Connecting Midi keyboard to computer can be accomplished in several ways.
The first and most common way is to connect via Midi cable. Virtually all Midi keyboards and computers are equipped with Midi ports. Installation of drivers generally is not required.
The second method is connect using the USB port. This is a more modern connection method. Significant difference and advantage of it is the ability of power supply and Midi signal via a single USB cable. To determine the USB connection requires drivers that are supplied together with a Midi keyboard.
And finally technically obsolete connection method is by using the To Host connector and a Com port. This way is very rare due to the very low bandwidth and lack of Com-ports on modern computers.
