Reply to 4 CDJ 2000 as Aggregate Device

I'm having some difficulty getting this to work consistently. Has anyone had any success in doing this?

The problems that i seem to be facing, is that i have no idea when i make the aggregate device which cd deck is which, as they are all just listed as CDJ 2000. This is resulting in the audio signal not coming out of the desired mixer channel. Also, i'm intermittently having some of the cdj's not outputting to the mixer. The only variables i can put this down to are something to do with the way the aggregate device is created, or the usb hub that i'm using.

What i can't wrap my head around is that it should theoretically be so simple. When you enter the Advanced HID mode and select the deck for use, it should automatically route the physical output too. ie: if you select deck A on the HID then that CDJ should route out of Pioneer CDJ Aggregate device channels 0&1. This however, goes back to my lack of understanding about which order the CDJ's are created and listed in the aggregate device as a whole....

It's starting to hurt my brain...

Has anyone had more success with this than me?

Any help/advice would be gratefully received...
