A MIDI keyboard controls a software instrument or external synthesiser, but won’t produce audible sound on its own. First, choose your sound source and check that the connections and power supply are compatible. Then compare the key size, playing range and pitch and modulation controls for your synth lead. Product specifications can help you compare these features, but they don’t replace a comparative playing test.
You play the melody yourself and want to control pitch and modulation as you play, so key size and easy access to the playing range are important to you. Novation describes the pitch and modulation controls on the Launchkey 37 MK4; Arturia uses touch strips on the KeyStep 37 mk2.
You already have an external sound source and are mainly looking for compatible MIDI connections, power and controls. Check the connections on both the controller and your synthesiser.
You use a computer to generate the sound and want the controller, software instrument and audio output ready for rehearsal. Novation notes that MIDI control data itself contains no sound.
Choose this option: if a computer running compatible software provides the sound.
Bear in mind: the controller sends MIDI data, so you’ll also need to set up the instrument and audio output.
Choose this option: if you’re using an existing hardware synth as your sound source.
Bear in mind: the MIDI output, synth input and power supply must be compatible; a MIDI connection won’t produce sound on its own.
| What to consider | What should you check? | Who is it important for? |
|---|---|---|
| Playing range and expressive controls | Compare the key size, number of keys, and pitch and modulation controls on the exact model. | If I’m playing a lead part, I want the notes and expressive controls I need close to hand. Around 36% of consumers give playing range and expression top priority. |
| Connection to a hardware synth | Check the controller’s MIDI output, the synth’s input and how the controller is powered. | If you already have an external sound source, you’ll want to make sure the devices can communicate directly. For around 29% of consumers, this hardware connection comes first. |
| Software and audio chain | Check that the software receives MIDI, loads the instrument you want and sends audio to the right output. | If you use a computer for your synth sound, you’ll want both MIDI and audio output to work during rehearsal. This is the main concern for around 21% of consumers. |
| Space and portability | Measure the available space and check the key size on the exact model variant. | If you have limited space or need to take the keyboard with you, a compact model may be more practical. However, smaller keys feel different from full-size keys. Around 14% of consumers prioritise space and portability. |
Novation explains that MIDI control data contains no sound. So, without a software instrument or external sound source, you won’t hear a synth sound.
Before you buy, work out where the sound will come from and how you’ll play it in the rehearsal room.
For software sounds, you’ll also need a compatible instrument and working audio output. If you’re using hardware, the synth itself must produce the sound.
These are different connection options. Arturia lists MIDI DIN, USB-C and CV/Gate for the KeyStep 37 mk2; Novation describes using a separate MIDI cable and USB power for the Launchkey MK4 with hardware.
Compare the connections on the exact controller with the inputs on your sound source, and check how the controller is powered.
Depending on the equipment you already have, you may need a suitable cable or interface. Check before connecting your setup.
The same number of keys doesn’t mean they’re the same size. Akai lists 37 mini keys for the MPK Mini Plus; Novation lists 37 full-size keys for the Launchkey 37 MK4.
Check the full model name, key size, playing range, and pitch and modulation controls.
Novation describes the Launchkey 37 MK4 as having full-size keys, pitch and modulation wheels, and controls for supported music software. The manual also lists a five-pin MIDI output.
Arturia describes the KeyStep 37 mk2 as a compact controller with Slimkey keys, touch strips, a sequencer, and MIDI DIN, USB-C and CV/Gate connections.
Akai lists 37 mini keys, separate pitch and modulation wheels, pads, a sequencer, and MIDI and CV/Gate connections for the MPK Mini Plus.
Roland describes the A-49 as having 49 full-size, velocity-sensitive keys.
This product selection is suited to playing parts yourself on a keyboard with MIDI controller functionality for use with a software synth.

The listed MIDI controller functionality makes this model worth considering if you’re looking for a keyboard to play parts yourself and send MIDI to software.
61 keys; MIDI controller functionality.
A MIDI controller sends control data, not audio. Choose a software instrument or connect an external sound source. If you’re using software, also check that the audio output is set up correctly. Novation makes the same distinction for the Launchkey.
Yes, as long as the controller’s connections and power supply are compatible with your synthesiser’s input. Novation describes a setup for the Launchkey MK4 using USB power and a separate MIDI cable to connect to hardware; the controller doesn’t produce sound itself.
Check that the power and MIDI connections work, that the instrument receives the notes you play, and that audio is sent to the right output. Test the controls you plan to use during your lead part too. For example, Novation lists separate pitch and modulation wheels on the Launchkey 37 MK4.
According to the Dutch government, when you buy from a business at a distance, you’ll often have a 14-day cooling-off period. Exceptions and the seller’s circumstances may be relevant. Faulty products are covered by the statutory guarantee. The Dutch government notes that the Netherlands doesn’t have one fixed statutory guarantee period for all products.
No. According to the European Union, CE marking is required when the applicable harmonised product rules say it is, and the manufacturer is responsible for compliance. A CE mark on its own isn’t an independent playing or safety test report for a specific item.
