Default USB Midi vs audio interface MIDI

Although he didn't say, his audio interface is probably also USB. It
makes no difference where MIDI data is converted to USB format - in the
keyboard itself or in the audio interface.

The one thing that might make a difference if there are a lot of USB
devices connected to the computer is whether or not using the USB output
of the keyboard will allow you to spread the MIDI data between
independent USB controllers or root hubs. If this is a Windows computer,
there's a free program called USBView that displays all of the USB
controllers and their branches. You can get a copy he

But honestly, it's probably a trivial issue with today's blazingly fast
CPUs. This was more of a concern with the 4.7 MHz 8088 PC than with one
with a 2.5 GHz or faster processor. Since it's simple enough to try both
configurations, do what's most convenient. Using the MIDI In on the
interface if it works without glitching (which it will probably do)
leaves you with one extra USB port on the computer that will eventually
get used for something.
