Lewitt Space Replicator Year End Sale (~50% off, until 4 Jan)

Hi! This is Jooyoung Kim, a mixing engineer and music producer. Today, I’ll introduce a room/headphone simulator, Space Replicator made by Lewitt.

I received the NFR code for this product from Plugin Boutique for this review, and if you purchase the plugin using the links included in this article, I’ll earn a small commission that helps me keep going…!

Let’s start!

Space Replicator is a plugin that uses HRTF (Head-Related Transfer Function) modeling to allow you to experience sound with a sense of spatial depth, making it sound like real acoustic space when listening through headphones or earphones.

While there are indeed several plugins offering similar virtual monitoring functions, and some competitors boast larger headphone/earphone catalogs, Space Replicator’s distinct advantage lies in its specialized focus on HRTF and the process of creating personalized binaural profiles.

If you select a headphone or earphone model that you own and that is supported by LEWITT, you can generate a personalized binaural profile through a few simple steps. Although the results may not be perfectly precise, the effect was noticeably effective when I tested it.

Furthermore, the plugin features 12 different virtual spaces, each offering various listening perspectives or speaker options, and it also provides 6 different headphone simulations.

My favorite virtual space is the Vienna Synchron Stage A, which accurately provides the acoustics of far-field speakers. Since small studio producers and engineers usually can’t access such a setup—and neither can I—this particular feature offers me a tremendous amount of practical things.

It is currently 50% off until January 4, 2026. Therefore, if you work in a space with acoustic limitations, I highly recommend this plugin.

That’s all for today. See you in the next post!

Black Friday Sale Summary: 2025 Virtual Instruments & Mixing Plugins

Hi! This is Jooyoung Kim, a mixing engineer and music producer. Black Friday is right around the corner, so, as I did last year, I’ll summarize all the plugin sales that I want to recommend for composing, mixing, and mastering music.

This post is not sponsored by any of the plugin companies listed. However, I have an affiliate partnership with Plugin Boutique, so, I’ll provide their purchase links alongside my explanations for any plugins they offer. Furthermore, purchasing through the provided link earns me a small commission that helps support this content..^^ (It’s really hard to make a living these days…haha..)

Then… Let’s start!


1) WAVES

I always recommend plugins made by waves to people around me. While their update plan policy is incredibly frustrating, it certainly doesn’t detract from the quality of their plugins. Additionally, they usually offer significant discounts during the Black Friday season.

I highly recommend the Horizon Bundle. This bundle features 93 plugins, all of which are highly versatile. The price is only $219(Tax Included), leaving no reason not to recommend it.

Specifically, the CLA series, the Renaissance Compressor, and the H-Delay are my favorites.

2) UAD (Universal Audio Digital)

Universal Audio has lots of useful plugins too. The LA-2A series, the 1176 series and the chamber reverbs are definitely my go-to plugins from UAD.

I own quite a few UAD plugins, and they were really expensive before Universal Audio launched the native versions. Additionally, the 10-plugin bundle was also very pricey, if I recall correctly. However, for this Black Friday sale, you can get 10 plugins for only $108.90 (Tax Included). I must admit, I find that a little unfair….^^. It’s a really great deal, so I highly recommend grabbing this opportunity.

If you haven’t had any experience with UAD plugins, I will select my top 10 recommended plugins for you.

  1. Teletronix LA-2A Leveler Collection
  2. 1176 Classic Limiter Collection
  3. API 2500 Bus Compressor
  4. Teletronix LA-3A Classic Audio Leveler
  5. EMT 250 Classic Electronic Reverb
  6. Fairchild Tube Limiter Collection
  7. Pultec Passive EQ Collection
  8. UAD Sound City Studios
  9. Hitsville Reverb Chambers
  10. Lexicon 224 Digital Reverb

3) IK Multimedia

Unfortunately, IK Multimedia already concluded its “Group Buy” event last month, so it is unlikely there will be any additional sales during Black Friday. However, I have written about IK Multimedia’s virtual instruments and mixing plugins previously, so, if you have an interest in this company, please read this article.

4) Arturia

Arturia offers a wide range of virtual instruments and mixing plugins. They boast significantly high quality, tthe only drawback is their high CPU usage. However, as CPU processing speeds have grown rapidly, I believe this is no longer a critical issue.

The price of the V collection 11 is $383.90 (Tax Included), and the FX Collection 5 is $273.90 (Tax Included).

I have written reviews before, if you have an interest, please read these articles.

5) Brainworx

Brainworx was founded by Dirk Ulrich, the same individual who established Plugin Alliance. They offer superb mixing plugins with remarkably good quality. They are also remarkably affordable, so you should definitely consider purchasing their plugins if you have a limited budget.

Specifically, I recommend the digital EQ, the bx_digital V3, from Brainworx. At just $11 (including tax), it is incredibly useful for identifying the frequencies where resonances occur.

6) Celemony -Melodyne

I currently use three main pitch correction plugins: Auto-Tune, Melodyne, and Revoice Pro. However, I find Melodyne to be the most intuitive plugin. I use it on almost every project.

The Studio version is now $301.40 (Tax Included).

7) Native Instruments

Native Instruments sells a lot of virtual instruments. Their Komplete bundle is their most famous, and it features a 50% upgrade discount during Black Friday.

8) Cableguys

I think you need Cableguys’ plugins if you want to create a modern-sounding track. Recently, many producers and composers are making the source audio groovy, and these grooves are created through artificial manipulation.

Cableguys’ plugins are made for these purposes.

I recommend Shaper Box 3 (at $97.90 including tax). Also if your budget is larger, the Cableguys bundle (at $163.90 including tax) is a great choice.

9) Eventide

Eventide’s reverb plugins are truly irreplaceable. The Blackhole reverb and the ShimmerVerb reverb are strongly recommended.

10) BFD Drums

I love the BFD drum plugin. My main drum VST is BFD, and their sounds are exceptional. While it has a steep learning curve, once you understand its complexities, it will provide truly realistic drum sounds.

The drum sounds on this song were created using BFD drums.

The basic components are quite good, but I highly recommend buying the London Sessions expansion pack.

BFD 3.5 is currently only $42.90 (tax included), and the expansion pack is only $20.90 (tax included). I strongly recommend these two products.

11) iZotope

iZotope offers famous plugins like the RX and Ozone series. They also have excellent reverb plugins. Currently, they are offering a 40% discount on their bundle upgrades.

12) Plugin Alliance

Since a certain point, Plugin Alliance began including tax when they sell their products to international customers on their website. Therefore, there is no compelling reason to buy their plugins directly from their website. You can earn points and free plugins when you purchase plugins through Plugin Boutique. Thus, I highly recommend purchasing them there instead.

My favorites include the Maag EQ4, the SPL series, and the Bettermaker C502V plugins.


I believe that covers all the main recommendations. There are still a few plugins I would like to recommend, but they are either not currently on sale or have fully transitioned to subscription models (like Musio 1).

Honestly, these days, I feel that plugins are not the most crucial factor in music production. The ideas and concepts are the most important aspects. Sound design and engineering are just the finishing touches to the music.

So, if you want to make meaningful music, I would advise against spending a lot of money on plugins you might use in the future. Just buy what you need now.

Then.. have a nice Black Friday season!

Cableguys’ Snapback Introduction Sale (~Dec 2, $29)

Hi! This is Jooyoung Kim, a mixing engineer and music producer.

Long time no post…!

I was too busy studying English and doing other work. Unfortunately, I failed to achieve the score that I wanted on the TOEFL test. My plan was to apply to a Ph.D. program this year, but I may have overestimated my English ability…T.T..

But I think it is reasonable for graduate schools to have a high TOEFL score threshold. If someone studies in Korea, I think they may have a good command of Korean and need to be proficient in the language. From the opposite perspective, English speakers will think the same way.

So.. I have to study English harder than before..

By the way, today, I’ll introduce Cableguys’ new plugin, Snapback. (The plugin was provided by Plugin Boutique, and if you purchase by the links, I’ll get small commission from them.)

It’s a simple audio layering plugin. However, this plugin has great detection ability and adds many flavors to the sources.

It analyzes the input signal in real time, detects each transient with high precision, and triggers two types of layers: a pre-transient “Snapback” layer and a main transient layer. This allows users to enrich kicks, snares, claps, and percussive sounds without manually adjusting timing in the DAW.

By automating phase-accurate alignment and offering detailed controls such as pitch, timing shift, stereo width, filtering, and dynamics, Snapback makes drum enhancement faster and more musical than traditional manual layering.

Let’s find out more about it’s parameters.

In the analyzer, a blue audio signal appears in front of the main source, with a purple audio signal behind the blue signal. The blue one is ‘snapback’, and the purple one is ‘transient’. They can be adjusted using the parameters at the bottom of the plugin.

I presume that many people are already familiar with the attack, decay, pitch, and all related parameters. Thus I’ll not elaborate about whole things. However, shift parameters refer to ‘shift timing,’ which can be adjusted from -4 ms to 4 ms. Width can be adjusted from 0% to 200%, and dynamics from 0% to 100%. HP and LP means High pass and Low pass filter.

Snapback and transient presets are organized into several stylistic groups, each designed to emphasize a specific aspect of drum layering. So, you can instantly hear how different combinations affect the groove.

Overall, Snapback is a simple tool, but it solves one of the most time-consuming tasks in modern production: clean and precise drum layering.

Its transient detection, timing accuracy, and flexible controls make it a fast and musical solution for enhancing percussion in any genre. I think $29 is really affordable!

That’s all for today. See you in next post!

XLN Audio RC-20 Retro Color Flash Sale! (~Oct 11, 60% Off)

Hello! This is Jooyoung Kim, a mixing engineer and music producer.

I’m excited to share that XLN Audio’s RC-20 Retro Color—the creative effect plugin famous for adding that authentic ‘Retro’ coloration to your sound—is having a flash sale this weekend!

I’ve received a Not-For-Resale (NFR) license to produce a thorough review for you. And if you decide to pick up the plugin using the links I provide, I’ll earn a small commission—Honestly, that small commission is a monumental help in keeping my work going and putting food on the table…:) Your support means the world to me.

Let’s start!


RC-20 Retro Color

RC-20 Retro Color has earned its place as one of the true ‘modern classic’ coloration plugins. Despite having been released nearly a decade ago, it remains incredibly popular, with producers all over the world still loving it. It has definitely become a steady seller in the world of creative effects.

These are the six distinct effects modules that make up RC-20’s sound design capabilities:

  1. Noise: This generator adds texture by letting you select various noise types (like vinyl crackle or tape hiss) and allows the noise level to follow the amplitude of the source material (using the Follow parameter).
  2. Wobble & Flutter: Use this to introduce the pitch inconsistencies associated with unstable analog playback (like a worn cassette or vinyl). You can also expand the effect from mono to stereo width.
  3. Distortion: This module is straightforward—it makes things sound distorted, offering a range of saturation from subtle warmth to heavy fuzz.
  4. Digital: Degrade the audio to recreate the sound of vintage digital gear by lessening the sample rate or bit depth to provoke that classic digital noise and artifacting.
  5. Space (Reverb): Simply put, this is a reverb module for adding depth and dimension.
  6. Magnetic (Volume Drops): This simulates the wear, flutter, and volume loss artifacts associated with magnetic tape recording and playback.

You also get helpful visual scopes that show you exactly how each effect module is transforming your sound in real-time.

To manage the overall vintage intensity, simply use the Magnitude fader, which controls total amount of the effects.

Finally, the bottom of the plugin offers essential final controls, letting you adjust the Input/Output Gain and apply a crucial EQ filter to shape the final tone of your colored sound.


Final Thought

Really simple, isn’t it?

The core effects are incredibly powerful, yet the parameters are streamlined and intuitive. With a plugin this effective and this easy to use, there’s truly no reason not to add it to your collection!

I especially recommend it for sound designers who frequently work on music for advertisements, as well as music producers of all genres. You’ll be able to inject a huge range of interesting and fun effects into your tracks. I think it would be particularly cool for adding grit and vibe to Rock vocals, and it’s already a staple in the production of Lo-fi music.
