Type: `rand :: Fractional a => Pattern a`

**rand** is a continuous pattern that generates a pattern of (pseudo-)random, floating point numbers between 0 and 1. For example to randomly pan around the stereo field you can:

`d1 $ sound "bd*8" # pan rand`

Or to enjoy a randomised **speed** from 0.5 to 1.5, you can add 0.5 to it.

`d1 $ sound "arpy*4" # speed (rand + 0.5)`

# irand

Type: `irand :: Num a => Int -> Pattern a`

**irand** is similar to rand, but generates a pattern of (pseudo-)random integers between 0 to n-1 inclusive. Notably used to pick random samples from a folder.

`d1 $ sound "amencutup*8" # n (irand 8)`
