Recursive outboard processing

A continuation of my foray into recursive processing.
I previously shared a video of a prototype script I made, called ReaCursive, which, solely in the DAW and FX plugins, took inspiration from Alvin Lucier's work and ideas to recursively process source material an arbitrary number of times through the same chain of FX plugins.

I wanted to expand the idea, but instead of letting the processing happen solely in the DAW, the processing is handled by some the characterful outboard gear I have at my disposal.

I wrote a custom Reaper script, which handles most things for me:
I place some source material on one track, output routed to the FX unit.
Trigger the script and it starts recording for the length of the timeline selection.
Recording ends, playback is stopped, the newest recording is moved to the next track, where the output is routed to the FX unit again,
new recording is normalized to make up for the iteratively changes to gain, and this will happen until I terminate the script.

While the initial DAW-only recursive script allowed me to render everything offline very quickly, I now have to wait in real time and listen to the result as it is recorded.

The video showcases some results with digital reverb, spring reverb, delay and cassette tape deck.

One thing I noticed here, by mistake, is that I can record no input, and of course the normalization of the recording pulls up all the noise and hum. If I let this process run, it just keeps processing the same self noise, which can lead to some interesting sounds after many iterations.

Bonus: The visuals are made from pointing a webcam at the computer screen, while monitoring the input, so it sits within a similar realm as the audio.
