Just out of curiosity, can anyone confirm what the exact differences are
between Trisquel 7 and Trisquel-Mini 7? Is it just swapping the GNOME desktop
for the LXDE? Are there any other changes made to Mini? If not, then
installing LXDE on a normal Trisquel 7 system would allow you to switch back
and forth between your LXDE audio production system and a full Trisquel
desktop (maybe with a separate user for each).
Better still you could pick an even more lightweight desktop than LXDE, one
that isn't being discontinued in favour of its successor LXQT:

I've used OpenBox as a way to scrape a bit more performance out of my poor
little netbook when I try to make it run games. Maybe that could be an option
for audio production?
Have you tried any of the desktops based on the Enlightenment window manager
and the Enlightenment Foundation Libraries? I'm not aware of any 100% libre
GNU-Linux distros that offer an Enlightenment flavour, which is a shame,
because a properly integrated and tested version would have amazing
bang-for-buck on legacy hardware (or any hardware).
BTW Have you ever tested Musix? It would be great to have a flagship libre
music production distro that had the resources to stay up-to-date with new
releases of its base distro and the apps it uses. I wonder what could be done
to facilitate that?
