Then make sure you're repling to the "linux-audio-dev" list, and not (only) to the individual. If you're struggling with code, take a step back, and write a single email, with a direct question, that sums up what you're trying to learn. Eg: How does setValue() work to updated a widgets value in NTK, in the context of an LV2 plugin? To which I would answer: Most NTK widgets that have a "value" like a slider or a dial, derive from a base class that implements value() and value( float ); What this means for a widget, is that in order to change the value of a widget called "wid", we do this: wid->value( 0.0f ); // sets widget value to 0 What you will see here: https://github.com/harryhaaren/openAV-ArtyFX/blob/master/ui/crusher.h#L156 Is the value() call, which returns the value stored in the base class, aka 0.0f in this case. To connect an LV2 port to a widget, in port_event() have this type of code: https://github.com/harryhaaren/openAV-ArtyFX/blob/master/bitta/gui/ui.cxx#L… Which checks the port number, and assigns the incoming value to the widget, using the value( float ); call. Its pretty simple right? Cool. RE: the other emails, Yes Sorcer uses NTK, NTK is in turn based on FLTK, and to maintain backwards compatibility with existing code, the function names weren't changed.
