dssiactivate is used to activate or deactivate a DSSI or LADSPA plugin. It calles the plugin's activate() and deactivate() functions if they are provided.
ktoggle - Selects between activation (ktoggle=1) and deactivation (ktoggle=0).
dssiactivate is used to turn on and off plugins if they provide this facility. This may help conserve CPU processing in some cases. For consistency, all plugins must be activated to produce sound. An inactive plugin produces silence.
Depending on the plugin's implementation, this may cause interruptions in the realtime audio process, so use with caution.
dssiactivate may cause audio stream breakups when used in realtime, so it is recommended to load all plugins to be used before playing.

Please note that even if activate() and deactivate() functions are not present in a plugin, dssiactivate must be called for the plugin to produce sound. |
