping options, and the EQ, as simple as it is, always sounds pleasant, and adds something. It is seemingly impossible to make this sound bad.

The more I use this and become acclimated with the fine things it makes possible with sound, the more I see this as a "One small step for man, one giant leap..." kind of thing. I've said a few times that one plugin or another was my favorite of pick a year, but this - speaking only for myself and your mileage may vary - is changing how I feel about mixing. This plugin has affected me in a positive way more than any other plugin I have ever used.

I'm an old fart. But when I get in this sidecar I'm a kid again with the wind blowing through my hair, a big smile on my face, and bugs in my teeth. Mixing just became fun again.

When I bypass all the instances, my mix just loses "something" that I can't fully describe in words. It's like finding the missing piece of a jigsaw puzzle. Finally the picture is complete. Well done gentlemen.

I promised myself...no more plugins. And then you release this masterpiece. I have never heard such clarity and depth in audio. Each component of the mix remains separate and distinct while the mix itself remains in perfect balance. I have been searching for this elusive "glue" for decades and you have nailed it!
My Dad had an old tube Hi-Fi amplifier that he built. Its 3D sound and forward characteristics always sounded so much better than the current Hi-Fi amps that I grew up with. I thought I would never hear that wonderful sound again. P455 MDN Sidecar instantly brings back those fond memories of my dad's old tube amp.
