Wow thats a lot of interesting projects! Will definitely give these a try!
I haven’t had a chance to run it through the ringer just yet but now that it isn’t a phasey incoherent mess, I’d say its pretty good so far! I have only implemented it on my pod which I tend to rely on to verify more complex effects before putting it into my terrarium. The next step will definitely be to build the whammy I always wanted but never cared to pay for 
The CPU utilisation battle is an entire other chapter of my struggle I didn’t go into here. I basically built a dedicated project for testing run time of different math functions (atan2, sqrt, sine, cosine) in order to best optimise the processing time of my FFT window. See here
NOTE: After a good nights rest, I am starting to think maybe my understanding of exactly what fixed my project is a little off, especially regarding what I had to say regarding Arrangement of FFT Buffer Phase Bins. I will be doing more testing later to confirm I am not spreading misinfo on the web again In the meantime, if anyone wants to correct me feel free
But hey, who needs to understand their code when it works?
