great video and explanation!
Just reviving this thread to say: really a sweet addition to TT.Am eagerly awaiting the TT expander sets to have the extra 4 triggers run the ER while others are busy complicating things in other ways!
Glad you're having fun!
There is also this excellent video from @dudadius
and a riff on it by @carvingcode
(both of which were posted on the Latest tracks + videos thread.)
There's some nice info on Euclidian rhythms here btw. Wish I had a teletype.
