Firstly, if you do not use LMMS2.2 i strongly recommend you to upgrade1 2.2 supports effect best!
OBS! In order to work in LMMS Your effect must be VST2!
Unpack the zip, and copy the files to a new folder in the folder you have defined as VST-plugins folder in Edit|Settings| directories.
The effect will then appear in the list of FX-plugins.
