Quick Sidechain — Advanced Sidechain Compressor VST Plugin (Windows)

Windows VST only — MAC / AU Coming Soon

A sidechain compressor built for full control over the shape of your ducking — not just depth and speed, but the actual curve, frequency range, and stereo behavior.

Curve editing:

  • Fully customizable envelope curves with draggable points — shape your ducking exactly, not just pick a preset
  • Linear, Power, and Exponential curve tension for different release characters
  • Micro-timing offset to shift the whole curve early or late — catch transients before they hit, or lay the pump behind the beat

Trigger modes:

  • Host BPM sync (1/4, 1/8, dotted, triplets) for grid-locked house, techno, and trance pumping
  • MIDI note trigger for syncopated patterns, breakbeats, and live playing
  • External audio sidechain input with adjustable threshold and ratio, for reacting to real drum loops
  • Free Hz/ms mode — untethered from the grid for sound design and LFO-style effects

Frequency and stereo control:

  • Built-in crossover to duck low end only, leaving your highs untouched
  • Mid/Side processing — duck the center or the sides independently
  • Stereo phase offset between L/R for auto-pan style spatial movement

Visual feedback:

  • Real-time oscilloscope overlaid directly on the curve
  • Ghost waveform of your input signal, so you can align curve points to the actual kick transient by eye, not guesswork
  • Resizable GUI

Utilities:

  • Delta listen mode — solo exactly what the sidechain is removing
  • MIDI CC/Note output, so your envelope can modulate other plugins or hardware
  • Up to 4x oversampling for clean audio under aggressive, fast ducking
  • Preset save/load, shape randomizer, copy/paste for curve edits

Good for: house, techno, and trance pumping that needs a specific shape instead of a generic duck; producers who want to see exactly where their curve is landing against the kick, not guess by ear.
