Trying to get my head wrapped around this and looking for a little guidance with respect to Elk on the Raspberry Pi. I understand writing a plugin with the Juce framework, compiling it with the Elk Juce fork, and then running it within Sushi. It sounds like one could develop and debug the plugin on the platform of choice, then cross-compile using the Juce fork and then run within Sushi. That all seems to make sense.
What I’m missing is the approach one would take to implement a GUI on the same Raspberry Pi to provide dynamic control of the plugin and audio parameters. From what I’ve read, Elk doesn’t support a Juce-based GUI app to do this. Is there an example of this anywhere? Or is it the case that the intent is that parameter control is all hardware based, i.e. knobs and sliders?
