Who is this buying guide for?

String arranger who plays in expressive parts

Wants to shape dynamics and expression while playing, and to check whether their string library can learn or assign MIDI controls. Spitfire describes CC1 for dynamics and CC11 for expression among the controls used by its libraries.

Producer with a cramped desk

Needs to fit a controller alongside a computer and mouse, so compares both the width and depth of its casing.

Arranger who plays in phrases

Wants enough keys to play melodies and chords, and is weighing up a 37-key keyboard against a more compact 25-key model.

What should you look for?

Start with the dimensions of your desk and the number of keys you need to use at once. Then check MIDI mapping and software compatibility.

What to consider What to look for when buying Who is this most important for?
Dynamics and expression Check whether your library has MIDI Learn features and whether you can assign the control you want to the right parameter. If I want to adjust dynamics and expression as I play, I need to be able to control the right parameter directly. Around 33% of consumers give expression control top priority.
Desk space Compare the stated width and depth with the space available, and allow room for cables and your hands too. If my desk also needs to fit a computer and mouse, I want to know whether the whole casing will fit. Around 27% of consumers put available desk space first.
Number of keys Compare 25 and 37 keys to find the range you need to play at once. Arturia, Novation and Akai list models with 37 keys; Arturia lists the MiniLab 3 as having 25 keys. When I want to play in phrases and chords without constantly changing octaves, having the right range at my fingertips matters. Around 27% of consumers give this range top priority.
Software and connections Check that the controller works with your computer and DAW, and that any pedal input supports the pedal type and function you need. If my existing software and connections are the deciding factors, I want to know in advance which controls will work straight away and which I’ll need to set up. Around 13% of consumers prioritise their software workflow.

Buying pitfalls

  • Measuring width only

    A controller may fit across your desk but still be too deep for the space beside your computer or mouse.

    Measure both the available width and depth, and leave extra room for cables and your hands.

  • Assuming a modulation wheel or slider will automatically control the right expression setting for strings

    In the libraries described by Spitfire, CC1 and CC11 have different functions. You need to assign a physical control to the appropriate MIDI parameter.

    Check your own library’s settings and test the mapping before buying an extra controller or pedal.

    Setting up MIDI mappings takes time. If you don’t already have the string sounds you want, check which software or library you’ll need.

  • Choosing a sustain pedal for expression without checking the connection

    An input may support different functions on a particular controller, and the connection and pedal plug also need to be compatible.

    Check the function, input and plug type for the exact controller and pedal combination.

    An incompatible pedal may mean you need to buy another one.

Relevant brands to consider

Arturia

According to Arturia, the MiniLab 37 has 37 slim keys and four sliders, while the MiniLab 3 has 25 keys and four sliders.

  • Arturia lists one assignable input on the MiniLab 37 for sustain, expression or a footswitch.
  • Check the MIDI mapping, and don’t assume that you can use two pedal functions at once through that single input.

Novation

The Launchkey Mini 37 MK4 combines a 37-key keyboard with touch strips, encoders, pads and DAW controls.

  • Novation lists dimensions of 478 × 177 × 49 mm and two touch strips for pitch and modulation.
  • Novation distinguishes between sustain pedals with a TS connection and TRS damper pedals. Check the pedal type, and don’t assume a sustain input will support expression unless this is confirmed.

Korg

The microKEY2-37 is a USB-powered controller with 37 mini keys and a modulation wheel.

  • Korg gives the microKEY2-37 dimensions of 565 × 139 × 54 mm. Its shallow depth could be useful if depth is the limiting factor on your desk.
  • It is wider than the Launchkey Mini 37, and Korg lists an assignable switch input rather than a set of sliders.

Akai Professional

According to Akai, the MPK Mini Plus has 37 mini keys, physical pitch and modulation wheels, pads and rotary knobs.

  • Akai lists eight assignable rotary knobs.
  • This model doesn’t have a set of sliders. The extra sequencer and CV features are mainly useful if they suit your set-up.

Native Instruments

The Komplete Kontrol M32 has 32 compact keys and controls for Komplete and NKS plug-ins.

  • Native Instruments describes eight pre-mapped knobs for Komplete and NKS plug-ins, along with touch strips.
  • This integration doesn’t confirm that every third-party string library will be mapped automatically.

Frequently asked questions

Do I need software as well as a MIDI keyboard to get string sounds?

Yes. To play string parts using software, you’ll need a suitable sound source or string library on your computer. Check what software you already have and how it maps MIDI dynamics and expression. Bundled software isn’t necessarily the string library you’re looking for.

How do I set up a control for dynamics or expression?

Start by checking your library’s manual. For its libraries, Spitfire describes CC1 as the default for dynamics and CC11 for expression. It also explains how to use a MIDI Learn feature to assign a control in the BBC Symphony Orchestra plug-in. Don’t assume these settings apply to other libraries without checking.

Can I connect any pedal to a compact controller?

No. It depends on the input and pedal type supported by the specific controller. Arturia lists one input on the MiniLab 37 for sustain, expression or a footswitch. Novation recommends a TS sustain pedal for the sustain input on its controllers, and says that TRS damper pedals won’t work with that input.

What if my MIDI keyboard doesn’t work properly after I buy it?

When you buy as a consumer in the Netherlands, a product must meet the expectations you’re entitled to have of it. According to the Dutch government, there is no fixed statutory warranty period; if a product is faulty, you should contact the seller. Any manufacturer’s warranty is in addition to this.

Does a MIDI keyboard need a CE mark in the Netherlands?

That depends on the product category and the applicable European rules; CE marking isn’t required for every product. The European Union’s Your Europe website says that CE rules apply to certain electrical and electronic equipment. The mark is the manufacturer’s declaration that the relevant product rules have been met. It doesn’t prove that a keyboard will work with your software or suit the way you want to use it. Check the information for the specific model.
