Music and sound synthesis with SuperCollider.

Example usage (after installing and booting SuperCollider):

{-# LANGUAGE DataKinds, ExtendedDefaultRules #-}

import Vivid

playSong :: VividAction m => m ()
playSong = do
   fork $ do
      s0 <- synth theSound (36 ::I "note")
      wait 1
      free s0
   s1 <- synth theSound (60 ::I "note")
   forM_ [62,66,64] $ \note -> do
      wait (1/4)
      set s1 (note ::I "note")
   wait (1/4)
   free s1

theSound :: SynthDef '["note"]
theSound = sd (0 ::I "note") $ do
   wobble <- sinOsc (freq_ 5) ? KR ~* 10 ~+ 10
   s <- 0.1 ~* sinOsc (freq_ $ midiCPS (V::V "note") ~+ wobble)
   out 0 [s,s]

main :: IO ()
main = do
   putStrLn "Simplest:"
   playSong

   putStrLn "With precise timing:"
   doScheduledIn 0.1 playSong
   wait 1

   putStrLn "Written to a file, non-realtime synthesis:"
   putStrLn "(Need to quit the running server for NRT)"
   quitSCServer
   writeNRT "song.wav" playSong
