ZEEK STFU v1.0.4 x64 VST3 AU WiN MAC [FREE]

ZEEK STFU is a free volume-shaping effect for producers who want rhythmic ducking, pulsing levels, or more control over a sound’s amplitude. It suits electronic music hobbyists building grooves around kick drums, bass lines, pads, and synth parts, with a quick workflow for shaping how those sounds rise and fall.

Envelope timing can follow your DAW’s tempo or respond to incoming MIDI notes, with sample-accurate operation in either mode. Tempo sync is useful for repeating patterns, while MIDI triggering lets you place volume changes around your arrangement rather than relying only on a fixed cycle. It also offers an alternative when a synth’s built-in volume envelope cannot produce the movement you need.

STFU supports two separate envelopes and lets you crossfade between them to vary the shaping. For compatible setups, it can also send CV to hosts and modular plugins. Use it in a compatible Windows DAW such as FL Studio or Ableton Live for sidechain-style movement and MIDI-driven level control.
