Hi Aaron! A few notes on your mail: How do you use jack_lsp? Which options do you use? jack_lsp is capable of listing port properties and connections. About audio and MIDI: JACK has both audio and MIDI ports. If you want your tool to be intelligent, you might consider it. I think with options -P lists properties and with -t you can specify to only display a certain type of ports (audio/midi I suppose). How much checking do you do after all? And how much checking would you eventually be willing to use? (not connecting audio and midi ports, not connecting output to output...) I think the easiest way to have a kind of audio and midi tab, you can use different print/list commands. E.g.: l for listing all ports (probably with a hint after each name or divided in sections. Then you could have specialised listing commands la lm. I don't know: How exactly is qjackctl organised? Does it have seperate tabs for ALSA midi, jackaudio and jackmidi or only alsa and jack? Depends on how you might wish to seperate. The other main idea is of course to use different modes. In that case you might take these modes up in the prompt: jackctl (audio 'h' for help)> m jackctl (midi 'h' for help)> By the way: Thanks for the hint with l. I've just seen it a minute before I read your mail, since I saw a complete output from jackctl. Still it's very good to know.
