What FireChild does
The plugin aims to emulate the characteristics of the King Compressors from the 1950s, which the developer describes as vintage variable-mu units that use vacuum tubes to set the reduction gain. FireChild includes four models rather than one, and a clean mode is available as an off setting for the tube stages.
Six release modes are included, each emulated and sampled from the originals, and a knee control adds further shaping to the compression curve. The plugin also adds a full side-chain section that the originals did not have. A selection of presets is included to start from, or the user can build a setting from scratch. FireChild is sold as a paid plugin with a trial available.
Key features
- Four vari-mu models. FireChild offers four compressor models based on the King Vari-Mu design, including a clean version with the tube stages switched off.
- Three tube models. Tube models A, B and C are driven hard at the input stage, which the developer presents as the main source of character in the compression.
- Sampled gain stages. The compression curves are produced by sampling real hardware units at multiple stages of gain and compression.
- Six release modes. Six release modes are provided, each carefully emulated and sampled from the original units.
- Knee control. A knee control gives further shape to the compression characteristic beyond the basic threshold and ratio settings.
- Full side-chain section. A side-chain section is added that the original units did not have, giving the user more choice in how the compressor reacts to the signal.
- Presets and build from scratch. A selection of presets is included as a starting point, and the user can design a setting from scratch.
