Complete Guide on How to Chop Samples in Reason DAW


Anyone can learn how to chop samples in the Reason DAW. There are at least four different ways to chop samples in Reason, and each of them has their own pros and cons.

Update (2/2/18): These days I’m pretty much exclusively using Serrato Sample (affiliate link) to chop samples. It is like the future of sampling. It makes chopping so fast and easy! Much better than any of the methods described below, but it costs $99. 

You can use the sequencer, Kong, Dr. OctoRex, NN19 or the NN-XT.  This article will tell you how to chop hip hop vocals in Reason and explore when you may want to use each of the devices.

And if you’re looking for a good source of vocal samples for Reason to chop, I’d recommend Loopmasters (affiliate link). I get most of my samples from their massive library.

How to chop samples in Reason with the Sequencer

Reason 9 added a bunch of new features to the sequencer that may make the Reason 9 sequencer the most powerful sequencer in the Reason DAW workspace.

As far as I'm concerned, it added the best way to chop samples in Reason, which you can see how to do here. Basically, you can create your own Rex loops in the sequencer in just a couple clicks, then use Dr. OctoRex to chop them up!

The huge benefits of using the sequencer – unlike Kong, NN19, and the NN-XT – are that you can time stretch a sample without affecting the pitch. And you can change the key of the sample without affecting the tempo.

These two features are huge.

Here’s an in-depth video tutorial on using Propellerhead’s Reason sequencer to chop samples.

But wait, there’s more….

Using Reason’s sequencer, you can easily edit the pitch of individual notes and move the time of transients. You also have access to the formant control to create unique effects.

And it also makes it really easy to cut tails, mute small sections and re-arrange fragments.

The downside to chopping samples in Reason’s sequencer is that it’s not very creative.

When you use Reason’s sequencer to chop samples, you’re not going to be able to use a keyboard. Instead you need to hunt through your sample library and place the samples you want directly on the sequencer timeline to use them.

As a result, it doesn’t lead to nearly as many happy accidents as the other methods, and can be quite time consuming.

How to Chop Samples in Reason with the Kong

The Kong is my preferred way of chopping samples in Reason. To me it feels the most natural and musical, like old school hip hop chops.

Aside from feeling highly musical, chopping samples with Kong has a few other benefits. You can use the pad groups to create mute and choke groups, easily set up round robins, and get easy access to certain effects only available in Kong (there’s a workaround for this, though).

Here’s an in depth video on chopping vocal samples in Kong.

The big downside to the Kong (aside from the pitch and timing issues mentioned above), is that it’s a bit of a pain to actually set the sample start and end point.

Chopping Samples in Reason Using Dr. Octo-Rex

Dr. Octo-Rex is probably my favorite way of chopping samples in Reason. It makes it really easy to pick slices, apply the most typical types of filtering, and loop things, if necessary.

You can easily make quick changes to the sound of individual slices, like reversing them, changing the pitch, or volume. However, it’s not that easy to move the location of the slices. You’ve basically got to convert the loop to an audio track, then move around the slice points. Then reconvert to Rex. The video details this more.

But yea, moving slices in Dr. Octo-Rex ain’t the easiest.

How to Chop Samples in Reason Using the NN-XT

Reason’s NN-XT Sampler is a super powered tool for creating complicated layers of sampled sound. Learning how to chop samples in Reason using the NN-XT is very similar to chopping samples in the Kong. In fact, the sampler used in Kong is just a striped down version of the NN-XT sampler. So if you understand the basics of setting the stop and start times from the Kong video, you’re off to a good start.

When you first create an NN-XT, you’ll want to right click on the interface and select “Reset Device.” This will clear out the current samples. From there, you want to click on the tab to expand the NN-XT’s “remote editor” and click on the file icon to load up your sample.

When sampling in Reason’s NN-XT, you can easily layer multiple samples. You can also chromatically map the samples  across the keyboard, or just assign them to one note each. Please note that when chopping samples in the NN-XT, changing the pitch will effect the speed of the sample. Sometimes this creates cool effects, so experiment with it.

The NN-XT also provides a ton of tools for modify the pitch, amplitude, filtering, and velocity, among other things, of each sample. When used well, these additional tools can add a lot to a performance. However, if you don’t need the full flexibility these tools provide, it is often simpler to chop samples in Reason using the NN-19 or the sequencer.

And, of course, here is a detailed video on how to do it.

Chopping Samples in Reason Using the NN-19

The NN-19 is really just a stripped down version of the NN-XT. It’s easier and faster to load samples in the NN-19, and it provides a little less strain on your CPU.

The cost is that you have fewer filtering and modulation options, and layering samples isn’t nearly as powerful.

But if you are perfectly content with the sample you’ve got, there’s no need to use the more complex NN-XT, and this is probably the most light weight way how to chop samples in Reason.


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‚Äôs ‚ÄúAll Thing Considered.‚ÄĚ 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.
