For recording chords on a computer, a USB-powered MIDI controller is a sensible choice if you don’t want to use a separate mains adapter for the keyboard. Just check that your computer can power the controller through the connection you plan to use. Then choose a compact keyboard with chord functions if you want to enter ideas quickly, or more keys if you prefer to play chord voicings yourself. Also check that your DAW can record MIDI and has an instrument to make the notes audible.
If you record chords using a laptop, look for USB power to avoid needing a separate mains adapter for the keyboard. Your computer must be able to power the controller through the connection you plan to use. Arturia, M-Audio and Roland describe USB-powered models.
A compact keyboard with model-specific chord functions could be a good fit if you want to enter short progressions. Check how the function works on your chosen model and which notes your DAW records. Novation, Arturia and M-Audio describe different chord functions.
If you prefer to play chords across a wider range yourself, 49 full-size keys may be more appealing than mini keys. Bear in mind how much desk space you’ll need; Roland and Nektar describe models with 49 full-size keys.
First, check whether your computer can power the controller via USB. Then choose between a wider key range and a chord function, depending on how you want to play.
| What to consider | What should you check? | Who is this important for? |
|---|---|---|
| USB power | Check that the exact model gets both power and a MIDI connection to your computer via USB. For the MiniLab 3, Arturia recommends using a hub with Power Delivery or its own power supply, if possible. | If I don’t want to use an extra socket for the keyboard, I check that my computer or chosen hub can power it. Around 33% of consumers rank USB power as their top purchasing priority. |
| Key range and size | Compare mini keys with full-size keys and consider how much space the keyboard takes up. The examples mentioned range from 37 mini keys to 49 full-size keys. | I want to play my own chord voicings and have enough keys within reach without constantly changing octaves. For around 27% of consumers, playing range comes first. |
| Chord functions | Compare the chord mode on the specific model and check which MIDI notes it sends to your DAW. Novation, Arturia and M-Audio describe different functions. | If I want to enter chord ideas quickly, how the chord function works matters more than having a larger keyboard. Chord input is the top priority for around 27% of consumers. |
| DAW and sound source | Check that your DAW receives MIDI input, that a track is ready to record, and that a software instrument or suitable external sound source is available. | I want to set up and listen back to my MIDI recording easily, not just enter notes. Around 13% of consumers rank DAW recording and setup as their top priority. |
A USB connection for MIDI doesn’t automatically mean that the controller will work without a separate power supply in every setup. The computer’s or hub’s connection and power capabilities also matter.
Check whether USB provides both the required power and MIDI connection for the exact model. For the MiniLab 3, Arturia recommends using Power Delivery or its own power supply with a hub, if possible.
MIDI contains note information, not recorded sound. You won’t hear the notes you play unless you have a suitable software instrument or external sound source.
Check the MIDI input, recording or monitoring track, instrument and audio output in your DAW.
Novation, Arturia and M-Audio describe different chord functions and settings. The name of a function alone won’t tell you whether it suits the way you want to play and record.
Check how the function works on the exact model and which notes are recorded in your DAW.
The product ranges mentioned differ in key size, chord functions and connections, among other things. Check the specifications of the exact model and make sure it works with your DAW.
Novation says the Launchkey Mini 37 MK4 has 37 mini keys and chord modes for use with a DAW.
Arturia says the MiniLab 3 combines 25 velocity-sensitive keys with a chord mode and USB power.
M-Audio says the Oxygen Pro Mini is a USB-powered controller with 32 mini keys and Smart Chord.
Roland describes the A-49 as a MIDI keyboard with 49 full-size, velocity-sensitive keys and power from a computer’s USB bus.
Nektar says the SE49 has 49 full-size, velocity-sensitive keys and DAW controls.
Not for the keyboard, provided the specified USB bus power works through a suitable computer connection. Check the power requirements and connection for the exact model; the computer or powered hub will still need its own power.
MIDI notes aren’t a sound recording. Check the MIDI input, recording or monitoring track, a software instrument and the audio output in your DAW. Ableton explains MIDI input and arming tracks separately.
First, check whether you can connect the controller directly. For the MiniLab 3, Arturia recommends using a hub with Power Delivery or its own power supply, if possible. This is advice for this model, not a guarantee that every hub will work.
In many cases, online distance purchases from a business come with a 14-day cooling-off period. The rules may differ, for example, if you buy from a private seller. Check who the seller is and what returns information they provide. The Dutch government’s Rijksoverheid explains this cooling-off period for distance purchases.
Relevant European requirements apply to electrical and electronic equipment, including rules on electromagnetic compatibility. According to Business.gov.nl and the European Union, CE marking and an EU Declaration of Conformity are required when the applicable harmonised rules stipulate this; this doesn’t automatically apply to every electrical product.
