Delay Effect - Cross Feedback and Style
Understanding and manipulating crossfeed and style algorithms for the delay effect so as to create huge sound scapes.
Stereo delay effects come in all shapes and sizes and with feature sets that are nothing short of astounding. Gone are the days of simple feed delay processors that offer basic filtering and timing control over the left and right delay lines (channels). Nowadays, delay effects processors come with a well specified and detailed modulation matrix, tons of filtering tools, acres of editing possibilities and incredible control over how each delay line behaves.
Before we start exploring the power of the Style and Cross-Feedback features of a stereo delay processor let us ground ourselves in the workings of a delay processor. This FREE video tutorial explains how a delay effect processor works: Delay Effect – what is it and how does it work
Cross – Feedback
When a signal coming out of a delay line is routed back into the other delay line this is called cross – feedback. Cross-feedback is used specifically when using stereo delays and allows different delay times to be mixed together to create incredible sonic scapes. When coupled with the modulation matrix this single feature takes sound design possibilities to a whole new level. It really is a shame that more processors don’t afford this feature. The ability to feed one channel to another and then have control over that process opens up a world of sound design opportunities.
The Style function is available on a number of modern day processors. It is not exclusive to delay effect processors. Style simply refers to a custom shape/response or process that is used to further shape a sound. Common style processes can encompass something as simple as an EQ response or something far more complex like an emulation of a valve stage. It is, in effect, a template that can be edited for different purposes. The thinking behind offering Style modes or options is that the user is then afforded another level of processing separate to the process being used. For example, you might have created a wonderful delay effect but now need to feed that delay effect into a tape machine or a telephone or a broken amplifier…….the delay effect processor that offers Styles will accommodate all of these processes and much much more. Soundtoys Echoboy is an example of a well thought out and detailed delay effects processor and it comes with page after page of Style settings that can be used to further shape and colour the delay effect.
In the video I show you how to use Softube’s Timeless 2, Izotope’s DDLY and Soundtoys Echoboy stereo delay effects plugins. I explain how to use the Style function on Echoboy, the analogue and grain functioons of the DDLY and the Cross-feedback feature on Timeless 2. I run through many sound design examples using a female vocal recording and show you how easy it is to create different textures using these essential features.
