Yes, the above is the minimal roster. Sometimes I also include Hydrogen and Yoshimi but I don't think that the use of THESE apps is a factor > What is not working with recording via jack_capture? Essentially, sometiomes and for reasons unknown, jack_capture either starts capturing but the file ends before the first note ends OR jack_capture just records an empty .wav file The other day I had an additional app running (could have been Audacity) and all I had to do was kill it for the next invocation of jack_capture to work just fine. > IIRC jack_capture without any options will connect (jack) to the system > out ports and start recording straight away... > > If the scenario is the above what I would do is: > > 0.

See also all jack_capture options via: > > jack_capture -help2 Using mostly Suse Leap or Tumbleweed I've been getting good results but the cited failure has been a regular 'vistor' for unknown reasons. At such times none of the above helps but most other times it works with default settings without the above. Right now it works fine under Tumbleweed but withg Tumbleweed I cannot get Audacity running: ______________________________________________ (process:3873): Gdk-CRITICAL **: 18:13:52.599: gdk_screen_get_root_window: assertion 'GDK_IS_SCREEN (screen)' failed ---------------------------------------------- It's been failing with Leap for several days. The thing is that for a productive session I need all of the following to work qjackctl (jack) jack_capture qsynth hydrogen yoshimi rosegaden audacity sonicvisualiser kdenlive simplescreenrecorder but even though I use 7 different distros there are times when not one of them allows this much. This time a file WAS produced nbuty it is truncated to the start: strace is way over ny head but here it is https://paste.opensuse.org/pastes/7dbad6223d33 the wav file image: http://www.trixtar.org/temp-pub-buffer/failed-jack_capture-wave.png _______________________________________________ Rosegarden-user mailing list Rosegarden-user@lists.sourceforge.net - use the link below to unsubscribe https://lists.sourceforge.net/lists/listinfo/rosegarden-user
