FR: unify yamaha/steinberg driver

im still wishing for some kind of ASIO 3 driver which has no latency and accepts all connected audio cards to be used in DAW.
but at least for near future a yamaha/steinberg driver that can use all connected steinberg and yamaha hardware in cubase could be great
so both my MR816+my ur44+my yamaha keyboard with usb audio interface, can be used simultaneously and identified by Asio driver and cubase.
i heard MUTU,and UA audio interfaces driver can do it
