SD-GATE 87 is a dedicated sidechain gate and ducking effect designed for precise dynamic control. It features two input pairs, allowing flexible routing options, and can also be used as a classic stereo input to stereo output effect while maintaining a reference section for accurate gating. This design provides users with greater control over how the gate responds to the incoming signal and its sidechain input.

The plugin offers a unique 'Duck' mode where the gate opens when the reference signal falls below a set threshold, effectively reversing the typical gating behavior. To prevent unwanted audio clicks caused by the gate opening briefly as the reference signal crosses the threshold, a 'Tail' function is included. This feature ensures the gate only opens when the reference level transitions from high to low, improving the smoothness and clarity of the effect.

SD-GATE 87 is suitable both for subtle track refinement and for creating distinctive gating effects. Its carefully crafted controls make it an effective tool for enhancing mixes by controlling dynamics or adding creative rhythmic elements. Whether you need to clean up a mix or experiment with gating textures, this plugin provides the precision and flexibility to achieve professional results.
