So... even if the 660 has a USB connection and drivers, to connect to a computer.... and many keyboards have those these days.... it's for the purpose of getting midi to the computer. Just like serial ports on computers, 5 pin midi jacks are going away in favor of the USB connection.

The keyboard may or may not have a built in interface. Without reading the specs, I don't know. But I'd be willing to wager it probably doesn't. And not a full featured one if it does have one. HOWEVER.... even if it does, I would not use it for recording and running the software for a DAW. How would you connect external reference monitors and condenser mics for recording and monitoring other source material?

You should still look into having a dedicated and preferably external recording interface.

You can still easily get the midi into that interface through software and selecting the proper inputs to the tracks. That's what the USB is for on the keyboard. And again.... that interface should run ASIO.

The magic you are looking for is in the work you are avoiding.
