The Dubspot verdict

The Dubspot verdict

A two-section chorus that can turn into texture. REACT, SPACE, SWIRL, WEAVE, and QUAD on top of a global tone desk. £35 intro against £75.

Best for Producers who want a chorus that can also write atmosphere, with two independent rates and a zero-latency limiter.

Pros

  • Two independent sections with rate, depth, detune, phase, pan, level
  • REACT, SPACE, SWIRL, WEAVE, and QUAD
  • VINTAGE, HPF/LPF, zero-latency limiter, CPU-light
  • £35 intro against £75; 3 activations; full-feature trial

Cons

  • Sold direct, no Plugin Boutique listing
  • Windows has no AU
  • More controls than a one-knob chorus

Field notes

Overview

quadCHO is fedDSP's two-section chorus. Each section has rate, depth, detune, phase, pan, and level. REACT, SPACE, SWIRL, WEAVE, and QUAD sit on top. A global desk adds MIX, DEPTH, TILT, SAT, WIDTH, VINTAGE, filters, and a zero-latency limiter.

The intro is £35 against a £75 regular. Formats are AU, AAX, and VST3 on Mac, and VST3 plus AAX on Windows. Native on Apple Silicon and Intel. Sold direct from feddsp.com.

Compared with Syntorus 2 it is two live sections plus motion controls, not a triple-path analogue chorus. Compared with Thorus XT it is a playground, not a digital-plus-BBD pair. Read the quadCHO first look.
