  1. 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.

  2. 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. Getting that center back by turning off the Stage Focus is perfect for my taste. This plugin has ended my hunt for some ITB analog mojo. The standalone EQ is a huge bonus. Using it on snare and vocals is a lot of fun.

  3. Not only is this an outstanding plug-in in terms of its feature set, versatility, ease-of-use, and outstanding GUI – but the developer has also actively listened to user feedback and attempted to implement features that reflect how the user base is using and responding to this plugin. My first Pulsar Modular purchase – definitely not my last!

  4. Absolutely killer. The first plugin I’ve heard that’s got the API comp right – organic, punchy low end weight for days. Really impressive work – highly recommended.

  5. 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!
