Most of the jack_midi_... functions here need a nframes argument. I had seen a funcion to get this from jack_get_buffer_size(_client) or from info->nframes. Subtracted frame offsets if I knew them? I can send you the modified sources if you want When jack is running and I start it, I get ports created for everything that shows in qjackctl's midi connections pane. I see nothing different in qjackctl. If this what it should be doing and then, how do I connect them? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
