I'm not a hardcore CS, I'm just the guy that wrote SpinCAD Designer on top of ElmGen. You could start with an existing graphical editor. I'm all in favor of not reinventing stuff if possible. I think Teensy Audio Tool forked node-red. I spent an hour maybe looking at it and it would take more time than that to figure out what they did. Notably, node-red blocks have 1 input and 1 output. Teensy audio blocks have multiple inputs and outputs possible. Although not necessary, I like the "audio in one dimension and control in the other" aspect of SpinCAD Designer. Then you gotta have code templates for each target and then also some per-target means of stitching it all together. I only know SpinCAD Designer but that involves doing a topological sort of the model and then walking down it, allocating FV-1 registers and RAM as you go. My recollection of the Teensy audio tool is that it generates function calls for C or C++, which obviously wouldn't work for chips like fxCore or FV-1.
