Here is my entry for this challenge. I decided not to use the website to generate the bianry string, but to do that within sonic pi itself. It makes it easy to update and try other strings.
I also liked the recent post by @theibbster for a chord progression tool which I developed and used in my code.
EDIT just noticed a couple of glitches in the soundcloud file. I won’t update it, but if you play the SP code it should sound correct.
You can hear the result on soundcloud, with the code link below
