DeepMind 12 control panel ready and an oscilloscope for web sessions

The control panel for Behringer DeepMind 12 is ready, due to its effects section, the implementation took a little longer than I expected. In addition to the new control panel, I implemented an oscilloscope functionality for web sessions, it can be found below the keyboard in its own tab. The oscilloscope can be attached to the top or bottom of the page, so that you can tweak the sound and see (and hear) the results immediately.
