1. WELCOME TO KEYLAB ESSENTIAL
1.1. What’s KeyLab Essential?
Congratulations – you have made a great choice!
KeyLab Essential has been designed to be your best friend when you're making music.
Whether on stage, in studio or while rehearsing and jamming, you need transparency and
direct routes to the sounds you have in your head.
KeyLab Essential is a lighweight and easy-to-use MIDI keyboard controller. But don’t let
its elegant appearance fool you — it’s huge on features usually found in more expensive
keyboards.
Not only can you use KeyLab Essential to play your sound modules (inside or outside of
your computer), but also control important functions inside your DAW. This will boost your
workflow!
KeyLab Essential automatically recognizes and controls popular DAWs including Ableton
Live, Apple Logic Pro, Bitwig Studio, Image-Line FL Studio, and Steinberg Cubase. On top of
that, KeyLab Essential can control any DAW using the MCU/HUI protocol.
You can control your DAW transport with dedicated Transport buttons, use the knobs to
tweak plug-in parameters, and adjust track volumes and pans by using the KeyLab Essential
faders.
A complete keyboard production studio, KeyLab Essential also comes with the incredible
Arturia Analog Lab V – your very own vintage and modern keyboard collection, with access
to over 2000 presets from the award-winning V Collection, ready to customize and play in
an instant.
Whether you want a searing-hot synth lead or an ethereal string pad, a vintage upright
piano or a complex, animated soundscape, KeyLab Essential gives you everything you need
to perform and record. All the ingredients of the cocktail are there and ready to be mixed
according to your own style.
2 Arturia - User Manual KeyLab Essential mk3 - Welcome to KeyLab Essential

Nine endless encoder knobs and nine faders give you hands-on access to numerous sound
sculpting parameters inside Analog Lab V. Other V Collection instruments can also be
remotely controlled whis way, when you customize the settings in MIDI Control Center. Live
sound editing should always be this easy!
You’ll play KeyLab Essential's 49 or 61 velocity sensitive, synth-action keys. The eight backlit
performance pads sense velocity and aftertouch. Plus there are Pitch Bend and Modulation
Wheels, of course.
Please note, that the front and rear panels of the 49- and 61-key keyboards sport exactly the
same buttons, knobs, faders and connectivity. They're just spaced a bit differently on the
larger models.
On top of that, Arturia's MIDI Control Center software (a free download) lets you map
parameters directly to KeyLab Essential’s physical controls to create custom configurations.
You can then save these as user programs and recall them from the KeyLab Essential
hardware.
! For further information MIDI Control Center, please consult MIDI Control Center manual, an app
available for download from the Arturia website.

2. INSTALLATION
The first thing to do upon receiving your KeyLab Essential keyboard, after having completed
the registration process, is to update its firmware. Indeed, Arturia releases periodic
firmware updates to add functionality and improve performance.
To proceed with the update, you'll first need to download and install the MIDI Control Center,
the powerful companion software we designed to work with our hardware, from the KeyLab
Essential's Resources page.
Once this is done, you can follow these steps to upgrade the firmware of KeyLab Essential:
1. Download the latest firmware from the KeyLab Essential's Resources page.
2. Launch MIDI Control Center.
3. Please make sure KeyLab Essential 3 is selected under Device in MIDI Control Center.
Click on the box showing the firmware revision:
4. Click “Upgrade” in the dialogue box that follows, then navigate to the firmware file on
your computer and select it. The four buttons are now lit in blue, running in cycle.
5. Follow the rest of the onscreen instructions. When the firmware loading is complete,
KeyLab Essential will restart and be ready for use.
Once your KeyLab Essential is ready, you can start using it to control various virtual
instruments, like our own Analog Lab V [p.34].
For more information on how the MIDI Control Center works with the KeyLab Essential,
please refer to the dedicated manual in the KeyLab Essential section of our Downloads &
Manuals page.

3. HARDWARE OVERVIEW
3.1. Connecting KeyLab Essential
First of all, we recommend that you install the Analog Lab V and MIDI Control Center and
be sure to register and authorize them. Connect KeyLab Essential to your computer using
the included USB cable. Power and data is supplied through this connection.
You are strongly recommended to download the MCC and let it install KeyLab Essential's
custom driver. Without this specific driver under Windows, you won't be able to use MIDI
with multiple instances that use MIDI protocol on your computer.
3.2. Front Panel
The controls on the front panel of KeyLab Essential are as follows.
Number Name Description
1. Wheels [p.9] These easy-to-reach controllers act as pitch-bend and modulation wheels.
2. MIDI Ch button This button lets you select MIDI out channel.
3. Bank button Choose to use Bank A or B for the Performance Pads.
4. Transp –/+ buttons Transpose the keyboard in semitone steps.
5. Octave –/+ buttons Transpose the keyboard up or down an octave.

!Velocity sensitive: Both the MIDI keyboard and the pads on KeyLab Essential are sensitive to how
hard you play them. Hit harder for higher volume.
!Pressure Sensitivity: Playing a pad and then pressing it harder will send out Pressure data that can
trigger various modulation changes (filter, volume etc.).
Pressure sensivity is often called Aftertouch. KeyLab Essential pads use the more luxurious version
called Polyphonic Aftertouch, where each pad sends out individual data.
Arturia - User Manual KeyLab Essential mk3 - Hardware Overview 7

3.3. Rear Panel

KeyLab Essential, when the MIDI connector is used.
3.4. Display
By default, the main Display momentarily shows a graphic of whatever control you touch,
along with the value sent by that control as you move it. For example, this is what is
displayed when you move a knob:
When you strike a pad, the display first shows your initial velocity. If you then apply after-
pressure, it will display that value.
8 Arturia - User Manual KeyLab Essential mk3 - Hardware Overview

4. KEYLAB ESSENTIAL OPERATIONS
4.1. Wheels
To the left is the pitch-bend wheel. It is spring-loaded: If you push it in one direction and
then remove your finger, the wheel snaps back to its center position. The bend range can
be adjusted in the MIDI Control Center software (see separate manual). In fact, the MIDI
Control Center app allows you to customize the function of almost every physical control of
your KeyLab Essential or other Arturia controller.
Pushing the modulation wheel on the right increases the modulation amount. As with a
modulation wheel on any synth, the wheel and its current value stays where you leave it
when you remove your finger, until you manually move the modulation wheel again.
The modulation wheel by default sends MIDI CC 1 (the usual control number for
modulation), but this control number can also be changed in the MIDI Control Center app.
If you want to control the Volume or Filter Cutoff Frequency or any other parameter of your
sound device, this can be done.
Movements of these wheels will be reflected in the Display.
4.2. MIDI Channel
When working in a DAW or multiple hard- or software instruments, you may want to decide
what MIDI channel KeyLab Essential uses to send notes and controller data. You can easily
change that channel number by holding the MIDI Channel button and pressing the correct
key on the keyboard.
The notes from the lowest C to D# (Eb) in the second octave set MIDI channels to 1–16.
Example: If you want to transmit on channel 10, hold the MIDI Channel button and hit the
lowest A key.
Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations 9

The MIDI channel numbers are printed on the front panel for easy reference.
4.3. Bank
KeyLab Essential has 8 Pads that allow you to conveniently play MIDI notes or drum sounds.
While only 8 pads may seem a bit meager, you can actually use 2 banks. This enables you
to play/trigger a total of 16 (8 + 8) notes.
By default, Bank 1 plays MIDI notes 36 (C1) to 43 (G1). Bank 2 plays 44 (G#1) to 51 (D#2).
Pad Bank 1 2 3 4 5 6 7 8
A 40 (E1) 41 (F1) 42 (F#1) 43 (G1) 36 (C1) 37 (C#1) 38 (D1) 39 (D#1)
B 48 (C2) 48 (C#2) 50 (D2) 51 (D#2) 44 (G#1) 45 (A1) 46 (A#1) 47 (B1)
You can switch between Bank 1 and 2 by pressing the Bank button. While doing so, the
Display confirms what Bank is currently selected.
! When Bank B is selected, the Bank button shines brighter.
10 Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations

4.4. Transpose –/+ and Octave –/+
To transpose the keyboard up or down one semitone, press Transp– or Transp+. When the
keyboard is transposed one or several semitones, the button shines brighter.
! By pressing Transp– and Transp+ at the same time, any transposition shift is reset.
To shift the keyboard up or down an octave, press the Oct– or Oct+ button. You can transpose
3 octaves down and 3 octaves up. When the keyboard is transposed one or several octaves,
the button shines brighter.
! By pressing Oct– and Oct+ at the same time, any octave shift is reset.
The Display will reflect your action in either case. Transpose and Octave-shift apply to the
keyboard only, not the pads. The pads send MIDI note numbers, and those note numbers
may be edited in the MIDI Control Center app.
Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations 11

4.5. Pads
The eight velocity- and poly pressure-sensitive pads on KeyLab Essential serve multiple
purposes. In their default state, they send MIDI notes on channel 10 – the channel most
commonly used for drums in a DAW or multi-timbral synthesizer.
Press Bank to switch between pad banks A and B. Bank B sends other MIDI notes, also on
channel 10. The default note numbers — which may all be changed for User Modes in the
MIDI Control Center app — are:
Pad Bank 1 2 3 4 5 6 7 8
A 40 (E1) 41 (F1) 42 (F#1) 43 (G1) 36 (C1) 37 (C#1) 38 (D1) 39 (D#1)
B 48 (C2) 48 (C#2) 50 (D2) 51 (D#2) 44 (G#1) 45 (A1) 46 (A#1) 47 (B1)
! Every time you press the Bank button, the Display will confirm what Bank is currently selected.
12 Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations

4.6. DAW Control Section
KeyLab Essential allows you to remotely control your DAW. We have created DEEP scripts
for 5 major DAWs:
• Ableton Live
• Apple Logic Pro
• Bitwig Studio
• Image-Line FL Studio
• Steinberg Cubase
KeyLab Essential automatically recognizes the above DAWs. On top of that, KeyLab Essential
can control any DAW on the market thanks to the MCU and HUI protocols.
! In order to use this sophisticated version of DAW Control, the scripts must be properly installed. To
do so, please upload the latest version of your favorite DAW.
! You can download dedicated User Guides for each DAW from the KeyLab Essential's Resources
page.
You enter DAW mode by pressing the Prog button until the display says DAWs. This mode is
required if you want a deep integration using the scripts written for the 5 above mentioned
DAWs. DAW Control works in any of the Prog modes thanks to the MCU and HUI protocol.
The twelve buttons to the left of the Display are all DAW related, although Save, Undo and
Redo can also be used in Arturia Software. These buttons send control messages to your
software, and they are designed to work conveniently with any DAW. If you want, you can
re-configure these buttons in MIDI Control Center.
Using the industry standard Mackie HUI data language, KeyLab Essential gives you direct
access to the most frequently used commands in your recording software, including:
Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations 13

•Save: Saves your track.
•Quant: Turns Quantize on and off.
•Undo: Reverses your last action, such as deleting a track, or capturing a MIDI
performance.
•Redo: Reverses your last Undo action.
The DAW Command Center also puts popular transport controls at your fingertips:
•Loop: Toggles the Loop function in your DAW on and off. The loop region is set
within your software.
•Rewind/Fast-forward: Quickly jogs the playback cursor back and forth, letting
you conveniently find specific points in your track while editing.
•Metronome: Toggles your DAW’s metronome on and off.
•Stop: Stops playback. In some recording software, this will also return the
playback cursor to the start of the track.
•Play/Pause: Starts and pauses your track at the current position of the playback
cursor in your DAW.
•Record: Arms the record function in your DAW. Hitting the Record button while
the track is stopped will begin playback while recording. If the track is already
playing, hitting Record will begin recording from the current playback cursor
position.
•Tap: Tap Tempo to enter a BPM value.
The buttons in the DAW Command Center default to a general workable configuration, and
you can re-configure them in MIDI Control Center.
The output of the DAW Command Center can be toggled between MCU and HUI protocols
within the MCC.
NOTE: KeyLab Essential's compatibility with your chosen DAW will depend on how each
manufacturer handles the MCU and HUI protocols. For more information, consult the KeyLab Essential
page on the Arturia website, or the documentation of your preferred DAW.
•User Programs: KeyLab Essential can store up to 6 User Programs — custom
control mappings you have created in the MIDI Control Center app (see separate
manual). User Presets may be individually enabled or disabled in the Device
Settings of the MIDI Control Center app. We will explain what to do in more detail
in Chapter 5, but for now, know that holding Prog and pressing a Pad will select
any enabled user presets alongside the ARTURIA and DAWs modes as described
above.
4.6.1. MIDI Setup in you DAW
When using KeyLab Essential with a DAW, it is important that you get the MIDI setings right.
In your DAW, probably under Preferences and Audio or MIDI setup, there should be a page
that describe the MIDI inputs and outputs. After selecting KL Essentrial 49/61 mk3 and your
MIDI controller, you'll fund further options.
14 Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations

•KL Essential (49/61) mk3 MIDI: Enables MIDI communication via the USB-C port
on KeyLab Essential.
•KL Essential (49/61) mk3 DINTHRU: Passes outgoing MIDI information from the
host software through KeyLab Essential’s 5-pin MIDI out connector. This can be
useful when you want to sequence and control hardware synths with your DAW
using KeyLab Essential as a MIDI interface.
•KL Essential (49/61) mk3 MCU/HUI: Enables KeyLab Essential as a Mackie
Control Universal surface via a dedicated port, to not interfere with other MIDI
messages as notes or control changes.
•KL Essential (49/61) mk3 ALV Transmits screen messages from Analog Lab V to
KeyLab Essential.
You will almost always want KL Essential (49/61) mk3 MIDI turned on. If using KeyLab
Essential to control any of the custom supported DAWs [p.43], ensure KL Essential (49/61)
mk3 MCU/HUI is not activated.
This is the MIDI device settings page in Studio One
Arturia - User Manual KeyLab Essential mk3 - KeyLab Essential operations 15

4.7. Prog
