The AUDIOBOX ITWO has the USB "Device" port on the back. I've successfully connected that to an iPad for Garageband.
When I take a Yahama keyboard with a USB interface I can connect the keyboard directly to the USB port of a Mac and get great Garageband MIDI connectivity.
When I have the AUDIOBOX ITWO connected successfully to the Mac and Garageband with the standard host port on the AUDIOBOX ITWO can I then connect the Yahama keyboard to the Device port of the AUDIOBOX ITWO and also see it via Garageband Mac? Seems like that should be doable and would be great. It'd allow a non-alalog connection and full connectivity without having to plug the keyboard into the Mac via a different USB port.
I guess I assumed this would be possible or otherwise I might not have gone with this box.
