Anybody have any trouble trying to run more than one midi keyboard via usb. I can't seem to use two at the same time(I'm using a Oxygen 8 and a Radium 49). I tried running them thru a usb hub and then thru each usb slot on my Powerbook G4. In the prefernce menu under midi it only says "USB Port 1" So i tried running the 2 thru a usb hub into that port and it did not work. Please help me out thanks.
