I've submitted official bug reports.. is anyone working on this or am I wasting my time and should discconnect it from the parallel port and just connect via multiple usb MIDI interfaces into the mtpav rack? (I can't actually swap for an m-audio or edirol as they don't have the routing capabilities...such as eliminating clock sources from individual ports e.t.c.)
