Creating Stutter and Glitch Effects using Sampler Loops in Reaktor

David Earl shows how to create glitch and stutter effects by navigating within sampler loops in Reaktor using a single math module! The results are both complex and fascinating!  

I was not the greatest math student growing up. Math was always intimidating and I often got poor grades. Once I got into synthesis, I realized with a quickness that I was going to have to overcome some of that insecurity. There is no better way than to make synths. The desire outweighed the fear, and away I went.

With a little simple math in Reaktor, we can achieve some pretty useful results. As we saw in the MPVHub article I wrote about harmonics, we were able to use some math modules to get the harmonic series. In this article, we are going to use only a singe math module: Multiply.

We will navigate a drum loop using two knobs that determine the Sample Start time, Loop Start Value, and Loop Length Value. 

Start with a new ensemble (File > New Ensemble) and open Structure view of the Default instrument.

Step 1:

Using Control-Click > Built-in Modules, create the following within the default instrument:

  • MIDI In > Notepitch
  • MIDI In > Gate
  • Sampler > Sampler Loop

Step 2:

Control-Click, and select Built-In Modules > Math > Multiply

Step 3: 

Control-Click on an input port of the Multiply Module, and create a control.

Step 4:

Control-click on the control attached to the Multiply module and select Properties. In the functions tab, give it the following values:

  • Max = 1
  • Min = 0
  • Num Steps = 
  • Mouse Resolution = 12

Great article David, thank you !
Hope to see more Reaktor tuts from you.
