Inspired by this thread - https://forums.freebsd.org/threads/is-there-any-dac-compatible-with-freebsd.74463 I finally got around to test if my old Roland Tri-Capture usb sound device could work with FreeBSD15.
As it turned out it was a no go. The Roland was identified but since it needs drivers on both PC and Mac and there is no driver for FreeBSD I borrowed a Focusrite Scarlett 2i2 to see what it could do.
After plugging in the Focusrite and installing audio/jackit and audio/qtractor and changing
I start (as user) jack with
And Qtractor works just fine. I added an old MIDI keyboard with a cheap MIDI to USB plug and apart from having to connect the MIDI interface inside Qtractor to the Qtractor output everything works fine.
When I record guitar there is no noticeable latency. I can record tracks simoultaneously.
It's really great, especially since the computer is an old laptop from 2014-2015.
I added some plugins and I noticed Guitarix not firing up the GUI. I also noted that if I exit jack before exiting Qtractor then will not shut down "jackdbus auto" unless I kill -9 it.

1. Does anyone know how to make the Guitarix lv2 plugins work in Qtractor. It feels like it should fire a gui when added to a track?
2. Is there a better or more clever way to run jack and Qtractor? I have tried Qjackctl and virtual_oss but Qjackctl gets confused by Qtractor not closing jackdbus auto.
