The Envelope Follower reading a kick drum.

Turns a track’s level into movement. Point it at a kick to duck a pad, or at a vocal to open a filter as the singer pushes. The source can be the same track or another one.

Control Range What it does
Source any track Whose level to follow. Starts as the modulator’s own track.
Attack ms How quickly it rises to a hit.
Release ms How quickly it falls away afterwards.
Depth 0 to 100% How much output it produces.
Gain 0.1 to 16x Fine level boost for the source.
Boost 0 to +48 dB Coarse level boost, for quiet sources.
The Steps editor with an eight-step pattern of bars, the playing step highlighted

Steps, an eight-step pattern synced to quarter notes.

A step sequencer for parameters: up to sixteen steps, each one a held value, advancing on a beat division you choose.

Drag a bar to set its value, or press the dice to roll the lot. The highlighted bar is the step playing now. Randomising is the quickest way to land on a pattern you would never have drawn on purpose.
