## Plugin Hosting

Csound currently hosts external plugins using dssi4cs (for LADSPA plugins) on Linux and vst4cs (for VST plugins) on Windows and Mac OS X.

## DSSI and LADSPA for Csound

dssi4cs enables the use of DSSI and LADSPA plugin effects and synthesizers within Csound on Linux. The following opcodes are available:

- dssiinit - Loads a plugin.

- dssiactivate - Activates or deactivates a plugin if it has this facility

- dssilist - Lists all available plugins found in the LADSPA_PATH and DSSI_PATH global variables.

- dssiaudio - Process audio using a Plugin.

- dssictls - Send control information to a plugin's control port.

See the entry for dssiinit for a usage example.

| Note
Currently only LADSPA plugins are supported, but DSSI support is planned.
