Desktop computer users, too, will often require a dedicated MIDI interface instead of a sound card gameport-MIDI connection. The use of a dual, or multi port interface will give the user total control over each instrument and virtually eliminate MIDI timing errors in a multiple instrument setup. This is mainly because of their ease of installation and portability. Many music pastors, for example, work with two computer systems between home and office. They need only purchase one external interface for the two systems, because they can easily disconnect and connect the interface to either system.
Initial installation is a breeze.
You just install the MIDI driver for the interface and plug the interface cable into the computer s printer or USB port, and you are ready to go. The illustration below is an example of an external MIDI interface that connects to your computer via a USB port. External interfaces come as single, dual, and multi port configurations. The diagram layout is the same when using a USB external interface. Keep this list with you as you begin installation of your MIDI interface.
