I wish… I’ve checked all my .rb files, and deep-searched the forum here with no luck.
In case it jogs anyone elses memory, I think it was called ‘By the Bay’ or similar, and it
had ‘day’ and ‘night’ modes… and some hellishly complex maths in it. I think they were
also creating loops programatically, as the song progressed… but it was also very melodic
and soulfull.
It might also have been posted under ‘Clouds’… but I cant find that either…
I’d like to bring your attention to this post as well… his code/sound really attracted my ears.
