Reverb (Native)

Parameters

Room Size — Sets the perceived size of the simulated space, from a small chamber (low values) to a vast hall (high). Internally this controls the feedback inside the reverb’s recirculating delay lines: more feedback means a longer tail and a larger-feeling space. Pair with damping to define the character — a large bright room sounds very different from a large dark one.

Damping — How quickly high frequencies decay inside the reverb tail. Low values give bright, glassy, metallic tails — useful for shimmer and synthetic ambience. High values darken the tail as it fades, mimicking how real spaces absorb treble through air and soft surfaces (carpet, drapes, wood). Pairs with hi_cut_hz for global brightness sculpting.

Dry/Wet — Equal-power blend between the dry signal (0) and the reverb tail (1). The reverb processor outputs 100% wet internally; this control mixes that against the original. As with other K2K node dry/wet controls, this one is node-specific and doesn’t apply when the same reverb runs in a Player FX slot.

Additional controls

Predelay Ms — Delay between the dry signal and the start of the reverb tail. Small values (0–20 ms) feel natural; medium values (30–80 ms) push the reverb behind the source, leaving the dry signal clearly forward and adding clarity to vocals or leads. Large values approach a slapback-then-tail effect, useful for dub and dramatic ambience.

Width — Stereo width of the reverb tail. 0 collapses the tail to mono (a tighter, more centered sound), 1 spreads it fully across the stereo field. Useful for keeping bus reverbs in check (narrower) or for making pads and atmospheres feel huge (wider). The dry signal isn’t affected.

Er Level — Level of the early reflections — the discrete bounces off nearby surfaces that arrive before the diffuse tail builds up. ER is what gives a space its size and shape cues; raising this puts the listener closer to walls. Lower it for a more diffuse, “tail only” sound.

Modulation — Subtle pitch modulation inside the reverb tail. Very small amounts (0.1–0.3) prevent the metallic ringing that algorithmic reverbs can develop on sustained tones; larger amounts add a chorused, watery character. Useful for thickening pads or for warbly, lo-fi ambience reminiscent of tape-delayed reverb chambers.

Lo Cut (Hz) — Highpass filter on the wet signal. Cuts low frequencies out of the reverb tail to keep it from muddying up bass and kick drums in a mix. Standard practice on busy material is to set this around 150–300 Hz.

Hi Cut (Hz) — Lowpass filter on the wet signal. Tames the top end of the tail, useful for darker, more vintage-feeling spaces or for sitting reverb behind a bright source without it sizzling on top. Acts globally on the tail, in addition to the per-comb-line behavior of damping.

Freeze — Locks the reverb tail into infinite sustain — input stops feeding new energy in but the existing tail recirculates indefinitely. Great for pad-style drone effects, ambient beds, or holding a single chord while the rest of the arrangement moves. Toggle off to let the held tail decay naturally.

About Reverb (Native)

Native Reverb is K2K’s algorithmic reverb workhorse — a tunable space modeler with separate controls for size, damping, predelay, width, early reflections, modulation, and high/low cuts on the wet signal. room_size + damping is the primary character pair: small + dark = booth / vocal chamber; small + bright = tile / shower; large + dark = warm hall (Lexicon 224 / Bricasti M7 territory); large + bright = plate (EMT 140 / Eventide H8000 territory). predelay_ms is what separates the dry from the tail and is critical for vocal clarity (30–80 ms keeps the vocal forward while the reverb sits behind). er_level controls the discrete early reflections that give a space its size cues — drop to taste-shape “tail-only” reverbs. modulation adds subtle pitch movement to break up the metallic ringing that algorithmic reverbs develop on sustained tones (pad / synth material especially). freeze locks the tail into infinite sustain — pad-style drone effect, useful for ambient beds. lo_cut_hz + hi_cut_hz keep the wet signal from muddying bass or sizzling on top. Compare with convolution reverb / impulse-response approaches for capturing real spaces; Native Reverb is parametric and deliberately tunable, suited to creative space design rather than literal room emulation.
