MIDI Keyboards and Controllers
The idea behind MIDI, which stands for Musical Instrument Digital Interface, was to give instruments a consistent interface to work with computers and other electronic devices. Nowadays, while you most commonly find it on keyboards, MIDI is everywhere you find music. Its come a very long way from the original eight-page version you could find in 1983.Output Matters
While the protocol supports a wide range of digital outputs, there are only two that matter to most people. DIN-out MIDI controllers use the standard five-pin DIN interface thats been around as long as the protocol. Its almost everywhere in the industry and you can always find audio equipment to support it. More recent releases have often been in the form of USB-out MIDI keyboards and controllers. While it may not be as common on musical instruments, the USB interface is otherwise ubiquitous to the point you can find it anywhere from cars to mobile phones. Most importantly, you can find it on computers, which makes editing and composing a snap.Keyboard First
Just as you dont want to use a computer without the proper keyboard, you also dont want to work with MIDI without a proper keyboard. Not only does a keyboard help get you in the right frame of mind for music, it also provides a music-specific input thats hard to replicate with other devices. With velocity sensitive keys, most let you control note volume by how hard you press the key.Keyboard Alternatives
Once you are comfortable with your keyboard, there are plenty of alternative controllers to look at. Where keyboards help you create music, controllers help you have fun with it. Many are great for performance, too. You can set up controller pads to automatically bring in pre-programmed beats whenever you want. Its perfect for DJs.Have Fun
Remember, there is always a learning curve with everything you do. Nobody is an expert the moment they first sit down at a keyboard. However, with MIDI keyboards you can not only learn to create music, but you can also master it one note at a time.
