The Whole Bench — All 13

Every plugin in the line: the full vocal chain, EQ, tuning, compression, reverb, both saturation engines, the mastering engine, the ad-lib designer, the resonance tamer, the $toney series, and the one-job utility.

$627 separately
$279

KillaVox

The full 8-module vocal chain in one plugin — EQ, compression, de-essing, saturation, and more, wired in the order an engineer would chain them.

Nocturnal Fire Master

AI automated mastering. Drop your mix in — the engine listens, analyzes, and masters it: corrective EQ, glue, imaging, loudness, and a −1 dB ceiling.

EQ

KillaEQ

Pro EQ built to the Nocturnal Fire Pro EQ standard — surgical bands, musical shelves, and a painted interface that looks like nothing else in your DAW.

KillaTune

Vocal tuning and pitch correction — from invisible fixes to hard-tuned hooks, with a key and scale workflow that stays out of your way.

KillaComp

Compression that glues a mix together — vocals first, but just as happy holding a whole track together.

KillaVerb

Reverb — from tight rooms to cathedral space, with the cyan waveform display Kaspa picked for it.

Nocturnal Fire

Analog saturation & distortion heat — five flavors, from subtle tube warmth to full inferno, with auto gain so you judge tone, not loudness.

KillaHeat

Saturation heat for tracks that need teeth — analog-style drive with the Nocturnal Fire character, aimed at anything that sounds too clean.

KillaSmooth

Dynamic resonance suppressor — hunts down harsh build-up, piercing frequencies, and mouth clicks in real time, without dulling the vocal.

KillaDubs

Ad-lib and background-vocal designer — the separated, polished ad-lib sound the industry stacks five plugins to get, from one interface.

$toney Sauce

$toney series. A one-knob vocal finisher — cleanup, presence, glue, warmth, and air riding a single knob, in three styles: Clean, Sauced, Aggressive.

$toney Smok'N

$toney series. Smoke & vintage character — tube grit, a resonant smoke filter, thickness, and slow tape drift for vocals that feel too digital.

KillaStop

One-job utility — quick, clean, done. The simple tool you reach for when a track needs one thing handled fast.
