Aggregation might also work, you can try it. If it works you should be able to do what you want. If the devices actually aggregate (does a 003 actually aggregate at all?) then what is happening? What IO paths show up... if things don't look right then try defaulting the IO (deleting all the paths and then click "Default" on the Setup>IO>input/output/bus pages). If they still don't look right just go in and manually name all the IO to whatever you want.

Get pre-recorded audio playing back out the outputs you want. Then worry about getting monitoring to work -- and if it is not then I expect you have Pro Tools in the wrong input monitoring mode.

...But aggregation tends to be buggy even if it works at all, and more so when trying to combine USB and Firewire interfaces. Personally I'd not waste time trying it. Worse case, swapping a few cables is not a huge amount of work.

The other question is why just record analog elsewhere in the signal path, wether DI and/or micing a cab.

Thanks Darryl. Mac was restored to previous backup, and I've abandoned USB audio. Just a few swaps of patches and all is good.

Thanks!
