All possible divisions of a number.
I’m trying to make a patch that generates rhythms that fit within a specified bar length and only use note values that are pre selected.
So for example if I have a bar of 4/4 and I have half-notes, quarter notes and eighth notes I would have all possible rhythmic variations using these note divisions that fit within the 4/4 bar.
Ie. one would be: X x x x X x X X
another could be X x X x X x x x
etc. etc. until all variations are reached.
Sounds like you’re basically building a euclidian rhythm generator?
I guess so. And I’ve looked into the euclidean algorithm. But that distributes beats equally across a given bar length.
What I want to find out about is being able to quantize these distributions using a selected variety of divisions and then to iterate through all possible variations to be probably stored in a dict or a coll.
I’m just wondering what sort of approach I should take to this. and if anyone has made anything similar before.
I think this thread may have what you want–
Aha, thanks Terry. That seems to have done it! It is a case for a looping algorithm then I see.
I wonder if this would be more efficient in js as opposed to max?
What do you think?
It’s a pretty simple algorithm, and if you’re doing it to generate rhythms, I can’t really see the advantage using js (aside from compactness), even in real-time applications. for a more informed opinion someone with js experience would be better qualified to comment
This should get you started, it’s a brute force approach which will put all the permutations into a coll. You could use filtering on the output of the uzi’s to get rid of lengths you are not interested in.

Thanks guys. Both are fantastic approaches. I’ll do some modifications and shall report back with the patch I’m using this method in.
Man, those are both just brilliant! My head is spinning…
