Polymeter is a free, open source MIDI sequencer for music that's in multiple prime meters (1, 2, 3, 5, 7, 11, etc.) simultaneously. Each track has its own loop length, and when the lengths differ, the tracks "slip" (or shift phase) relative to each other. I post development notes about it here.

Time to repeat: longer than the universe has existed
After a day spent studying number theory, my Polymeter sequencer has
something I always wanted: a "Time to Repeat" command! The command
computes how long it would take for the selected tracks to repeat, in
both beats and time (along with the greatest prime factor) and displays
the results. I tried it on my test track that uses all prime meters
less than 32 (except 23). "Only" 22,428 days. That's longer than I've
been alive! That's some serious polymeter. During stress testing I made
some combinations that would take trillions of years. Thomas Wilfred
would be impressed. https://en.wikipedia.org/wiki/Thomas_Wilfred
