Choose a MIDI controller based on the controls you want to use to shape your lead, and the connections available on your software instrument or hardware synth. A compact keyboard takes up less space, while a larger one puts more keys within easy reach. Aftertouch is only useful if the sound source supports the relevant messages. MIDI sends performance data, not audio, so you’ll also need a sound source and audio output, as the MIDI Association explains.
Wants to use pitch, modulation or pressure while playing to change the lead sound. What’s possible also depends on the synth being controlled. The MIDI Association describes MIDI as carrying data for things such as notes and controls; product specifications from Native Instruments and Arturia also distinguish between aftertouch on keys and on pads.
Wants to control an existing synth directly and needs to match the MIDI connection, power supply and supported messages. Arturia and Novation describe different connection options for their specific models.
Wants a keyboard that fits the available space and is weighing up compactness against the number and size of the keys. Novation’s product specifications, for example, show the difference between a Mini 37 with mini keys and a Launchkey 49 MK4.
For a synth lead in a loft, your choice mainly comes down to expressive controls, compatible connections, available playing space and a complete audio chain.
| Consideration | What to check before buying | Who is this important for? |
|---|---|---|
| Expressive controls | Check which controls the exact model has and whether your synth can receive and assign the MIDI messages you want. | If I want to shape the lead while playing using pitch bend, modulation or pressure, I check whether my sound source responds to them. Around 36% of consumers prioritise expressive lead control. |
| Connecting to a synth | Compare the controller’s output with your synth’s input; also check the cable, power supply and supported messages. | If you want to control a hardware synth directly, you mainly need a compatible connection. Around 29% of consumers give priority to connecting to hardware. |
| Keyboard size and space | Measure the available space and check the number and size of the keys. | If my playing space is limited, I weigh up smaller keys and less immediate reach against the space taken up by a larger keyboard. Around 21% of consumers prioritise playing space. |
| Sound source and listening | Decide where the sound will come from and how you’ll listen to it; also check the rules and agreements that apply to your home. | When I want to work out how to make the lead audible and listen to it in the loft, I consider the whole audio chain. Around 14% of consumers prioritise their sound setup. |
Aftertouch on the Launchkey 49 MK4’s pads is not the same as aftertouch on its keys. Check which controls the feature works on and whether your instrument processes the relevant message.
The Keystation 49 MK3 uses USB-MIDI; M-Audio lists a 5-pin MIDI output as an additional feature of the Keystation 61 MK3. Compare the connections on the exact model with your synth’s input.
MIDI carries performance and control data, not an audio signal. Decide in advance which software or hardware will produce the sound and how you’ll listen to it. Depending on your existing setup, you may need additional equipment or software.
Offers models for both compact software setups and larger keyboards with hands-on controls.
The KeyStep 37 mk2 is a compact option for compatible hardware or modular setups; the KeyLab 49 mk3 is a separate model with a larger keyboard.
According to Akai Professional, the MPK Mini Plus combines a compact keyboard with controls for software and external equipment.
The Kontrol S49 MK3 is designed for players who want to use a larger keyboard with polyphonic aftertouch alongside supported software.
The Keystation 49 MK3 is a straightforward option if you’re looking for a full-size USB-MIDI keyboard with conventional pitch and modulation controls.
This selection includes 61-key keyboards for anyone looking for a wider range of keys at their fingertips. Before buying, check that the MIDI connection and operation of the exact model suit your synth lead setup.

No. A MIDI controller sends performance and control data. Connect it to a suitable software or hardware sound source and arrange audio output from that source to hear the sound.
First check whether the synth has a compatible MIDI input. Novation says a Launchkey MK4 can send data via its MIDI output when powered over USB; also check the cable and the synth’s MIDI settings.
No. Check which parts of the exact model support aftertouch. For example, the polyphonic aftertouch on the Kontrol S49 MK3’s keyboard differs from aftertouch on the Launchkey 49 MK4’s pads. Your instrument must also support the relevant messages.
That depends on the rules and agreements that apply to your address. The Dutch government recommends agreeing on arrangements with your neighbours first if there’s a noise nuisance; also check any tenancy or owners’ association agreements.
For a distance purchase from a professional seller, you generally have a 14-day right to cancel from the day the goods are delivered. Check the relevant exceptions and any return costs disclosed in advance; this is separate from your statutory rights if the product is faulty.
Check that the keys and controls are sending the intended MIDI messages to the correct input. For the KeyStep 37 mk2, Arturia describes checking and updating the firmware via MIDI Control Center; for other models, follow the manual for that exact model.
