MIDI Keyboard Controllers

A MIDI keyboard controller has no internal sound at all — its sole function is sending MIDI data (which note was pressed, how hard, etc.) to software on a computer, which then generates sound via a virtual instrument/plugin. A regular keyboard has its own internal sounds and doesn't need a computer.

Most MIDI controllers use the standard USB MIDI class-compliant protocol, which is compatible with nearly all popular DAWs like Ableton Live, FL Studio, Logic Pro, and Cubase, on both Windows and Mac.

For simply controlling virtual instruments and listening through your computer's speakers/headphones, it's not required. But for the best monitoring quality and lowest latency in serious production work, an additional audio interface is highly recommended (see the Home Studio & Recording collection).

It depends on your needs — 25-32 keys suit high mobility and simple beat production, 49-61 keys balance portability with note range, while 88 keys suit those who want a full piano-playing experience while producing music.

Yes, especially when connected to a laptop running live performance software or synth plugins — assignable pads/knobs on some models also help with real-time control during a show.
