Who is this choice for?

Composer with a shared workspace

You want to enter string parts, then clear the keyboard from the shared desk. So compare the dimensions and key size of each version. Novation lists the Launchkey Mini 37 MK4 as 478 mm wide, compared with 557 mm for the Launchkey 37 MK4.

Arranger who plays in dynamics

You want to control dynamics or expression with a physical control as you play string phrases. Check how your library maps MIDI functions; Spitfire Audio, for example, describes separate functions for CC1 and CC11.

Player of two-handed parts

You prioritise playing space and key size over the smallest setup. Compare a 49-key version with smaller options, and bear in mind how much room the keybed will take up on your desk.

What should you look for when buying?

First measure the available space, then decide how many keys you need, and finally check that the controls work with your string library and DAW.

What to consider What should you check? Who is this important for?
Desk space Measure the available width and depth, including room for cables. Novation lists the Launchkey Mini 37 MK4 as 478 × 177 mm and the Launchkey 49 MK4 as 730 × 264 mm. If I need to put the keyboard away after use, a compact footprint is my top priority. Around 33% of consumers prioritise saving space.
Dynamics and expression Check which MIDI functions your library uses and whether you can assign them to a wheel, fader, encoder or DAW automation. Spitfire Audio describes Learn MIDI CC as a way to assign a control. If I want to shape dynamics or expression as I play, I want the right control within easy reach. Around 27% of consumers put this type of control first.
Playing space and key size Compare 37 mini keys with 37 full-size keys and a 49-key version. Novation lists all three options for the Launchkey Mini 37 MK4, Launchkey 37 MK4 and Launchkey 49 MK4. If I play parts with both hands, range and key size matter more to me than having the smallest unit. Around 27% of consumers choose mainly on playing space and key size.
Software and controls Check compatibility with your DAW and string plug-in, then test the MIDI assignments you want to use. Native Instruments lists pre-mapped encoders for Komplete and NKS plug-ins on the Komplete Kontrol A49. If I want to keep using my existing software settings, the controls need to work with them. Around 13% of consumers prioritise compatibility with their existing workflow above all else.

Common pitfalls

  • Assuming every control will automatically give you the right string dynamics

    A physical knob or fader needs to match the MIDI function used by your library. Spitfire Audio, for example, distinguishes between CC1 for dynamic layers and CC11 for expression volume.

    Check the CC functions for your own patch and test whether you can assign the control you want to use.

    Allow time for MIDI mapping or setting up DAW automation.

  • Comparing only the number of keys

    The number of keys doesn’t tell you how wide or deep the unit is. The Launchkey Mini 37 MK4, Launchkey 37 MK4 and Launchkey 49 MK4 differ in both dimensions and key size.

    Measure the free space on your desk, including room for cables, and compare it with the dimensions of the exact version you’re considering.

  • Expecting one socket to support two pedal functions

    Arturia lists one input for the KeyLab Essential 49 mk3, which can be used for sustain, expression or a footswitch. This doesn’t mean you can use two separate pedals at the same time through that one input.

    Check the number of inputs and the compatibility of the pedal combination you want to use.

Brands to compare

Novation

The Launchkey MK4 range includes versions with 37 mini keys, 37 full-size keys and 49 keys.

  • Novation says the Launchkey 49 MK4 has nine faders.
  • According to Novation, the Launchkey Mini 37 MK4 and Launchkey 37 MK4 don’t have faders. Check whether the other controls suit your string software.

Arturia

The KeyLab Essential 49 mk3 is a 49-key version with faders, user presets and DAW scripts.

  • Arturia specifies nine faders and a pedal input that can be used for sustain, expression or a footswitch.
  • Don’t assume you can use separate pedals at the same time through that one input; check pedal compatibility too.

Akai Professional

The MPK Mini Plus combines 37 mini keys with wheels and connections for external equipment.

  • Akai lists MIDI/CV/Gate/Clock connections for this model.
  • Akai requires a firmware update before using the MPK Mini Plus; this instruction doesn’t automatically apply to other models.

Native Instruments

The Komplete Kontrol A49 is worth comparing if you work with Komplete or NKS instruments.

  • Native Instruments describes eight pre-mapped encoders for Komplete and NKS plug-ins.
  • Don’t assume the same controls will be available without setup for other string plug-ins.

Frequently asked questions

Do I need a MIDI keyboard with faders for a string library?

No, faders aren’t essential. Spitfire Audio describes both MIDI mapping with Learn MIDI CC and drawing CC1 automation in FL Studio. The right controls depend on your library and DAW.

How do I choose between 37 and 49 keys for string parts?

Choose based on how much playing space you need and how much room you can make available. A 49-key version gives you more keys within reach than a 37-key version, but factor in the dimensions of the exact model when planning your desk space.

Can I connect two pedals to the KeyLab Essential 49 mk3?

Don’t count on getting two separate pedal functions from the same input: Arturia specifies one pedal input that can be used for sustain, expression or a footswitch. Before buying, check the connections and compatibility of the pedals you want to use.

Do I need to set up the Akai MPK Mini Plus first?

Akai requires a firmware update before using the MPK Mini Plus. For other models, check the relevant manual rather than assuming this model-specific instruction applies.

How can I tell whether a wheel or fader controls the right function for my string sound?

Check the MIDI functions in your string library’s manual, then assign the function you want in the library or DAW. Spitfire Audio describes CC1 for dynamic layers and CC11 for expression volume; test the assignment with the patch you’re using.
