Hi Ugur, > # I do not the feasibility but if Blue have a Lisp editor, the Common > Music and Csound systems may work more seamlessly :-) While I have not done it, other users have used Common Music successfully within blue to generate SCO for Csound. One can work with common music then like any other soundObject in blue. This is done using either the External SoundObject or the ObjectBuilder soundObject, which is basically the external or python object with option for GUI. There are some examples that come with blue that were contributed by users in the blue/examples/soundObjects folder. If I remember correctly, some examples were for an older common music while others for newer versions of common music, and one was written on Windows while others on Linux. steven
