In 2019 I made a post with a digital implementation of Rob Hordijk Blippoo Box on sccode attached wih the following description:
"This is a implementation of the blippoo box as it is documented in the article "The Blippoo Box: A Chaotic Electronic Music Instrument, Bent by Design" by Rob Hordijk. i saw on Richard Scotts blippoo box some parameters that are not documented as such in the document so i added them... thats why it has more parameters. I put a Limiter onto the output to make sure it doesn't get too loud.
unfortunately i didn't know how to make the distortion inside the filter that rob describes.
have fun"
someone put it into norns, so now some people actually play with it.
