I own and use UAD tape emulations (Studer & ATR-102), but didn't gel with Arturia's J37 emulation, despite liking their Tape Mello. I rate Softube Tape, was a healthy upgrade from Waves' J37 and Kramer tape emulations. There are many others I have not tried, but I am confident that the P821 will blow them out of the water much like it does with the above I mentioned. I spent a good month testing this out across various mixes, before purchasing. It's a superb sounding plugin and absolute diamond for mixing and mastering. Looking forward to deep diving other plugins by Pulsar.
P821 MDN TAPE
The Stephens 821, the machine behind Rumours, Aja and The Wall.
Modeled on Marc Daniel Nelson's personal Stephens 821 2" tape machine. Transformerless, with no capstan and no pinch roller, its free-moving tape path gives a massive, open soundstage with no aggressive clamping. The first plugin of its kind where you are actually hearing tape, and how it reacts.

The machine, not a snapshot of it.
“After nearly two years of development, Pulsar Modular and I designed what I’d consider the closest emulation of an analog tape machine on the market. The Stephens 821’s massive, expansive soundstage, a result of its minimal electronics and transformerless design, is perfectly captured in this plugin. With no aggressive compression or clamping down, this is the first plugin of its kind where you’re truly hearing how tape reacts. Pure size for miles.”
Marc Daniel Nelson, foreword of the P821 user guide
Three controls set the tone: Tape Formula, Tape Speed and INPUT. 456 saturates sooner, with richer harmonics and earlier compression; 900 takes more drive, with more headroom and lower noise. 15 ips adds the low bump around 20 to 25 Hz and softens the top; 30 ips tightens the lows, extends the highs and leaves more room before saturation. Raise INPUT until the loud passages read around 0 VU, −18 dBFS RMS, and from there every dB brings more density, gentle compression and rounder transients. THRU keeps the 821 electronics and their openness without the tape compression, a second color rather than a bypass.
The rest of the deck refines it. LO and HI bias voice the tape itself and react to how hard it is driven; the LO and HI shelves sit PRE, where a boost drives the tape harder in that band, or POST, where they shape the result cleanly. HISS is a texture that settles to a stable floor instead of building up in the delay. WOW and FLUTTER add the motion of a real transport, Slow for a well-kept machine and Fast for swings up to ±124 cents, and the same motion drives the 1 ms comb of the flanger. The tape delay takes its time from the delay speed and OFFSET, 62.5 to 350 ms, with a feedback that never runs away. Stage Focus fits the wide 821 image to the mix, and CENTER locks the low end to mono while the sides stay open.
- TAPE · THRU
- TAPE runs the audio through the modeled transport: saturation, gentle compression, rounder transients, glue. THRU keeps the 821 electronics and their openness without the tape compression, a second color rather than a bypass.
- BIAS · SHELVES
- LO and HI bias, ±10 each, voice the tape itself and react to drive: a bass shelf hinged around 50 to 100 Hz and a treble tilt around 1 to 2 kHz. The LO and HI shelves, ±10 each, sit PRE to drive the tape harder in a band or POST to shape the result cleanly.
- HISS · MODULATION · DELAY
- A true hiss generator with a stable floor and Hiss Dim for the silences. WOW around 1.9 Hz and FLUTTER with Slow and Fast, the same motion driving the flanger. Tape delay from 62.5 to 350 ms by speed and OFFSET, feedback without self-oscillation, HPF and LPF on the repeats only. LO-FI with the RANGE voiced together with MAS.
- STAGE FOCUS · CENTER
- Full, Half or Off fits the 821 image to a mix; CENTER pulls the low end to near-mono, about 5 percent side energy, while the mids and highs stay wide. Metering: dual-needle VU, dBFS or dBU theme, −18 dBFS RMS around 0 VU.
From the pros who know this machine.
“There's a lot of plugins that come close. There's a lot of things that get us nearly there, but this is the first time that I feel like the soul of tape is represented in a plugin. No other tape plugin has come close to this. The P821 MDN Tape is really remarkable.”
“The Stephens 821 is the best-sounding tape machine ever made, and the P821 MDN Tape is the best tape machine in a plugin and unlike anything out there by far. It was a joy to hear this plugin doing the scientific process as it was designed. What more is there to say? It's that good. No need to hype with silly marketing; just listen to it.”
“I know this machine well, as I used it to record and mix Fleetwood Mac's Rumours album at the old Producer's Workshop. Finally a tape emulation that doesn't sound like a mess. Reminds me of that beautiful sound of the original Stephens tape machine. That thing made me sound like a genius and the plugin is just incredible.”
“Not only is the P821 MDN my new favorite analog tape plug-in, it's also my new favorite lo-fi, flange, and slap delay effect, all with an intuitive user interface and great graphical feedback. I find myself using it as much for the lo-fi, flange, and delay as I do for the tape saturation, which itself adds a wonderful, glued finish to my mix and gives me that glorious 15 ips low end bump if I need it. Marc has done it again, giving us engineers another great tool to elevate our mixes and our creativity.”
“I used to own the actual Stephens 821 deck used to create the P821 MDN Tape plugin and agree it was the best-sounding tape machine ever made. The P821 sounds amazing and adds an analog quality I have never gotten with any other plugin.”
“Wow! Pro Tools at 96k, it sounds as transparent and huge as I remember hearing from the wonderful Stephens in Armin Steiner's Sound Labs mix room. It is utterly amazing to hear a plugin take me back to that experience.”
“I had a chance to try out the P821 plugin and it was fantastic! It really opened up the mix in a crazy way. I was expecting your standard tape plugin thing, but it is totally its own thing. My mix sounds bigger and with more depth than before, but without any tonal change. The P821 MDN Tape really blew me away. It feels like you're actually working with tape: huge sound, tons of depth, and it reacts to input in a way that's super organic. It's the closest I've heard. It's now a go-to in my mixes, and I can already tell it'll be a part of my sound moving forward.”
“This sounds insane! If you want to make a sound come to life, use the P821 MDN plugin. Effortless magic. Marc did it again!”
“I put this on a kick drum and instantly was like, what the hell! The low end dropped way lower but got way more clear. How on earth did you do this? This on background vocals too is just dope. This plugin sounds incredible.”
“This new Pulsar Modular P821 Tape plugin is absolutely magic. I have had the pleasure and privilege of working on several Stephens tape machines, and the 821 MDN is the best representation of tape I have ever heard.”
“When I tell you that the P821 MDN tape machine plug-in offers the very best 456 emulation in the game and instant access to authentic creamy tape flange, it's because I heard it for myself in the first 5 minutes. We all know that tape machine plug-ins offer the illusion of access to the imperfect world of analog colors that paint the audio pictures we love, but some are better than others and this one rises above. You will see for yourself that the P821 MDN delivers on everything we all love about tape: transient control, saturation, modulation, delays and tonal character. Run to test it on individual tracks, groups and your final master.”

What owners say.
Aside from a very select few tape emulations, I always felt like most were just compression/EQ/saturation. MDN Tape is different — 3D, with a real low-end bump and, dare I say, "analog" sound and feel. The video from MDN intrigued me. The demo sold me on it. It will for sure live on my 2-bus from now on. Thank you, Pulsar Modular, for another great win for in-the-box mixing. Try it. Just try it...
True masterpice!! amazing sound
A masterpiece!
I have no idea how Pulsar Modular managed to create a plugin that extends the low end like this—but they did! Truly outstanding, with amazing creative possibilities when you start experimenting. A mega plugin!
Highly usable, very responsive, quite versatile, and above all: weighty, characterful-sounding tape saturation. Bonus points from me for the linkable input-output, useful modulation, and being extremely light on the CPU!
Best tape plugin to date in my opinion. Does wonders on drum tracks and busses. Doesn’t always work on the mixbuss for me, but when it does, it’s really special. You can look at the meter, but I suggest tuning the input on linked mode by ear. The bias control on lows and highs makes it really versatile, and I love the tape delay option.
Another winner from Ziad and Marc. It is nice to have additional features such as hiss, flange, modulation and delay. Love the sound. I have other tape emulations, yet this one will certainly get a lot of use. I love the sounds I'm getting. Nice combo with P455.
Giving mixes a special touch...
Both Pulsar Modular MDN plugins are truly amazing
Loving this on master bus! I actually use this in conjunction with Slate's VTM, relying on the P821 for wow/flutter. This plugin works as a tone-box, sporting a "lo-fi" mode that is very nice and even a flanger! The one thing I wish it had was a stop/play button for funsies!
I put this on a piano track and got a really sweet lo-fi nostalgic retro feel. Give it a try!
I’ve owned nearly every tape plugin on the market—tape emulations were my main obsession for years. By 2022, I finally gave in and went fully analog, and for the first time, that craving felt satisfied. Since then, I haven’t touched a new tape plugin… until now.
I can’t fully explain what MDN Tape is doing under the hood—just like I’ve never completely understood what makes analog tape sims tick—but this one feels right. It has that elusive quality that works on almost anything you throw at it. Also... How the hell does it sound this good AND be so CPU friendly.
Honestly not just "another tape" plug-in at all... a great emulation of a unique machine that really gets to the essence of what tape does and isn't just a glorified pre-amp emulation. Also. a wildly under appreciated FX/vibe box with its creative controls at the bottom. My favorite thing might be what it does to bass/sub energy, placing it "outside" or "around" the speaker while keeping it punching like no other ruin of the mill stereo image tool does, sometimes I use it just for that aspect. If you think you already have this in your arsenal, you don't.
Excellent for a digital summing effect and excitement.
It’s become my new favorite tape flavor. It’s getting used all over my projects.
Absolutely incredible. I’ve rarely had a true “wow” moment with a plugin, but this one hit me harder than any other. The sound it delivers is unmatched — the sense of depth and width is stunning. Everything becomes richer and more alive, and when you bypass it, the mix suddenly feels plastic and artificial by comparison.
Give P821 MDN Tape a shot on your master bus once and it instantly reveals itself to be something quite special indeed, the only tape emulation out there that really focuses on injecting that special ethereal tape quality instead of stopping at just some harmonics and modulation. This will be living on almost all of my mixes going forward.
Really nice tape emulation. I'm enjoying using it a lot all across my mixes. I work mainly with acoustic instruments and vocals, and I find that this plugin is very well suited to this type of music.
I already had some excellent tape plug-ins. And again, this one is different. I especially like how it brings out these little subtleties and details which you would barely notice when it's off. I highly recommend checking it out. You wouldn't want to miss out.
Excellent tape simulation plugin, unlike any other, tight bass and instant 3D effect.
Really like the ”life” this plugin brings to the mix when mixing into it on the mixbus.
So far it seems like 456 and 15” is my favorite for this effect. Center image button on and the spread-button on max.
Haven’t been able to reach that depth and space with other plugins.
It can also do great things on buses and on f.ex snare.
But bringing it on everything seems making it easy to go over board with it.
Exellent!!!!!
I've been using this quite a lot and loving the results. Part of my channel strip from here on..
Great tape plugin, gives a holographic depth to vocals I've not heard a plugin do before. I'm not familiar with the hardware, but it's doing the same sort of thing to the depth on vocals that can be heard on I Love You by Eddie Holman.
This thing is phat! I like the bottom, glue, and width P821 imparts on the mix bus (15fps 456). The width button seems to work for me with this one, not so with the P455.
This is an amazing plugin! It has something different from all the other tape plugins I've used so far.
Love what this does on drums or a guitar bus. Subtle but really does a unique thing that you aren't going to get out of your other tape emulation plugins.
Have been demoing this thing for bout a week now...It's special! Absolutely reminiscent of tape like I remember. I have most other tape emulation plugs and this one REALLY does the "thing"! Well done!
I demoed this and thought it was a good plugin. But! Then watched the Clay Blair video and immediately got a better understanding of what and how to use the P821. Went from good to Awesome. I highly recommend watching his video. GREAT Plugin as Always
I demo this plugin for one day and purchased it in the next day. My ears told me this is what I want for a longtime.
I agree with a previous reviewer on this one- Mr. Nelson and Pulsar Modular have really done something special with this one AGAIN. A/B with UAD Ampex-102 and thank me later...
This is the first tape emulation what I really hear and FEEL like real tape and I tried all of them. I hope it will be on sale soon because the price is too much for me. Thanks
I LOVE the imaging quality that this provides. It has an innate ability to place everything in its own space in the stereo field. It also makes the transition between low end to high end a seamless and cohesive through its saturation!
I A/B'd this with UAD's ATR-102 and this sounds way better. I was surprised.
I should have added that it is utterly amazing to hear a plugin take me back to that experience.
Awesome legendary Stephens Electronics 821 emulation!!!
I would use it when I want the texture of a late 70's hi-fi sound that's not dirty tape sound.
