There are a lot of Euclidean sequencing tools out there already, in both software and hardware. The premium offerings in the latter category are Elektron sequencers/ samplers/ synthesizers and the Oxi One, a pure MIDI sequencer. but there are many others. Euclidean sequencing is generally combined with things like conditional triggering (playing a note based on probability or a specific iteration of a loop or doing some sort of logic operation on another note in the sequence) and parameter locking (anchoring other parameters like velocity or control data to specific notes). I have the impression taht the authors of this project aren't very familiar with the electronic music marketplace, given that Euclidean sequencing is found even on budget gear now because it's so easy to implement and intuitive for musicians to exploit.
Incidentally, on Vivaldi (built on Chrome) this renders as black text on dark grey, making it nearly unreadable - probably because it's following system defaults, but I think a lot of people have system colors set dark by default.
