How to use compression in Reason

Propellerhead’s Reason is loaded with different compressors. But knowing which one to use, when, can be a bit tricky. And learning how to use a compressor is also hard. That’s why I’m here to show you about how to get the most out of each compressor to make your mixes sound great.


Also, check out this article if you're looking to understand more about how to use compression in general.

MClass Compressor

This is a great all around compressor with a straightforward design. It’s got a pretty fast attack (which is variable) with the ability to dial in a long release, plus the ability to select soft-knee compression. It also allows you to apply makeup gain.

This is the most surgical of the compressors in Reason, and is the one you should reach for if you really need to sculpt the envelope of a sound. The variable attack allows you to either clamp down on a signal hard or let most of the attack through. 

For smoother, more subtle effect, you can also enable the soft knee knob which will make the initial onset of the compressor less pronounced. Finally, it ability to adapt the release can help the compressor pump in time to the song more musically.

Not only is this a great surgical compressor, it’s also the number one tool in Reason for using side chain compression. Simply flip the rack over and insert a side chain key. 


You’re off to the races!

The Mixer Compressor

Every channel in Reason runs through the mixer, and every mixer channel includes a built in compressor (under the Dynamics section). While the Reason’s mixer compressor doesn’t allow as much control (you can’t dial in the attack speed, chose a soft kneed, or adapt the release), it sounds nice and gets the job done.

This is the compressor you want when you just need to tame the peaks a little bit. It’s a workhorse that shouldn’t be ignored when compression you tracks. It’s not particularly musical or precise, but that’s often not needed if you’re just looking for a couple of dB of compression

The Mix Bus Compressor

The grandad of Reason compressors! I use this on almost every song to really glue the mix together. The most important thing to note about this compressor is that EVERY channel flows through it, so a little bit goes a long way. 

Here’s how I use the mix bus compressor in Reason 99% of the time: set the ratio to 2, the attack to 30, and the release to Auto. From there, I dial in the threshold until it’s doing 2-3 dB of gain reduction on the peaks. Then I adjust the make up gain to compensate, usually setting it at 2-3dB. 


Now You Know How to Compress in Reason

There you go, you’ve learned how to get started using compression in Reason. With these tips, you’ll always be able to grab the right compressor for the job in Reason, and dial it in just so. 

There are a couple of other compressors in Reason as well, but they are much more specialized. Start out learning how to use these compressors, and once you feel comfortable with them, then you can start exploring!

Reason's stock compressors are pretty decent, but if you're looking to craft your mixes with even more control, add new layers of warmth and punch, then you may want to consider a few upgrades. That's why we've put together our review of the best compressor plugins available.

From a Frustrated Producer in a Ragtag Bedroom Studio to Major Placements on TV Earning $1,000s!


My name is Evan, and I've been making music since around 3rd grade. I'm from San Diego, California, but I've lived in Washington, DC for the last 20 years.

After 3 grueling years of grad school, though I had put aside serious attempts at making music. I found myself spending my days doing work that was dreadfully uncreative, with a ton of student student loan debt.
Which made me feel like my favorite parts of myself were withering.
But I didn't know what to do about it.
Being in my early 30s with tons of student loan debt, in a world where there is "no money in music," I felt like my youthful dreams of trying to "make it big" were dead. Like my music would remain unheard in my head and hard drive. 
Frustrated by my inability to get my music heard, I started researching solutions.
Instead, I wanted to find a way where I could focus on making the music and let someone else deal with promoting it. 
I realized the music licensing was the perfect opportunity for a solo artist like me to get my music heard, without having to do any promotion. I just need to focus on improving what I could control - my songwriting and my production skills.

While I still have a full-time day job, I have created systems that have allowed me to produce dozens of songs a year in my spare time.

My songs have been on Netflix, TV shows like the 90 Day Fiance, an award-winning indie film, and NPR’s “All Thing Considered.” They've also been streamed millions of times.

In addition to being a music producer, I am passionate about teaching people how they can make professional-sounding music and earn money licensing it, all in their spare time.

Thousands of musicians, like yourself, have trusted me to guide their musical journey. My YouTube videos have been watched nearly a million times. And my story has been in Forbes, Side Hustle Nation, and the Side Hustle School.
