I have add it to the menuentry`s like that: /path/to/script rosegarden qsynth vkeybd or /path/to/script ardour qjacktuner reegards hermann _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
