ABX Compressor Test VST

ABX Compressor Test VST is a free compressor VST plugin developed by Michael Gruhn Audio. Compatible OS(s): Windows.

ABX Compressor Test is a research VST plug-in that implements 18 different compressor modes – that is 18 more or less significantly different algorithms. It was created to research how a good compressor should sound (and therefore how it must be designed).

All compressor designs are feed-forward and peak-detecting. The side-chain is always not filtered. The signal path is also unfiltered, that is it contains no sound enhancing of any kind (except for the gain adjustment performed by compression).

Different modes
The different modes comprise different envelope follower types, different transfer functions as well as different inter-operation between the internal parts of the compressor. The modes are numbered from 1 to 18, the literals in parenthesis hint at the difference and can be interpreted as follows:

HQR = High quality transfer function (ratio).

LQR = Low quality transfer function (ratio).

S = Smooth operation (release).

Anyone is free to use and share this VST plug-in as long as they evaluate the different compressor modes to the best of their knowledge and report their findings and comments in this thread in the KVRAudio.com forum (where the plug-in is available for download).

A1TriggerGate

A1TriggerGate is a free gate VST, Audio Unit, AAX plugin developed by Alex Hilton / A1AUDIO. Compatible OS(s): Windows, macOS.

A1TriggerGate is a ‘Sequenced Gate’ plugin to chop up any incoming audio signal. It is a well known effect in electronic music and sometimes also known as ‘Trance Gate’ effect.

Pattern Sequence

This plugin synchronizes to the host sequencer / DAW tempo. Each internal sequencer pattern consists of 4 beats / 16 steps (or 12 steps in Triplet mode). Each step length is eighter a ‘ShortStep’, ‘LongStep’, ‘StepLink’ or ‘NoStep’ and has its own step volume fader. There are 8 independent patterns that can be switched via automation.

Integrated FX

The integrated FX (Lowpass Filter, Drive/Distortion and Echo/Delay) are designed for easy usage. There is only a minimal number of parameters to get the desired effect as fast as possible. Of course there is a ‘Global FX Off’ switch to step through all presets without hearing any of the integrated FX. Professional producers will appreciate that little feature.

Pattern Commands

In Expert Mode there a 4 pattern command tabs featuring ‘shift left/right’, ‘copy & paste, ‘random’ and ‘init’ commands eighter for the step volume values, the step lenght values or all of them. Especially the ‘random’ command on step length values gives interesting results and is a good source for inspiration.

Features:

FREE.

VST / AU / AAX for MAC & PC (32 / 64-bit).

sequenced gate.

8 patterns, 4 beats.

triplet mode.

additional internal FX (Lowpass Filter, Drive/Distortion, Echo/Delay).

all parameters automatable.
