version of Csound? Diskin used to have a bug in some versions. Try diskin2.

Maybe I'm missing something really obvious here, but I can't see it! I would appreciate any help, and thanks in advance Emerson Dr Victor Lazzarini, Senior Lecturer, Dept. of Music, National University of Ireland, Maynooth Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"
