Thanks, @CountModula . Yeah, my usual advice is the cliche - just write it and get it working, worry about CPU later, Otherwise you will probably end up optimizing something that doesn’t matter.
I put all my propaganda (I mean research papers) over in my “demo” repo. Links are on the main readme, including the old “classic” you refer to: GitHub - squinkylabs/Demo: A collection of code and articles of interest to VCV users and developers.
btw, imao there is a lot of “good stuff” over in that repo, esp the documents.
