I have been trying to complete a Protools studio for over a year now. So far I have the Mix Core and Farm Cards an 888 24 I/O on a G4 Quicksilver running OSX .4 and Protools 6.1. I have a 7 slot SBS expansion chassis . Since I upgraded to OSX Tiger and 6.1 they program won't load because it says it can't find the hardware. Now I just purchased the M-audio M-Powered software and 192 Audiophile sound card interface. I'm in the process of getting the Digidesign command 8 ASAP. Am I finally going to be able to get this system up and running after this or what? It seems that every time I think I have everything I need, I still need something else and I'm wondering when it's going to end.
