+/**
+   @defgroup plugin provided bypass
+
+	 A port with the designation "processing#enable" must
+	 control a plugin's internal bypass mode.
+
+	 If the port value is larger than zero the plugin processes
+	 normally.
+
+	 If the port value is zero, the plugin is expected to bypass
+	 all signals unmodified.
+
+	 The plugin is responsible for providing a click-free transition
+	 between the states.
+
+	 (values less than zero are reserved for future use:
+	 e.g click-free insert/removal of latent plugins.
+	 Generally values <= 0 are to be treated as bypassed.)
