undefinedを埋めてく感じでシンセ毎に機能を作っていく感じになるはず https://github.com/tokiwoousaka/ArareDSL/blob/master/src/Sound/Arare/ArareDSL.hs ただし事実上フレーズの多相化みたいな事は難しいっぽい。

同じ関数に違う数の引数を指定した関数とかを、一つの演算子に適用する感じ。

リスト処理で簡単な波形を作ってSarasvati(開発版：https://github.com/tokiwoousaka/Sarasvati/tree/develop/4 )に流し込むテスト。
module Main where
import Sound.Sarasvati
import Control.DeepSeq
import Control.Arrow
main :: IO ()
main = do
putStrLn "music building..."
sarasvatiOutput defaultConfig . vol 0.5 0.5 $!! concat [music, music, r 8]
return ()

モナド則： (m >>= g) >>= h == m >>= (\x -> g x >>= h)
定義： f >=> g == \x -> f x >>= g
命題：(f >=> g) >=> h == f >=> (g >=> h)
(f >=> g) >=> h
== (\x -> f x >>= g) >=> h -- (>=>)の定義
== \y -> (\x -> f x >>= g) y >>= h -- (>=>)の定義
== \y -> (f y >>= g) >>= h
== \y -> f y >>= (\z -> g z >>= h) -- モナド則
== \y -> f y >>= (g >=> h) -- (>=>)の定義
