A MIDI controller sends notes and control data to your music software; it makes no sound itself. For most producers, a 25 to 49-key controller with velocity-sensitive keys, pads for drums and a few assignable knobs is the sweet spot. Choose 61 or 88 keys if you play two-handed parts, and check that it integrates with your DAW.
A MIDI controller turns your music software into an instrument you can play. Here is what to look for.
Keys
| Keys | Good for |
|---|---|
| 25 | Beats, basslines, small desks, travel |
| 37 | Slightly more range for melodies |
| 49 | Two-handed chords and parts |
| 61 | Keyboard players, synth parts |
| 88 | Piano parts and piano practice |
Key action: synth-action keys are light and fast; semi-weighted add some resistance; fully weighted mimic a piano. Mini keys save space but are harder for two-handed playing.
Pads
Velocity-sensitive pads are essential for finger drumming and triggering samples. Look for:
- Size and feel: larger pads with good response are easier to play.
- Aftertouch for expressive control.
- Note repeat and multiple pad banks.
Knobs, faders and buttons
Assignable knobs and faders let you control filters, effects and mixer levels hands-on. Transport buttons (play, stop, record) save trips to the mouse.
DAW integration
Many controllers include scripts that automatically map controls to popular DAWs. This is the biggest difference between a controller you love and one you fight with. Check compatibility with your software.
Other features
- Pitch and mod wheels or touch strips for expression.
- Sustain pedal input for piano parts.
- USB-C bus power for a simple, single-cable setup.
- 5-pin MIDI out if you want to control hardware synths.
- Bundled software, often including instruments and a light DAW.
Quick picks
- Beat maker: 25 keys plus 16 pads.
- Producer and songwriter: 49 keys, pads, knobs and DAW integration.
- Keyboard player: 61 or 88 semi-weighted or weighted keys.
Common questions
Does a MIDI controller make sound?
No. A MIDI controller sends note and control information to software or hardware instruments, which produce the sound.
How many keys do I need on a MIDI controller?
25 keys for beats and basic melodies, 49 for two-handed chords and bass lines, 61 or 88 if you play piano parts.
Do I need pads on a MIDI controller?
If you make beats or trigger samples, yes. Velocity-sensitive pads are much easier for drums than keys.
