Type: `euclid :: Pattern Int -> Pattern Int -> Pattern a -> Pattern a`

**euclid** creates a Euclidean rhythmic structure. It produces the same output as the Euclidean pattern string.

For example:

`d1 $ euclid 3 8 $ sound "cp"`

is the same as

`d1 $ sound "cp(3,8)"`

**euclid** accepts two parameters that can be patterns:

`d1 $ euclid "<3 5>" "[8 16]/4" $ s "bd"`

# euclidInv

Type: `euclidInv :: Pattern Int -> Pattern Int -> Pattern a -> Pattern a`

Inverts the pattern given by `euclid`

. For example,

```
d1 $ stack [euclid 5 8 $ s "bd",
euclidInv 5 8 $ s "hh27"]
```

to hear that the hi-hat event fires on every one of the eight even beats that the bass drum does not.
