A number of years ago, I played keyboards in an electronic band and was given the job of working out how we could reproduce our recorded parts live.
At the time, I was using a Korg X50 synthesiser. It could do a lot on its own but things became more difficult once we started adding software instruments, samples and backing tracks from a laptop.
The recorded songs had become bigger than the setup I was using on stage. I could play the main keyboard parts but still had samples to trigger, sounds to change and other sections running from the computer.
I soon found myself thinking more about the laptop than the song.
Not ideal.
A keyboard controller can help with this. You get the normal keys but can also have pads, faders and knobs ready for different parts of the show.
The controller itself will not usually provide the sounds. It sends the notes and control changes to software or another instrument.
Pressing a key can play a software piano. A pad could start a sample. A fader might bring a backing track up or down.
For this comparison, I have picked three models available through Amazon.com:
- Novation Launchkey 49 MK4
- Arturia KeyLab Essential 61 mk3
- M-Audio Oxygen Pro 49
They take slightly different approaches.
The Novation has the most pads. The Arturia is the only one with 61 keys. The M-Audio is there for someone who wants to map more of the controls themselves.
What Should You Look for in a Live Keyboard Controller?
I would begin with the number of keys.
A 25-key controller can work for triggering samples or playing short synth parts. Once both hands are involved, the space disappears quickly. The Novation and M-Audio have 49 keys. For many synth, organ and chord parts, that will be enough. They are also smaller than the Arturia which can make a difference once the keyboard has to fit into a car or onto a crowded stage.
The Arturia has 61 keys. Those extra notes help when the part moves across more of the keyboard. They also leave more room if you are splitting the keys between two sounds.
The octave buttons on a 49-key controller can move the range up and down. I have always found this fine until the octave needs to be changed halfway through something I am playing.
The pads, faders and knobs are another part of the decision. Pads can trigger samples, drums, clips or chords. Faders can change the volume of different tracks while knobs may be used for effects and software settings.
The Launchkey has 16 pads, eight encoders and nine faders. The Arturia has eight pads, nine encoders and nine faders. The Oxygen Pro also has pads, knobs, buttons and faders which can be assigned inside the software.
The keyboards will not all feel the same either. The Novation has semi-weighted keys. There is a little more resistance than you normally get from a light synth keyboard but it will not feel like a weighted digital piano. The Arturia uses a lighter keyboard action. Neither is automatically better. It depends on whether you prefer a lighter synth feel or a little more resistance.
I would also check the software before buying anything.
A controller may connect and map itself inside one DAW but need more work in another. Make sure the functions you intend to use live are actually supported by your software.
Novation vs Arturia vs M-Audio: What Is the Difference?
The Novation Launchkey 49 MK4 has 49 semi-weighted keys, 16 pads, eight encoders and nine faders. Chord, scale and arpeggiator tools are also built into it. This is the one I would first look at for Ableton, samples and clips.
The Arturia KeyLab Essential 61 mk3 is wider and gives you 61 keys. It also has eight pads, nine faders and nine encoders.
Arturia’s Analog Lab software is a big part of the package. Sounds can be browsed and adjusted from the keyboard instead of moving back to the laptop each time.
The M-Audio Oxygen Pro 49 has 49 keys and a large collection of controls.
DAW mode can operate the mixer and transport. Preset mode is for instruments and mappings you have saved yourself.
For me, the comparison comes down to this:
- Novation for Ableton, pads and clips
- Arturia for the 61-key range and Analog Lab
- M-Audio for custom control
Do You Need 49 or 61 Keys for Live Performance?
I used to think more keys automatically meant a better keyboard. The problem is that someone has to carry it. A 61-key controller is wider. It needs a wider stand and takes up more room in the car. That may be completely fine when the parts need it.
A piano section that moves across the keyboard is easier with 61 keys. The same goes for a split where the left hand plays one sound and the right hand plays another. For synth lines, organ parts and normal chord sections, 49 keys may be plenty.
Both the Novation and M-Audio have octave controls for reaching notes outside the keyboard’s normal range. That works well until you need to change octaves in the middle of a part.
I would look at the songs in the set before choosing.
Can everything be played inside four octaves?
If yes, the smaller keyboard will probably be easier to live with.
If you keep running out of notes or rely heavily on keyboard splits, the Arturia has the advantage.
Can You Use a MIDI Keyboard Controller Without a Laptop?
A keyboard controller needs something else to make the sound. For many live setups, this will be a laptop running Ableton Live, MainStage or another DAW. You could also connect the controller to a hardware synthesiser, sound module or compatible tablet.
The keyboard sends information about the notes and controls you use. The connected device provides the actual sound. This is why plugging a controller directly into a speaker will not work.
A basic live setup may include:
- The keyboard controller
- A laptop, tablet or sound module
- Performance software
- USB or MIDI cables
- An audio interface
- A connection to the venue’s sound system
- A keyboard stand
- A sustain pedal
- Spare cables
I would also have a backup plan. Computers freeze and USB cables fail. I would turn off automatic updates before leaving home and run through the whole set using the exact laptop, interface and cables planned for the show.
I would also save the project and sounds locally. The internet is the last thing I would want to depend on while standing on stage.
Novation Launchkey 49 MK4
The Akai MPK Mini MK3 is a great little grab-and-go controller. With 25 mini keys, it fits easily in a backpack but still gives you pads, knobs and a built-in joystick for pitch and modulation.
- 25 mini keys
- 8 pads
- 8 knobs
- Very light
Why Is It Great?
I think this is the best pick for performers who care most about portability. It is small, light and easy to carry, but it still gives you enough control to trigger samples, play basic parts and tweak sounds live. It is not trying to be a full stage keyboard. It is more for players who want something compact that still feels useful.
The Pros & Cons of Novation Launchkey 49 MK4

FAQ
Does a keyboard controller make its own sounds?
Most controllers do not.
A laptop, tablet, sound module or hardware synthesiser normally provides the sound.
There are keyboards with built-in sounds but the three products in this comparison are controllers.
Is 49 keys enough for live performance?
Forty-nine keys should cover many synth, organ and chord parts.
It may feel cramped for wider piano arrangements or keyboard splits. In that case, the 61-key Arturia gives you more room.
Can I use a keyboard controller with Ableton Live?
Yes.
All three can work with Ableton Live.
The Launchkey is the one I would look at first when Ableton clips, samples and mixer controls are a large part of the show.
What else do I need to use a MIDI controller live?
You will normally need a laptop or hardware sound source, software instruments, an audio interface or other audio output and the correct cables.
A stand, sustain pedal and spare USB cable are also worth packing.
Should I choose the Arturia KeyLab or Novation Launchkey?
The Arturia has 61 keys and controls for Analog Lab.
The Novation is smaller and gives you 16 pads.
I would take the Arturia for piano parts and keyboard splits. I would take the Novation for Ableton clips, samples and a smaller stage setup.
Summary - The Best Keyboard Controllers for Live Performance
I would pick the Novation Launchkey 49 MK4.
The 49 keys keep it at a size I would be comfortable carrying while the pads, faders and encoders give it plenty to do during a software-based performance.
The Arturia KeyLab Essential 61 mk3 would be my choice for wider piano parts or keyboard splits. The M-Audio Oxygen Pro 49 makes sense when the whole setup will be mapped manually.
For the way I would use a controller live, the Launchkey has the best mix of keys and hands-on control.
I would still spend plenty of time testing the laptop, software, interface and cables before using any of them on stage.
Have a great one!
