With a new harddrive I'm presently considering playing with the idea of a dual Ubuntu / KX Studio for work / playwork. I primarily work with pure data and supercollider, may optionally look at other repos KX Studio has in hand.

However, my primary concern is if there are known advantages of making a slightly more complicated setup, cast against any potential install / compiling issues?

@geraldbiggs I'm not sure what the potential complications you're referring to are, but I will say that I've been using KXStudio as my primary/nearly-only environment for about two years now, and I love it. I used the ISO they provided (instead of adding repos to another flavor), which is currently Ubuntu 14.04 with KDE. Really, it's just Ubuntu with KDE... but lots of nicer, fancier audio stuff worked almost immediately (I say "almost" because this was a couple of years ago, but I don't remember any problems).
So I guess I'm wondering why you'd want a dual-boot with Ubuntu & KXStudio (if that's what you're saying), because KXStudio runs as well as any non-audio-based Linux I've used.
And PD & SC (and Reaper, under Wine, though there's also a native now) are what I usually use, too.

@Load074 Me too, my favorite app is Claudia Launcher:
