@Christoph-Hart Thank you for the nudge I was trying to find a good example to build from and this is giving me a better sense of the folder/file hierarchy relationship. I am still in the poke around the codebase and find out phase so will report back once I understand more.
Happy to make a pull request to add it to the official version of HISE as well if I get it working, but I know this is a pretty niche case so unless there is a demand for it I won't bother!
