any information site about ofxsndobj?

I just started to use OF 3 weeks ago. And I want to know about ofxsndobj… I can play oscillators, but I want to control adsr and filters.
Does anybody know any websites or books which explain how we can use these function?

Thank you


Could anyone tell me how to install the library and if there are any examples… I cannot find any in the folder. Thanks for your help in advance!
