# LADSPA Plugins

LADPSA Plugins are not native to LMMS, but are bundled with it; they are entirely controlled via knobs, sliders, and buttons, with no other graphical user interface.

As these plugins are not maintained by LMMS, they are not documented here, but some reference links are provided below:

* C\* Plugins: <http://quitte.de/dsp/caps.html>
* Calf Plugins: <https://calf-studio-gear.org/>
* Steve Harris: <http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html>

* Other: <http://linux-sound.org/plugins.html>

{% hint style="warning" %}
Some LADSPA plugins may introduce:

* [DC offsetting](https://docs.lmms.io/user-manual/resources/glossary#id-7.1.4.2-dc-offset) (although this can be mitigated by placing the "DC Offset Remover" LADSPA plugin in the troublesome instrument or FX bus)
* Phase misalignment
* Idle noise
* Extremely loud clipping/noise

Be careful when adjusting and using these plugins!
