If desk space is limited, a 25-key model is the more compact option. Choose 37 keys if you want more keys within easy reach and have room for them. Chord, hold and control functions vary by model, so check that they work with your DAW or external instrument.
You’re looking for a controller that fits next to your computer and are happy to switch octaves to save space. The dimensions of the SE25 and MiniLab 3 show why depth matters as well as the number of keys. Nektar and Arturia publish the dimensions of these models.
You want to play chords directly or build them using chord functions, while adjusting parameters during long, sustained notes. Models vary in key range and controls: Novation, Arturia and Akai Professional describe chord functions for specific models, among other features.
You want to check whether a compact controller can control your external equipment directly. Arturia lists MIDI DIN and CV/Gate for the KeyStep 37 mk2; check that these connections are compatible with your equipment.
Choose this if: your desk has limited space and you mainly play chords one at a time.
Bear in mind: a smaller key range may mean switching octaves more often.
Choose this if: you want more keys within easy reach but still need a compact controller.
Bear in mind: measure the available width and depth; mini keys are not full-size keys.
Choose this if: you want to control equipment as well as software, using MIDI DIN or, with a compatible modular setup, CV/Gate.
Bear in mind: connections and the sequencer are only useful if they suit your equipment and workflow.
| Consideration | What to look for | Who it matters to |
|---|---|---|
| Desk space | Measure the available width and depth, including room for connections. Compare the dimensions of the exact model. | I need to fit the controller on a small desk first, so I check its full dimensions. Around 36% of consumers put space at the top of their list of buying concerns. |
| Range for playing chords | Compare 25 with 37 keys, and check what the chord and hold functions do on the exact model. | If I want to play chords without constantly switching octaves, I look at both the key range and the chord function. For around 29% of consumers, playing range comes first. |
| Sound control | Look at the controls on the device and check compatibility with your DAW and plug-ins. | When playing long, sustained notes, I want to adjust parameters without constantly reaching for the mouse. Direct control is the top buying concern for around 21% of consumers. |
| External connections | Make a note of the inputs on your instruments and compare them with the connections on the exact model. | I need to control my existing synthesisers directly, so I compare their connections with those on the controller first. Around 14% of consumers prioritise external equipment. |
Two 25-key controllers can differ in depth and in the controls they offer.
Measure the available width and depth, then compare the key range and controls on the exact model.
A function’s name doesn’t tell you how to trigger, hold or change chords, or how the function works with your DAW.
Check the manual for your chosen model to see how its chord controls work, and test them with your software.
Arturia lists MIDI DIN and CV/Gate among the connections on the KeyStep 37 mk2, but not every external setup uses the same connections.
Compare the controller’s outputs with your instrument’s inputs and requirements. Depending on your setup, you may need suitable cables or an additional interface.
The Launchkey Mini 37 MK4 offers a 37-key option with chord functions and DAW controls.
The MiniLab 3 is a compact software controller, while the KeyStep 37 mk2 also caters for sequencing and connections to external equipment.
The MPK Mini IV is a compact alternative with keys, pads and built-in scale and chord functions.
The SE25 is an option if a shallow footprint matters more than extensive onboard controls.
This Joybuy selection includes a 61-key keyboard and MIDI controller. If desk space is limited, it’s worth measuring the space available and checking whether the wider playing range suits your setup.

This model may suit you if a wider playing range matters more than a compact design; the product name specifies 61 keys and a MIDI controller.
Before buying, check the dimensions and connections for your workspace and equipment.
A MIDI controller sends MIDI data to music software or a connected instrument. Decide in advance where you want the sound to come from and which connection your setup uses for it.
That depends on the model and your software settings. Arturia lists hold and eight encoders for the MiniLab 3; check which parameters the encoders control in your DAW or instrument plug-in.
Check that your computer or DAW recognises the MIDI input and that software integration is set up for your model. Follow the documentation for the exact model for installation and updates. For example, Nektar states that additional DAW integration for the SE25 requires registration and a download.
