A while back I was interested in finding more realistic dub twang-delay sounds in VST form, which was discussed in this thread. As far as I am aware, the authentic spring-twang sound is currently impossible to re-create in software, as it relies on having a real spring and something to twang that spring - imagine trying to emulate those physics with maths!

If you have ever watched a horror movie, you know how sound effects can make you jump you out of your seat. Those sound effects would make for a nice article. Ghost Notes however, are an entirely different subject.

What are Ghost Notes?

The Ghost Notes technique allows you to glide effects from one note to subsequent notes. On synthesizers the same effect is usually achieved with an LFO in combination with the Legato mode.

This article goes deep into the usage of the Filter2 effect for shaping and controlling the sonics of your song mix. It doesn't matter which genre of music you compose in, as these concepts are transferable. Before we go into detail, please look at Beatslaughterer's article on the explanation of filters; I'll be assuming the readers understanding of some basic terminology as we move through the concepts.

Introduction

This is fairly basic stuff and pretty obvious to most, but since the topic came up a couple of times in the IRC channel, I have made this basic tutorial with pictures to visualize the filtering process.

I have used the free effects from GVST. You can get them here: http://www.gvst.co.uk

Whatever is explained here also applies to the internal filters of Renoise.
