Overview
apulSoft apQualizr2 is an equalizer audio plugin. Filter bands can be graphically edited on top of a frequency analyzer display. The module tray enables module-based modulation of various filter parameters.

apQualizr2 can be used for all standard EQ applications. It can create modulation and dynamics effects thanks to the included dynamics and super-flexible LFO modules. The built-in midi module provides midi control of most things.

Filter Technology
apQualizr2 filters are based on a unique method to match ideal frequency response curves over the entire frequency spectrum. Applicable filter types have adjustable steepness (adjustable number of poles/slopes) and can be individually switched to mid-side processing
Filters have a ++ poles mode where slopes get extremely steep: the full gain change is covered within one semitone. Spectral tilt and variable-slope low- and highpass filters allow continuous tilt/slope values and modulation. apQualizr2 includes phase correction engines to achieve minimal, analog, mixed and linear phase.

Main Features

• 4 phase correction engines: minimal, analog, mixed and linear.
• Graphical editing of filter parameters.
• Unlimited number of filter bands.
• Special ++ filter mode for extremely steep slopes.
• Zoomable FFT-based frequency analyzer displayed beneath the filter curves.
• Phase reponse graph.
• Frequency band solo feature: hold alt to solo frequencies in mouse proximity at any time.
• Filter parameters can be modulated by a configurable network of modules.
• Modules included: LFO, dynamics, scope, mix, split, knobs, midi in, sidechain.
• Quick eq setup using double-click zones and create-on-drag from the sum curve.

• Plugin formats: AudioUnits/AAX/VST/VST3 on macOS (intel/arm 64-bit) and Windows (32/64-bit intel)
• Built-in system-wide preset management with import and export of preset files, compatible across platforms and hosts using a human-readable xml file format.
• Import of equalizer config text files from various applications (including AutoEq and REW).
• Bright & dark color schemes and support for user defined color schemes.

Note:
I messed up my installer script. Enable the VST & VST3 option in the installer, and the VST3 file will be where your specified VST path is.
