Logic Tutorial: Granular Synthesis w/ Reaktor (1 of 2) Secret Knowledge w/ Shadetek Pt 8

Dubspot instructor and course designer Matt Shadetek returns with another episode of Secret Knowledge, a Logic Pro video tutorial series full of production tips, techniques, and advice for Logic users. In the first installment of this two-part video tutorial, Shadetek explores the concepts of resampling and granular synthesis using Logic Pro and Native Instruments’ Reaktor.

Resampling can be a creative way to create new parts which are texturally related to your original elements and feel like part of the same sound palette. In my previous video on creating resampled pads, we took a look at this concept using Logic’s EXS24 sampler and if you’re new to these ideas that’s a great place to start.

For this tutorial we’re going to get a little more adventurous and combine the technique of granular synthesis with resampling using the Reaktor instrument Travelizer. Granular synthesis is a process in which we take a sound and slice it into thousands of tiny pieces called grains, and then manipulate those grains by making choices about their duration and pitch as well as the order in which they are played. Using this technique, we can transform a standard sine wave-based synth line into a swirling cloud of sound.

Travelizer is one of the standard instruments which comes with Native Instruments’ Reaktor, and it allows us to do some serious processing on our original audio source using granular synthesis techniques. In this example we’re going to take a piece of our track, generate new sounds by running it through Travelizer and manipulating the controls, and then record those variations.

Because Travelizer has a number of controls and we want to improvise with many of them, we are going to avoid using automation because this might become cumbersome quickly. Instead we’re going to record our performance directly as audio by bussing the Reaktor signal to an audio track and recording it in real time.

In this first episode we’ll cover the basics of creating the audio files, setting up the routing and loading them into Reaktor. In part two we’ll explore the actual granular synthesis tools. – Matt Shadetek
