Gating, as an audio effect, has been around for a quite some time. It is a really simple process which, when used properly, produces great results. Audio gating controls when and to what degree audio passes through a channel. Moreover, it’s based on factors including the signal level strength. In some cases, it’s referred to as a noise gate. Additionally, It can be used for a number of processes like reduction of unwanted external sounds, reduction of natural channel noise or to use it as an effect.

In past 2 decades, many gating effects were introduced. However, recently I came across a software plugin that essentially functions as a gating effect but besides that, it offers so much more. This effect is called “Gatekeeper” and it has been designed by PsyTrance veterans Infected Mushroom in collaboration with Polyverse music. In the next tutorial, I will go thru its main functionalities and give you some examples of what this plugin is capable of.

 

Let’s start gating 



Firstly, I have made a short pattern in SoundBridge which containing some basic elements like a kick drum, bassline, rhythm and couple of layered synth sequences. Let’s hear how it sounds.

Gatekeeper is a volume modulation plugin capable of pseudo-sidechain, compression, MIDI gating or LFO movement just to mention a few. Once we load it we can see a complex interface containing various parameters.

 

 

Unlike other competitive plugin solutions, it contains 8 different envelope engines. You can find them in the upper left section of the interface and can create some very complex sequences. In addition, if you click on the pencil tool in the bottom of the interface you get a section with various envelope shapes which are really useful. Just like all Polyverse Music plugins, it’s offering a large number of presets. So let’s see how it sounds on the chord sequence that I have made. Here is first how it sounds without it.

Furthermore, it could be interesting to apply the effect on the bassline as well. So let’s hear how that sounds followed by drums. Here is the bassline before and after applying the effect.

There are really countless options in terms of rhythmical manipulation of the sound with this plugin so I strongly encourage you to try it yourself.
