used with any <code>UI</code> type to plug a GUI, MIDI or OSC controller on the DSP object, like it would be done with a DSP program compiled to a C++ class (the generated <code>mydsp</code>  class is also a subclass of the base <code>dsp</code> class). This is demonstrated with the <code>my_ui* m_ui = new MyUI();</code> and <code>m_dsp-&gt;buildUserInterface(m_ui);</code> lines where the <code>buildUserInterface</code> method is used to connect a controller. </p>
