I don't know if this adds anything, but i use an NSM sessions with jackpatch, jack keyboard into a synth,and plugins with and without non-daw and with either the PI's default soundcard, or with usb soundcards.
if i use the usb soundcards I have to open qjackctl to select them over the PIs default. However, if I'm just using the default, I don't start jack. When i open the session in NSM, jack starts without qjackctl(or command line) and i've never had a problem with the jack connections remembered by jackpatch. However, the variable for me beyond crashing was building the NON packages on the pi instead of using the kxstudio repository. Also I now setup the kxstudio repository right after installing raspbian to use all their audio packages. I only have assumptions why everything SEEMS to play better together this way beyond non-daw crashing etc, for example my problems with debian's outdated vmpk not fitting workflows, and sid(testing) audio packages not working well together. Again beyond non-daw crashing, these are just things that happened that have too many other variables to make even good guesses about the causes, but my mileage with kxstudio all the way around has worked. I tried several setups until mine mentioned above worked where I start my pi, open an NSM session, turn on my external speaker and i'm good to go without qjackctl, unless i want to change a connection(which i also use command line for sometimes). As i was figuring out my final set of connections/apps etc with jackpatch and the several apps I tried, they all played well together after kxstudioing my audio.
