Good Free Envelope Filter Vst Plugin

It’s really more than a filter !
it’s 4 filters (or other effect : distorsion, volume) in parallel, with envelop following and “tridimensional” LFO to drive them.

Minion in full effect : come on and riiiiiiiide !

3. Blue Filter

more information & download @ http://www.digilogue.de/index_download.htm

This VST plugin is very old too ! But it does the job.
The “amount” and “slope” parameters for controlling the envelope follower is the key to make it sound funky. But don’t push the amount too hard, or the plugin will behave strangely (audio bug).
Click on the “Frequency plot” tab to show the filter transfer function.

Lowpass for all !
