Hi! You are all certainly very pround of and happy with pulseaudio, which is now the basic sound system of Ubuntu 9.10 and Fedory 11 and possibly others. I'm the author of the musical score editor NtEd http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/nted.xhtml and unfortunately, I must state: Pulseaudio has terrible consequences for this (special, but often used) sort of applications. Especially, if the user has no hardware synthesizer and must use software synthesizers like TiMidity. Please read which bad news I had to include into the NtEd documentation: http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/doc/ch01s50.html -- J.Anders, GERMANY, TU Chemnitz, Fakultaet fuer Informatik
