Hello, can anybody help me please? I am trying to use a piano app (on android device) via Midi and it connects and registers all fine. I then want to channel the keyboard and app though my headphones (plugging the headphones into the keyboard) but it doesn't work :-(. It works if I plug into the android device that has the app on it (android) but it then distorts and delays the sound. Is there something I am missing? Many thanks Nic
