Do you need an interface for a MIDI keyboard?

What sort of interface do you need? A MIDI keyboard does not need an audio interface to connect to a computer. It needs either a separate MIDI interface, or some keyboards can connect via USB. Some audio interfaces do include MIDI, and these dual-purpose interfaces can be used to connect a MIDI keyboard to a computer.
