MIDI KEYBOARD CONTROLLER
A keyboard that sends note, velocity and controller data rather than making sound. Key count, key feel, pads and knob count are the only real differences.

Key takeaways
- A keyboard that sends note, velocity and controller data rather than making sound.
- Key count, key feel, pads and knob count are the only real differences.
- Key count decides what you can physically play — 25 keys for sketching, 49 for two-hand parts, 61 for anything piano-like — and the rest of the spec sheet is pads, knobs, faders and whether it is USB-powered.
- A 25-key controller plus a laptop covers 90 percent of beat-making; a 61-key semi-weighted board is what you want if you actually play chords with both hands.
- Watch out: buying more keys than your desk fits.

MIDI KEYBOARD CONTROLLER IN DEPTH
A MIDI keyboard sends note, velocity, pitch bend and controller data; the sound comes from whatever it drives. Key count decides what you can physically play — 25 keys for sketching, 49 for two-hand parts, 61 for anything piano-like — and the rest of the spec sheet is pads, knobs, faders and whether it is USB-powered.
How it works in practice
A 25-key controller plus a laptop covers 90 percent of beat-making; a 61-key semi-weighted board is what you want if you actually play chords with both hands.
The mistake people make
Buying more keys than your desk fits. A controller stored in a cupboard sends no MIDI at all.
