Hi, Happy New Year 2008 to all! Like it's written there: http://caml.inria.fr/pub/docs/manual-caml-light/node16.html It is possible to make sounds with Caml. This should play an A during one second: [code] #open "graphics";; open_graph "";; sound 440 1000;; [/code] But on my Mac (under X11, actually), I only get the system beep :/ Does anybody know why? Thanks by advance. P.S: I programed a little music interpreter which works for now only on Windows... -- Jill-Jênn http://mickay.jill.free.fr/score/
