MIDI Keyboard Buying Guide

As the name implies, it is a keyboard that controls MIDI data.  MIDI data can be sent to an outboard synthesizer / module and to a computer hosting virtual instruments.  A MIDI controller keyboard does not contain in-built sounds (unless it says so on the box), it is simply used to trigger the sounds in your sound source, i.e. virtual synthesizer.

In the old days MIDI keyboards had just a MIDI connection, a socket for a sustain pedal, and a plug hole for a power supply.  I’ve always had enough plugs switched on in my studio (4-way extension cables galore) and I was delighted when the USB technology got introduced to MIDI controllers.  Not only does the keyboard send MIDI data through USB, it also powers the keyboard.  This is particularly useful when playing live – one less cable and one less power plug. The data sent down a USB lead is quick so you never really need to use your MIDI out unless you’re using it to control an external synth or module.  Some heavy duty 88-note keyboards do still need a power supply, but most run just off USB.

MIDI is still a very powerful tool, with knobs, faders, keys and pads being able to control many software parameters.  If you are looking for a controller keyboard to be your main keyboard, it’s worth looking at something with plenty of knobs and faders.  If you are also doing beat production or sample triggering a controller with pads on will come in very useful.  Most larger keyboards include a pitch bend wheel and modulation wheel (sometimes both on the same joystick), which can create interesting effects.

This depends on what you are looking to achieve – a small 25 note controller keyboard is small and portable, however you won’t be able to play classical masterpieces on it, even with the Octave Up / Down button.   A 49 or 61 key MIDI controller keyboard feels more natural to a player, and most 88 note keyboards have the realistic piano hammer action keys.  Choose the right keyboard for your setup.
