Nice :) I did this for my Axe-Fx II and III a long time ago, but I never published any of it for fear of being sued. Really, I just wanted to learn about DSP techniques and that was enough for me.
Either way I don't blame you for not writing it up. The same guy just recently accused another industry player of "infringing on [his] idea" with a product because he "filed a preliminary patent". I've been using Fractals since long before they were cool but based on the guy's forum posts I think he's having a hard time navigating the modern internet cultural landscape (the tenuous nature of his legal argument notwithstanding). It's a real shame as he's clearly super talented but I think trolls have gotten to him.
