Hi guys, any news on the situation regarding using (aggregating) multiple input devices? I'm running 6.1.3 iOS on an iPad2. With a 3rd party cck and a powered hub I can get stable operation from my Lexicon Omega recording all four tracks simultaneously. I can also get stable operation with my Zoom H2n (needs to be added to your list!), recording two tracks simultaneously. But if I plug them both in... I generally get only the second device. It would be really good to aggregate them together. How about it? Btw if I plug the two in while I'm in garage band the app quits!!

I recommend getting an actual CCK.
I can run multiple input devices using a powered usb hub, but am using a real Apple CCK.
I'm currently running an Akai EWI USB and a Yeti mic into the hub.
When using Audiobus, I get the mic as an input and any synths that are running all at the same time.

I just found out that the idevices assume that the "last" device (mic/interface) plugged in is the intended device to use.
