Dynamics

Eleven nodes that react to how loud a signal is — taming peaks, opening up quiet parts, gating noise floors, or limiting to a ceiling. The four Native nodes (Compressor, Expander, Gate, Limiter) are the time-domain workhorses, behaving the way every hardware sampler’s onboard dynamics did, with the controls you already know. The seven spectral variants are where K2K extends the model: Spectral Compressor applies independent compression per frequency band, so you can tame harshness in the 2–5 kHz region without flattening the bass; Spectral Gate and Spectral Gating mute frequency regions individually; Spectral Ducker does sidechain ducking per band rather than across the whole signal; Spectral Expander and Spectral Limiter apply the same logic to expansion and limiting; Spectral Transient Shaper separates attack from sustain across the spectrum and lets you shape each independently. Use the time-domain ones for global level work, the spectral ones for surgical frequency-aware moves.
