Is there a way to have a hierarchy of cycles?

For instance:  
In every m//nth cycle, I want d1 $ f\_m (so f\_1 in each cycle of supercycle 1, f\_2 in each cycle of supercycle 2, etc.)

I don't think ``whenmod" is appropriate since  
a) it has type  
whenmod :: Int -\> Int -\> (Pattern a -\> Pattern a) -\> Pattern a -\> Pattern a  
while what I'm looking for is  
supercycle :: Int -\> Int -\> [Pattern a] -\> Pattern a

and  
b) I want it to change behavior every m//n cycles, instead of m % n (which will change every cycle).

Thanks!

I don't quite understand the question. What does "m//n" mean?

Is this a "cycle of cycles" in your sense?

```haskell
 d1 $ slow 4 $ s "superpiano" + note ( scale "major" (squeezeJoin (fmap (\x -> run (pure x)) (run 8))))

```

outer cycle: `run 8`, inner cycles: run up to current value of outer cycle.
