ZEEK has released a free volume shaper plugin as part of this year’s KVR Developer Challenge contest.

STFU is designed as a tool to create sidechain type volume envelope effects. The plugin can be synced to host bpm or triggered by MIDI notes.

Using MIDI trigger, you can overcome limitations of very many synth volume envelopes for a myriad of purposes.

STFU can also output CV for use with lots of hosts and modular plugins. And if that isn’t enough, you can set up 2 separate envelopes and crossfade between them for all sorts of cool stuff.

The plugin is available as a free download in VST3 and AU formats for Windows and Mac from the ZEEK website.
