HooverMaker is a free VST instrument that is aimed at creating massive hoover stabs found in most hardhouse, hardcore / gabbertracks that is played by underground clubs by night.

The synthesizer is a 4 oscilator broad synth that has just a pulsewidth modulated waveform + a vibrato that modulates it. The oscillators hence referred to as VCO is then connected through a filter (VCF) and then through an amplifier (VCA). The main pitch is also controllable through a pitchbend wheel and a pitch envelope (VCO EG). The filter is controllable through a filter envelope (VCF).
