Hi rocklobster: I am in an <identical> fix! I ebayed the Mackie XD2 late last year - before realising the XP legacy driver
was all that ever came into being :-/
Having seen the apps running okay in XP Mode under Windows 7/64, I too was mortified by the lack of drivers
for any later platform. I agree that the hardware is excellent and that it's a travesty that - for want of a driver - this unit can only work as a phallic and classy basic standalone external 48 kHz souncard.
Did you manage to get anywhere with Virtual Machine cobbling of drivers to get the internal effects etc of the Spike to operate? ....... pretty-please?......
