Hello,

                  I want be able to control echo effect  with toggle controller, so  I created method echo and after that used controlEvent method, but none of these technique worked for me, I guess I need some kind of setter, but don't know which one, maybe somebody know how to turn off/on echo effect with toggle ?

                                                                                                                                        

                                                                                                                                                  thanks for help
