Such APIs include (but are not limited to) VST,\n\ +AudioUnits, LV2, LADSPA and CLAP.\n\ +\n\ +Since (a) any such plugin may be loaded by any host that supports the API\n\ +and (b) any host may load any plugin that supports the API, we consider it\n\ +self-evident that there can be no \"derivative\" relationship (in the sense\n\ +of the GPL's use of this term) between the host and plugin.\n\ +\n\ +Consequently, Ardour may load arbitrarily licensed plugins, so as to cause\n\ +interactions between Ardour and the plugin via a 3rd party API, without any\n\ +implications for either Ardour or the plugin. In our understanding, Using\n\ +such plugins with Ardour is not impacted in any way by Ardour's GPL licensing.\n\ +\n\ \n\ GNU GENERAL PUBLIC LICENSE\n\ Version 2, June 1991\n\
