* Added new client interface functions, for sampler
  channel effect sends control:
	 lscp_create_fxsend();
	 lscp_destroy_fxsend();
	 lscp_get_fxsends();
	 lscp_list_fxsends();
	 lscp_get_fxsend_info();
	 lscp_set_fxsend_audio_channel();
  and for global volume:
	 lscp_get_volume();
	 lscp_set_volume();
