1. INTRODUCTION
1. INTRODUCTION
Thank you for choosing the Analog Four MKII. It is a digitally controlled analog synthesizer featuring, among
many things, the renowned Elektron step sequencer. This is truly an analog synthesizer for the creative
artist. To make the most of the machine, we recommend you to carefully read this manual.
1.1 CONVENTIONS IN THIS MANUAL
We have used the following conventions throughout the manual:
Key names are written in upper case, bold style and bracketed letters. For instance, the key labeled “FUNC”
is called [FUNC].
Menu names are written in upper case letters. The OSC1 menu is an example of that.
Parameter names and certain menu options where settings can be made or actions performed are written
in bold, upper case letters. For example, VOL.
Upper case letters are used for parameter setting alternatives, for example, OFF, and certain menu settings,
like LEGATO.
Messages visible on the screen are written in upper case letters with quotation marks. Like this, “BANK A :
CHOOSE PTN.”
Knobs are written in upper case, bold, italic letters. For instance, the knob “Track Level” is called TRACK
LEVEL.
LED indicators like the octave transposition LEDs are written like this: <OCTAVE>.
The following symbols are used throughout the manual:

2. ANALOG FOUR MKII BACKGROUND
2. ANALOG FOUR MKII BACKGROUND
Some things never go out of style. They seem to possess an inner, timeless quality, an objective trait that
sets them apart from the rest. Makes them stand out. They are found in all areas of human activity, throughout history. Including, of course, within the domain of sound.
Making and shaping sound using analog circuits goes far back in time. Initially used in compositions dating
from the first decades of the 20th century, analog circuits were popularized in the 1960s thanks to artists
such as Wendy Carlos. Today, they are frequently emulated by both hardware and software. Their legacy is
impressive. The analog tone and timbre have become synonymous with appealing sounds. Rightly so. The
depth, fullness and slightly skewed characteristics of analog sounds speak directly to us.
We at Elektron owe a lot to analog technology. It is in our blood. The Sidstation, our first product, featured
an analog filter which was decisive in generating the unique sound of the synth. With the Analog Four MKII
we take the next step on our analog journey.
The innovative combination of modern technology and tried and trusted ways of sound generation lets
you experience the analog realm to its fullest. Analog Four MKII is the new benchmark for analog tabletop
synthesizers. Tweaked circuitry delivering deeper bass than ever, new powerful sound control possibilities,
dedicated outputs for each voice. Not to mention the ultra durable buttons, the big OLED screen, and the
premium design. With Overbridge, our award-winning software suite, Analog Four MKII can seamlessly
integrate with DAWs. The Analog Four MKII represents the best of two worlds. Inimitable analog impact
combined with razor-sharp digital accuracy.
The Analog Four MKII is yet another of our contributions to the proud history of analog instruments.

4.1 ABOUT THE COMPONENTS
Both oscillators of each voice are analog. All their elaborate waveshaping abilities are completely analog,
with digitally controlled pitches. The noise generator is digital. The two filters and the overdrive circuit
between them are fully analog. The amplifiers are analog. The envelopes and LFOs are digital. They are
designed for maximum eciency and versatility.
4.1.1 COMMENTS ON THE SIGNAL PATH
The signal path from the oscillators to the audio outputs is completely analog. The signal path from the
external inputs to the audio outputs is also fully analog. The digital send eects are parallel to the main
audio path, and the wet signals from the digital send eects are mixed with the dry analog signal before
the main output stage.
4.1.2 ABOUT THE OSCILLATORS AND FILTERS
The oscillators are designed and built from scratch, to obtain a lush sound and provide an array of
control features. The ladder filter utilizes discrete low-noise transistors, and the multimode filter uses
high-quality VCAs. The combination of tradition and innovation ensures a unique sound with a broad
range of possibilities. For more information, please see “APPENDIX E: ANALOG FOUR MKII ARCHITECTURE” on page 109.

9. KITS AND SOUNDS
9. KITS AND SOUNDS
Kits and Sounds are the basic building blocks of Analog Four MKIIs sound crafting. A kit is a collection of
Sound, FX, and CV track parameter settings. A Sound is essentially a synth track patch, made up by subtractive synthesis from the oscillators through the filters via its various parameter settings. Each of the 4
synth tracks contains one Sound.
Kits and Sounds are separated, meaning kits do not necessarily have to use any saved Sounds. When saving a kit, the PARAMETER page settings of the synth tracks, i.e. the settings that constitute a Sound, will be
saved together with the kit. The synth track PARAMETER page settings of a kit can be saved as individual
Sounds as well. When loading a Sound, it will become a part of the kit. Changes made to the track Sound
does not aect the saved Sound on the +Drive, only the kit. A kit is always assigned to a pattern which
controls the playback of the kit.
A Kit contains:
• Sound settings for the 4 synth tracks.
• FX track parameter settings.
• CV track parameter settings.
• LEVEL settings for the Synth and FX tracks.
• PERFORMANCE mode parameter settings.
• Polyphony settings.
A Sound contains:
• Settings on the PARAMETER pages of a synth track.
The screen graphics in the top left part of the screen shows the name of the currently active
kit. When you press the [TRACK] keys, this information briefly changes to reflect the name of
the track. The name of the track Sound will be displayed for the synth tracks.
Note that several patterns may use the same kit. Changes you make to the kit while editing
one of the patterns will directly aect how the other patterns sound as well. Remember to
save the kit to a new location if you wish to avoid this.
9.1 THE +DRIVE SOUND LIBRARY AND THE SOUND POOL
Sounds can be loaded to a kit from either the +Drive Sound library or the Sound pool of the active project.
The dierence between the two is that the +Drive Sound library has the capacity of 4096 Sounds, available
to all projects, while a Sound pool is a part of a project and limited to 128 Sounds. The primary benefit of
Sounds loaded to the Sound pool is the possibility for them to be Sound locked. This feature is not available
for the Sounds in the +Drive Sound library. For more information, please see “10.12.2 SOUND LOCKS” on
page 48.
9.2 KIT MENU
In the KIT menu, commands relating to kits are found, most importantly kit save and load. Open the menu

Up to five track parameters can be assigned to a performance macro. Parameters can be selected from
all six tracks. Press DATA ENTRY knobs A–E to select track. Turn DATA ENTRY knobs A-E to select the
parameters that you want to assign. Press the knob or press [YES] to confirm a selection. DATA ENTRY
knobs F-J are then used to set the depth of the five track parameters. The depth is an oset of the original track parameter value.
By default, the parameter macro knob spans a parameter value range of 0-127. A parameter macro value
of 0 will not introduce any changes to the sound. Press the TRACK LEVEL knob to make the performance macro knob work in a bipolar fashion, meaning the parameter macro value range will go from -64
to +63.
While a pattern or Sound is playing, turn the TRACK LEVEL knob to preview how the performance macro
aects the sound.
Press [FUNC] + [QPER] to mute the PERFORMANCE mode. This temporarily mutes all the
changes that have been made to the track parameters by the performance macros. Press
[FUNC] + [QPER] again to unmute the PERFORMANCE mode to let the changes aect
the parameters again. The [QPER] key is green when PERFORMANCE mode is active and
turned o then PERFORMANCE mode is muted.
Use performance macros to aect the most relevant parameters when playing live. By
carefully setting up parameter macros you might find that you don’t have to leave this
mode at all during your live set.
It is not possible to parameter lock PERFORMANCE mode parameters.
9.3.3 PERFORMANCE RENAME
Allows performance macro knobs to be named. Use the [UP] and [DOWN] arrow keys to select the
DATA ENTRY knob corresponding to the performance macro that will be named. Press [YES] to confirm
the selection. The NAMING menu will appear.
9.3.4 PERFORMANCE TRACK MUTE
Track muting can also be done while in PERFORMANCE mode. (You can also use standard Track Muting.

mode, [TRIG] keys 1–6 mute the tracks. An outlined square in the track mute section and a full bright
[TRIG] key means a track is audible. A minus sign and a dimmed red [TRIG] key indicates the track is
muted. While holding [FUNC] and pressing one or more of the six first [TRIG] keys, the mute changes
will be held until [FUNC] is released. A track that is currently muted, but will be unmuted when [FUNC]
is released, is indicated by a “+” sign and a half-bright [TRIG] key. A track that is currently not muted, but
will be muted when [FUNC] is released, is indicated by an asterisk and a half-bright, blinking [TRIG] key.

QUICK PERF AMOUNT knob without being in PERFORMANCE mode.
1. Press and hold [QPER], and then press one or more [TRIG 1–10] keys to select which performance
macros you want to control with the QUICK PERF AMOUNT knob. The [TRIG 1–10] keys correlate to
the 10 performance macros you have at your disposal.
2. Release [QPER].
Every time you perform this procedure you remove any earlier assignments.
For more information, please see “9.3.2 PERFORMANCE CONFIGURE” on page 26.
9.5 POLYPHONY
Four voice polyphony can be configured by selecting POLY CONFIG in the KIT menu. The Analog Four
MKII is capable of four voice multitimbral polyphony (or unison). This is possible due to the powerful sound
engine which is able to change sound instantly and allow completely dynamic voice allocation (see figure
below). The sequencer is fully polyphonic, allowing overlapping notes and chords to be programmed on the
tracks. Any track can play up to four notes using its track sound. Notes are distributed to the synth voices
according to the selected allocation method. Any of the synth voices can also be poly-disabled, allowing
tracks to have their dedicated, monophonic synth voice available at all times. The poly configuration is
stored per kit, for maximum flexibility, allowing up to 128 dierent poly configurations per project.

9. KITS AND SOUNDS
VOICES Select any combination of the four voices to be poly activated by using the [LEFT] and [RIGHT]
arrow keys. Tick or untick a box by pressing the [YES] key. To activate/deactivate voice 1–4 directly,
press the [TRIG 1–4] keys. When in the POLY CONFIG menu, the [TRIG 1–4] keys on the front panel will
be half-bright. When a voice is activated, the corresponding [TRIG] key will be full-bright. Voices that are
not set to be poly enabled will be dedicated monophonic voices for their corresponding tracks. These will
never be used for polyphonic playback. Voices that are poly enabled can be allocated dynamically by any
of the poly enabled tracks.
ALLOCATION changes the allocation method of the poly voices or sets all poly enabled voices to play
simultaneously (RESET, ROTATE, REASSIGN or UNISON, respectively). Select method with the [LEFT]
and [RIGHT] arrow keys. For a visual explanation of the dierent allocation methods, see VOICE ROUTING below.
The [TRIG 1–4] keys will flash to show voice activity depending on the selected method. Select the method, play a few notes on the keyboard and watch the LEDs to get an immediate,
visual impression of how the dierent allocation methods work.
RESET Picks the first available voice in increasing order, starting from track voice 1, for every new
overlapping note played.
ROTATE For every new coinciding note played the voices are allocated cyclically.
REASSIGN Uses the same voice as last time for every note played as long as it is unused. Otherwise,
the least recently used voice is used for the new note.
UNISON Uses all voices to play the same note. Employs the adjustable parameters DETUNE and PAN
SPREAD mentioned below.
USE TRK SOUNDS forces the selected voices to use the Sounds of the four tracks, instead of letting the
voices dynamically use the played Sound. Tick/untick box to activate/deactivate using the [YES] key or
the [LEFT] and [RIGHT] arrow keys.
UNISON DETUNE sets the oset (0–127) by which the selected unison voices will be detuned. Decrease
or increase the oset with the [LEFT] and [RIGHT] arrow keys.
UNISON PAN SPREAD set the width of the pan spread (0–127) around the center point of the unison
sound. Use the [LEFT] and [RIGHT] arrow keys to set the value.
If no free voice is found, the least recently used voice is stolen and used for the played note. See illustration below. This applies to all allocation methods described above.
9.5.2 VOICE ROUTING
Set custom voice routing by accessing VOICE ROUTING, found in the KIT menu.
Activate/deactivate routing of any the four voices to the main output and to the FX track. Navigate using
the [ARROW] keys. Tick or untick box with the [YES] key.
Alternatively, instantly activate or deactivate voice to main or voice to FX using the [TRIG] keys 1-4 and
9-12, respectively. Red LEDs above these sets of keys will indicate if the voice is active (full-bright) or
inactive (half-bright).
Note that voice routing can be set and stored for each KIT. If you want to use the GLOBAL voice routing
setting, tick the box USE GLOBAL SETTINGS using the [YES] key.
