Start with the space you can make available and the chord voicings you want to play by hand. A smaller keyboard takes up less room, while more keys give you a wider playing range at your fingertips. Then choose controls and connections to suit the way you shape sounds and the equipment you use. A standard MIDI controller doesn’t make any sound itself, so you’ll also need to decide which software or hardware sound source to use.
You want to play ambient chords without letting the controller take over your practice area. Measure the available width and depth, then weigh them against the key size and playing range. The dimensions given for the models mentioned are from Arturia and Novation.
You want to play different chord voicings and additional notes without constantly changing octaves. Compare the number of keys, their size and the space the instrument takes up. The model details are from Novation and Arturia.
You want to adjust software or external synthesiser parameters while holding chords. Check the assignable controls and connections on the specific version, as described by Arturia and Akai Professional.
First, measure the space available for the controller and decide how many keys you want to play directly. Then check which controls and connections suit your sound source.
| What to consider | What should you check? | Who is this most important for? |
|---|---|---|
| Will the controller fit in your practice space? | Measure the available width and depth. Arturia lists the MiniLab 3 at 355 × 220 × 50 mm; Novation lists the Launchkey Mini 37 at 478 × 177 × 49 mm and the Launchkey 37 at 557 × 251 × 79 mm. Also leave room for your hands and cables. | If my practice space is small, I want the controller to fit without taking up my playing space. Around 36% of consumers prioritise a good fit. |
| Is there enough range for my chords? | Compare both the number of keys and their size; try playing your own chord voicings if possible. The models mentioned include the 25-key MiniLab 3, the 37 mini-key Launchkey Mini 37 and the 37 full-size-key Launchkey 37. | If I want to play different chord voicings without changing octaves often, having a wider playing range at my fingertips matters a lot to me. Around 29% of consumers prioritise range. |
| Can you adjust sounds as you play? | Check which controls you can assign and whether your software supports them. Arturia lists encoders and sliders for the MiniLab 3; Novation lists encoders for the Launchkey Mini 37 MK4. | If I want to shape sustained ambient sounds as I play, I look for controls that suit my software and workflow. Around 21% of consumers prioritise sound control. |
| Will the controller work with my sound source? | Compare the actual inputs and outputs on the controller and sound source. Arturia lists USB-C, MIDI-DIN and CV/Gate for the KeyStep 37 mk2; Akai Professional lists MIDI and CV/Gate connections for the MPK Mini Plus. | If I want to control an external synthesiser, the connection needs to match the device’s inputs. Around 14% of consumers make compatibility with external equipment their main concern. |
A controller sends performance data to a sound source. Akai Professional specifically confirms that the MPK Mini Plus sends MIDI messages and doesn’t produce sound itself.
Before you buy, decide which software or hardware instrument will provide the sounds and how you’ll listen to them.
If you don’t already have a suitable sound source or a way to listen, you may need to add this equipment to your setup.
A model with 37 mini keys and one with 37 full-size keys differ in key size and dimensions. For example, Novation lists different body dimensions for the Launchkey Mini 37 MK4 and the Launchkey 37 MK4.
Measure your playing space and, if you can, try your own chords on the key size you’re considering.
Your equipment needs to support the connection you choose. The KeyStep 37 mk2’s connections will only work in a setup that’s compatible with them.
Compare the inputs and outputs on the controller and sound source, and check what power supply and cables your setup needs.
A hybrid setup may require suitable cables, a power supply or additional equipment.
The Launchkey Mini 37 MK4 combines 37 mini keys with software controls, while the Launchkey 37 MK4 has full-size keys.
The MiniLab 3 is a compact 25-key controller; the KeyStep 37 mk2 is designed for a 37-key setup, with connections and sequencing features.
The MPK Mini Plus is an option for a setup with 37 mini keys, pads and connections for external equipment.
The Oxygen Pro Mini is an alternative with 32 keys and controls aimed at software production.
Yes. You’ll need a suitable software or hardware sound source and a way to listen to its audio. Akai Professional specifically confirms that the MPK Mini Plus sends MIDI messages and doesn’t make sound itself.
Check that the USB connection and music software are compatible with your computer, then select the controller as a MIDI input in the software if needed. Some models may require additional setup for features such as chord controls and parameter controls, depending on your DAW.
Yes, if your synthesiser has a suitable connection and you have the required power supply. Arturia lists MIDI-DIN, USB-C and CV/Gate for the KeyStep 37 mk2; check which input your synthesiser uses. The controller still won’t act as a sound source itself.
For an eligible online consumer purchase, you generally have up to 14 days after delivery to change your mind, according to ACM ConsuWijzer; exceptions may apply. You’re also entitled to a product that’s fit for purpose. The Dutch government explains that there is no fixed, general statutory warranty period in the Netherlands.
A CE marking is required when the specific product is covered by EU rules that require it. Check which requirements apply to the controller you choose and any power supply included; a CE marking in itself does not certify playing quality under European Union rules.
