I have 2 usb midi controller keyboards with midi/usb outputs and I want to run them through my laptop using a vsti and send it out digitally (S/PDIF) to my m-audio projectmix to record on a second computer... i need a simple interface with preferably 2 inputs (midi/usb) for my laptop... suggestions? I suppose I could use 2 of these but there must be a better way: Behringer U-CONTROL UCA222
