What it does

Drawn, not detected.

The depth of ducking is drawn as a curve rather than derived from the input's own level, so every hit ducks identically regardless of how loud the source is. That is what makes it a rhythmic tool rather than a dynamics one.

Place it on a bass, synth, pad, instrument or effects return, and it steps that signal out of the way of the kick — either the whole signal, or only the content below a crossover, so a bass can lose its sub around the kick while its harmonics and note definition stay put.

Sixteen original curves ship with it, from a near-invisible 3 dB dip to a hard gate. Or draw your own: drag the wave itself to move a control point, drag a segment to bend it, double-click to add a point, alt-click to remove one. The line follows the pointer, so the shape is drawn rather than dialled.

Key features

01

Three ways to decide when

Host mode runs a free-running envelope against the musical grid from host PPQ position. Sidechain mode fires one shot per detected transient from an audio onset detector. MIDI mode fires one shot per note-on, with sample-accurate offset.

02

Two ways to decide what

The whole signal, or only the content below a crossover.

03

Sixteen curves, plus your own

The handles only appear when the pointer is in the display or your own curve is in use, so the display stays clean while you are listening rather than editing.

04

Zero latency by default

Lookahead is off, and when engaged the plugin reports exactly the samples it uses — not a worst-case allowance held permanently. Lookahead is deliberately non-automatable: changing reported latency mid-transport is disruptive in every DAW and fatal in Pro Tools.

05

The crossover always runs

It costs nothing measurable, and skipping it when idle would leave stale filter state and a 25 ms settling dip on re-engage.

06

Session compatibility is a commitment

Parameter IDs, ranges and order are permanent, with session and preset state versioned independently of the product version and a migration path for old sessions.
