For last night's test:
MTV -> Home receiver -> {G4 PB (Line-in) & Digital Performer} -> Pocket Drive
I'll probably also try:
Motu Traveler -> (G4 PB FW400 & Digital Performer) -> Pocket Drive
MBox -> (G4 PB USB 2.0 & PT LE) -> Pocket Drive
(2xEcho Laylas) -> Wintel DAW (Quartz, N-Track, Cakewalk) -> Pocket Drive
I suspect the bugaboos will be on how a particular recording s/w dumps to disk (big blorf or manageable stream)...
Been wanting to replace my external 3.5" with a 2.5" HD to lighten the portable rig but if all of this works out, may think more of leapfrogging and to 1.0" drives.
To be continued...
