New to Max, and haven't tested it with my firebox until now. The strange thing is that the Firebox shows up in the driver list, the input device list, as well as listing the correct amount of input and output channels, but the rest of the options are blanked out! Nothing on input source, nothing on output destination! Why? Is there some kind of fundamental incompatibility between Firebox and MaxMSP that is not present with any other DAW around? Have been using this soundcard for at least three years now with all other applications, and I find it hard to believe that Max should be this peculiar....
