Who is a MIDI keyboard for synth bass relevant to?

Sound designer working with a DAW

You play in a bassline and want to adjust a filter or another synth parameter using a physical control, for example. Whether this works depends on the MIDI mapping and the support available in your software.

Bassist recording parts

You want to play bass parts on a keyboard with a key size and range that suit you. A larger keyboard also takes up more space in your practice studio.

Player with a hardware synth

You want to control an external sound source. So, assess the keyboard’s connections and power requirements alongside the synth’s input and capabilities.

What should you look for when choosing a MIDI keyboard?

First, decide where the sound will come from and how you want to control it. Then compare the key range with the space available, and, if you’re using hardware, check that the connections and power requirements are compatible.

What to consider What to look for when buying Who should prioritise this?
Controlling sound parameters Check how many controls can be assigned and whether your DAW or synth can control the parameter you want via MIDI. I want to adjust a filter while playing, for example, without interrupting my bassline. Around 36% of consumers say sound control is their main concern when buying.
Key size and range Compare the key size with the bass parts you play, and measure up to check that the keyboard will fit in your workspace. If I want to play bass parts with fewer octave changes, the number of keys matters. Around 29% of consumers prioritise playing range.
Connecting an external synthesiser Compare the output on the exact controller model with the input on your synth, and check the power supply and cables you’ll need. I want to control an external synth during rehearsals, so the connection needs to work with both devices. Around 21% of consumers give hardware connectivity top priority.
Space in your practice studio Measure the available space and check that you can comfortably reach the keys, controls and connected cables. If there’s little room next to my other equipment, I want a keyboard that fits in the space practically. Around 14% of consumers say available space is their main concern.

Common pitfalls when choosing a MIDI keyboard

  • Assuming a MIDI controller is a standalone synthesiser

    A controller sends MIDI messages, but that won’t produce the bass sound you want by itself. Akai specifically states that the MPK Mini MK3 doesn’t make a sound on its own.

    Decide in advance which software instrument or hardware synth will produce the sound.

  • Assuming every knob will immediately control a synth parameter

    A control may require manual MIDI mapping or specific settings in your DAW. How it works depends on the software and synth you’re using.

    Check support for your software version and find out how to set up the MIDI mapping you want.

  • Treating USB, 5-pin MIDI and CV/Gate as interchangeable connections

    Controllers and external synths may use different connections. Even a controller that works via USB needs a suitable power source in a hardware setup.

    Compare the connections and power requirements of both devices before choosing your setup.

Frequently asked questions about MIDI keyboards for synth bass

Will I hear a bass sound as soon as I connect a MIDI keyboard?

Not from MIDI messages alone: you’ll also need a software instrument or connected hardware sound source. Akai specifically states that the MPK Mini MK3 doesn’t make a sound on its own; check this for the model you’re considering.

How do I make a knob control a synth parameter?

First, check that your synth and DAW support the mapping you want. In Ableton Live, you can enable MIDI mapping, select a function and then turn the knob. The exact setup depends on your controller and software.

Can I rehearse with an external synth without a computer?

Yes, if the controller, power supply, connection and sound source are compatible. Novation describes using the Launchkey MK4 with USB power and a MIDI cable connected to external hardware; check the inputs and settings on your synth.
