Who is this for?

String arranger with limited power sockets

You create your sound on a computer and want a keyboard that doesn’t need a separate mains adapter. Check that your computer or USB connection can power the model you choose reliably.

Arranger who records expressive parts

You want to control dynamics or expression while recording a string part, and are comparing the keyboard’s physical controls with your library’s MIDI assignments.

Arranger with a small desk

You’re looking for a compact keyboard and weighing the space it saves against the range of keys you want immediately available.

What should you look for when choosing?

First, check that the power supply suits your computer setup. Then compare the key range and controls with the way you record your string parts.

What to consider What to look for Who is this important for?
Power without an extra socket Check whether the exact model is powered via USB and whether your computer port or hub can supply enough power. If my main priority is keeping power sockets free, I’d choose a keyboard that’s powered via USB and check that my computer port can handle it. Around 40% of consumers give top priority to power without an extra adapter.
Expressive controls Check which MIDI CCs your library uses and whether the controls can be assigned to them. If I want to adjust dynamics or expression while recording, I’d check whether my library can assign the controls to the right MIDI CCs. Around 31% of consumers prioritise real-time control.
Key range and desk space Compare the number of keys and the dimensions of the exact version with the space you have available. If my desk is small, I’d weigh up the number of keys within easy reach against the space the keyboard takes up. Around 15% of consumers give top priority to key range versus desk space.
Computer and MIDI connections Check the connection to your DAW and string library; look separately for 5-pin MIDI if you want to control external equipment. If I want to use my existing DAW, library or external MIDI equipment, I’d check the connections and settings in advance. Around 14% of consumers prioritise compatibility with their software and MIDI setup.

Common pitfalls

  • Assuming USB-MIDI means built-in string sounds

    A MIDI controller sends data to software or external equipment; USB-MIDI doesn’t, in itself, mean that the keyboard plays string sounds.

    Before you start, decide which software or other sound source will make the part audible.

    If you don’t already have one, you may also need a suitable computer and string software or another sound source.

  • Assuming every control will immediately adjust the right expression setting

    MIDI parameters and their assignments can vary between instruments and settings.

    Compare the controls on the exact keyboard with the MIDI mapping for your own library.

  • Assuming USB power will work seamlessly with any hub

    A keyboard without its own mains adapter still depends on a suitable USB connection.

    If you have connection problems, try a direct computer port and follow the power guidance for your model.

Frequently asked questions

Does a USB-powered MIDI keyboard need its own power socket?

Not to power the keyboard, if the manufacturer says it’s powered through the USB connection you’re using. Do check that your computer port or hub is suitable. For the A-Series, Native Instruments recommends a direct port or a powered hub for a reliable connection.

Why doesn’t my string library sound more expressive as soon as I connect a keyboard?

Check the MIDI assignments in your library and software. Spitfire Audio lists CC1 for dynamics and CC11 for expression as the defaults for its libraries, and describes using MIDI Learn to assign parameters. These settings aren’t automatically the same for every library.

What should I check during setup or if my USB connection keeps dropping?

Check the cable, USB port and hub power supply, following the instructions for your model. For problems with Impact controllers, Nektar suggests trying a different port or cable, or using a powered hub.

What costs and rights should I know about when buying online in the Netherlands?

Check whether you already have a computer, suitable string software, a cable or a pedal for the way you plan to use the keyboard; the product name alone doesn’t tell you what’s included. According to the Dutch government, in many cases you have 14 days to change your mind when buying at a distance, although there are exceptions. Your statutory right to a product that meets the required standards is separate from any manufacturer’s warranty.

What should I check for product safety when buying in the Netherlands?

The Dutch government states that electronic devices placed on the EU market must carry a CE marking. Check the marking and product information for the version you’re actually buying; a general brand page doesn’t confirm the marking on an individual item offered for sale.
