#3I'm fascinated by this concept and I've even had some ideas about making something similar, though I haven't worked them out
I'd love to look at the source code for this.

#4I don't understand why and how it periodically resets.
its an algorithm that's been popular in music programming the past several years. there are a bunch of implementations of it.
its a method for evenly distributing x pulses along a grid of y steps.
4 / 16 is house kick 5 / 16 is a dancehall beat
start by setting all steps to 16 (the grid size), offset to 0 and vary the pulse setting and you will hear how they are distributed along the steps.
good simple explanation with python implementation:

I usually call it bjorklund.
I once used it to evenly distribute promoted content across slots on a website.

There's a popular paper on the technique by Godfried Toussaint that explores it in depth: http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf

#6I don't understand why and how it periodically resets.
If the least common multiple of two elements is high, the rhythm would have a very long period, which doesn't sound very well. Three elements of periods 16,9 and 7 would have a period of 1008 steps, which at a tempo of 100 would take 10 seconds to reset. That's not a rhythm, that's a tune.

Are you referring to the adjustable reset counter in the bottom right (which by default resets every 32 steps)? I wish the option were available to disable it and simply have the rhythm reset at its natural period. Alas...

#9Warning for all those with headphones on:
If you navigate to a different tab, and then come back to groovemechanics.com, the sound pops in VERY LOUDLY...it was painful and a bit scary to my eardrums.
Other than that, though, this is really cool!
