Start by choosing a MIDI controller that fits your available desk space, the range you need to play and the controls your string library uses. A compact keyboard leaves more room to work; a larger model can make it easier to play longer phrases and offer more hands-on control. Check the pedal input and software compatibility for the specific model you’re considering.
Who is this for?
String arranger with limited desk space
You use your desk for both computer work and playing, and want enough room left to get on with your work. Compare the stated dimensions with the playing range you need; the number of keys alone won’t tell you whether a controller will fit on your desk.
Arranger who wants hands-on control of expression
You want to adjust dynamics or expression as you play, and switch between articulations. The right control depends on the assignments in your string library.
Player of longer string phrases
You want to play phrases with fewer octave changes, so you’re weighing up having more keys against the width of the keyboard on your desk.

Who is this important for? |
| Dynamics, expression and articulations |
Check your library’s MIDI assignments, which controls you can use and whether the pedal input actually supports expression. |
If I want to control dynamics and articulations as I play, I look for controls supported by my library. Around 31% of consumers put expression and articulations first. |
| Playing range and key size |
Play a representative phrase and check where your library’s keyswitches are. Compare the number and size of the keys for the exact model version. |
For longer lines, I want to switch octaves less often and keep the keys within reach. Around 25% of consumers put playing range first. |
| Desk space |
Measure the available width and depth in your playing setup, and leave room for connections and cables too. |
If I also need space for computer equipment at my workstation, I check the dimensions before choosing a keyboard. Around 25% of consumers start with the desk space available. |
| Compatibility with your DAW and string software |
Check support for your DAW and plugin. Look for MIDI Learn or a suitable script or preset. |
If I want to control my DAW and plugin directly using the controls, I first check that they’re compatible with my software. Around 19% of consumers prioritise software compatibility. |
Common buying pitfalls with MIDI controllers
-
Assuming a sustain input supports continuous expression
According to Novation, the pedal input on the Novation Launchkey 49 is designed for sustain pedals and momentary footswitches. That doesn’t mean you can connect an expression pedal to it.
Check the type of pedal input on the exact model before choosing an expression pedal.
-
Counting the keys but overlooking where the keyswitches are
Articulation keys may fall outside the area you can reach directly on your keyboard, so you may need to change octaves or adjust the assignments.
Check your library’s keyswitch notes and consider whether changing octaves or using a custom assignment will work for you.
-
Assuming an older model generation is the same product
Akai documents functional differences between the MPK Mini MK3 and the MPK Mini IV. Check the full model name and generation before choosing a version.
Compare the model name with the manufacturer’s specifications to make sure you’re checking the features of the right generation.

Frequently asked questions
How do I switch string articulations while arranging?
Start by checking how your string library handles this. Spitfire documents keyswitches for its libraries. In BBC Symphony Orchestra Discover, the default keyswitches are on C-2 to D#-2, according to Spitfire, and can be moved if your keyboard can’t reach those keys.
How do I assign a fader to dynamics or expression?
If your plugin supports MIDI Learn, select the parameter you want to control, then move the control you want to assign. Spitfire describes CC1 as the standard for dynamics in its libraries; check the settings for the library you use.
Can I connect an expression pedal to the sustain input on a Launchkey 49?
Don’t assume you can: Novation describes the input as suitable for sustain pedals and momentary footswitches. For continuous expression, use an input that’s designed for it and supported by the exact model, or assign a different control.
Do I have a cooling-off period when buying online in the Netherlands?
According to the Dutch government, when you buy from a business at a distance, you generally have a 14-day cooling-off period. Not every transaction or type of product is covered, so check the terms for your specific purchase.
Is there always a fixed statutory two-year guarantee in the Netherlands?
No. According to the Dutch government, the Netherlands has no fixed statutory guarantee period: you’re entitled to a product that works properly, and factors such as its expected lifespan play a part. If there’s a problem, contact the seller.
