Author here. I use JACK 1 because it serves me well enough. I don't need the DBus features JACK 2 has, for example. Up until recently the recommendation was to use whichever version you want; now I just checked and the JACK authors recommend the use of JACK 2.
JACK 2 is, of course, available in Guix and has been for a long time.
Fair enough. Makes sense. Thanks for responding and for your article. I did enjoy the read. It's always good to see more stuff on FOSS music production and see how other people work.
