Running sweet so far!
Got 64Studio all up and running now. A pleasant surprise is that it's picked up my on-board MIDI ports out of the box. Nice. That gives me the MPU midi running in jack alongside my terratec ICE1712 soundcard, but haven't got the onboard VIA8233 running with it yet. Problems with linkingqsampler/gigedit but from what I gather that's listed as a bug. Got Bristol running with -no-jack-midi. No luck getting buzztard running yet but I'll give it another bash later on. All in all, I've got to this point faster than I did when setting up UbuntuStudio. I'll put it through a few paces tomorrow and see how it performs.
