In the developer´s page the free version it´s on the “Old VST Plug-ins Pack” section.
“Glitch is one of the more interesting free VST effect plugins available. Glitch from DBlue (Kieran Foster) is a good multi-effect processor with some unique features that enables it to stand out from the long list of available free VST effects.
You can think of Glitch (Current Version 1.3.04) as a kind of multi effect sequencer. The incoming audio gets divided into individual steps of various lengths. A variety of effects can then be applied and mixed into those segments and the sequence looped.
There are controls to adjust the level and amount of the effect as well as the length of the sequence and mix of the effect on the original sound.
The effect for each segment can be random, preset to one of the effect modules or bypassed to the original clean audio.
