> g_01 = whiteNoise 'α' AR * 0.05

Random filtered noise bursts.

> g_02 =
>     let n = whiteNoise 'α' AR
>         t = dust 'β' AR (mce [3, 7])
>         f = tExpRand 'γ' 20 1800 t
>         bw = tExpRand 'δ' 0.001 1 t
>         e = decay2 t 0.01 0.2
>     in resonz (n * e) f bw

Monadic form of above graph.

> g_03 :: UId m => m UGen
> g_03 = do
>   n <- whiteNoiseM AR
>   t <- dustM AR (mce [3, 7])
>   f <- tExpRandM 20 1800 t
>   bw <- tExpRandM 0.001 1 t
>   let e = decay2 t 0.01 0.2
>   return (resonz (n * e) f bw)

The same graph again, without using do notation.

> g_04 =

>     tExpRandM 0.001 1 t >>= \bw ->
>     let e = decay2 t 0.01 0.2
>     in return (resonz (n * e) f bw)
