Welcome to the Erae world! Here's a quick guide to the key terms you'll encounter:

• The Lab: Erae's companion software, designed to configure your device in countless ways. In the Lab, you can manage your projects and layouts
• Element: The basic building blocks for creating layouts. Examples include keyboards, drum pads, and faders. A full list of elements can be found in the Elements section.
• Layout: An arrangement of elements on the playing surface. Layouts can be customized with "tune" and "style" settings in the Lab. You can also adjust "tune" settings directly on the device. Both "tune" and "style" parameters are layout-specific, meaning they are saved and edited within their individual layouts.
• Loop: A repeating sequence of MIDI and/or CV events, such as notes, chords, or rhythms. Loops can be recorded in real time, then saved and edited as "patterns."
• Project: A file that can contain up to 8 layouts. Erae's SD card can store up to 8 projects, allowing you to manage and organize your work efficiently.

Playing Surface

The Erae features a built-in array of 16,000 force sensors and 1,000 RGB LEDs, paired with the powerful Erae Lab configuration software. This combination enables limitless customization, supporting up to 8 layouts per project and 8 projects stored on the included SD card. With Erae Lab, you can design your pad to suit your needs by incorporating elements like sliders, 2D sliders, keygrids (isomorphic layouts), or keyboards. The device also includes 8 factory layouts, showcasing its versatile possibilities. Note that many layouts are routed across various channels, with some designed specifically for MIDI Polyphonic Expression (MPE).

Bouton Panel

Individuel boutons enable directs access to:

• Layouts (1 to 8)
• Looper section
• Octave up & down
• Scale, Mapping, Loop and Arpeggiator
• Settings and Undo

Screen and Click-wheel
Easily navigate and adjust parameters directly on the device using the click-wheel and screen interface. Most parameters on the screen's UI can be navigated by rotating the wheel and selected with a click.

I/O

From left to right (top view point of view), Erae 2 features:

• 12 dual jack outputs, with outputs 11 and 12 also functioning as footswitch pedal inputs.
• One SD card reader supporting up to 8 projects.
• One MIDI input and two MIDI outputs.
• One USB Host port to control USB-compatible synths or receive MIDI from other controllers.
• One USB Device port to send MIDI to a computer.
• One USB port dedicated to the power supply.

Layouts

Each button, numbered from 1 to 8, corresponds to a specific layout. When you press a button, Erae displays the associated layout, allowing you to play it!

Octave selection

Buttons allow you to change the current octave of the pitched element (keygrid, keyboard, drumpad, note) you touched last.

Scale

To adjust the scale of pitched elements, follow these steps:

The Scale menu consists of three columns:

• Scale Mode (e.g., Major, Melodic Minor, Harmonic Minor, etc.)
• Root Note
• Octave (range: [-2; 8])

‍

‍

Mapping

Touch the mapping mode button to change the output routing, MIDI channel, Control Change (CC’s), de/active MPE, expressive parameters (pitch bend, pressure, etc.) and more. 

Remember the menu affects the last touched element.

‍

To edit Mapping elements, navigate through the menu and hover the element you wish to modify. Click and rotate the wheel to make changes. Certain parameters have simple on/off states that can be toggled, while others allow fine-tuning within a [0–100] scale.

NB : These mode parameters can be edited from the Lab or from the Erae. 

‍

Arpeggiator

The Arpeggiator is triggered on all pitched elements (Keygrids, Keyboards, Drumpads, Buttons and Notes) once you click the arpeggiator button. First select one pitched element by touching it before hitting the arpeggiator button. The arpeggiator has four parameters:

• Rate - Default: ¼, Range [1/32; 1/1], last value is Pressure, meaning the ARP rate gets faster as you press harder
• Style -  Default: Up,  Values: Up, Down, Up & Down, Random
• Octave - The range across which spans the Arpeggiator - Default value is  1, Range: [0;8]
• Pressure - Finger pressure controls the arpeggiated notes velocities 

The looper serves as the default screen for all layouts. It displays time with a red circle expanding over a grey background. In this initial version, the looper allows you to adjust three parameters:

• The number of steps: Default value: 16 steps, range: [0;64]
• The time division: Default value: ¼, range [Off; 1]
  Nb: Time division acts like quantisation, set to Off, is similar to no quantisation. 
• The - Beat Per Minute -  BPM can be set here for all layouts/loops. 

‍

‍Looping gestures

The Erae looper records gestures (x,y,z touch data) and not MIDI nor CV data.
This means you can keep looping while transposing octaves, changing scales and changing mapping.

Elements

The playing surface is where interactive elements come to life, enabling you to engage with and customize your performance. These elements may include:

• Keyboards/keygrids/drumpads: Assign and play notes, beats, or patterns.
• Notes: Trigger sounds or effects with pressure-sensitive touch.
• Sliders: Adjust parameters dynamically by sliding your fingers.
• 2D Sliders: Manipulate up to three parameters simultaneously by moving across the surface.
• Buttons: Switch between modes, toggle effects, or activate features.

‍
Each element is crafted for intuitive interaction, enriching your creative experience. As the fundamental components of all layouts, elements can be arranged and customized within a layout using the Erae Lab. A layout can consist of one or multiple elements, which can be positioned, duplicated, edited, or removed as needed in the Erae Lab.

Keygrid

Keygrids consist of rectangular cells arranged in a grid. Horizontally, the cells are spaced by intervals such as a semitone, a tone, or larger steps, while vertically, they are separated by intervals like a fourth (or greater, adjustable using the line offset attribute, similar to string instruments). The chosen scale determines the precise interval relationships between the rows and columns.

By default, every note on the Keygrid is in the key of C major. Two joint keys on one same line will be separated by one degree of the same scale. In this C Maj example, the root note is C. Moving to the right, each key is the next note in the C major scale. Moving upward, each key is a fourth higher. Again, the note interval between lines can be adjusted in the Lab with the Line Offset.

‍

Scales 

Changing scales adjusts the arrangement of note intervals, but the root note, third, and fifth remain highlighted. These highlights and their styles can be customized in the Lab.

Chromatic keygrid

To play chromatically on the keygrid, enable the "Show Offscale" option in the Lab's scale settings menu. Disabling this option will fold the keygrid, showing only the notes within the selected key. By default, notes outside the key are displayed in grey, but you can personalize their appearance in the Lab.

Keyboard 

Keys are replicas of traditional keyboards. There are many original ways to represent black and white keys, play around with the Style section in the Lab and find out what works best for you. 

Scales

You can highlight in-scale notes to visualize various scales (such as Major, Minor, or Blues), simplifying the process of learning and playing.

Buttons

Buttons trigger notes with selected pitch on a selected channel. They can be used for launching clips on Ableton Live or triggering a button on a hardware synth. They can also be used as switches, with distinct on/off states, by setting the Latched option to on in the Lab. 

1D Fader

Sliders provide continuous variation along one dimension, between two defined values, using a specific MIDI channel and Control Change. They can be mapped to both control changes and control voltages (CV), even simultaneously if required. Their value range can be customized in the Lab. By default, sliders are set to the mid-range position, but their initial Y value can also be adjusted in the Lab. You can change the color of their edges, background and level bar in the Lab. (See Style section)

2D Fader

2D sliders enable you to control up to three CCs and/or CVs with a single finger, offering intuitive X/Y/Z movement and visual feedback. You can adjust their value range and initial settings in the Lab, as well as customize the color of their edges, background, and level bar for a personalized look.

Ableton Live Controller

This Launchpad element strips down to the essential : launching Ableton clips, soloing and muting up to 10 tracks.

API Zone

The Erae API is a custom sysex library with messages enabling you to take full control of the Erae point detection and LEDs states.

‍

‍

Erae 2 is a MIDI Polyphonic Expression Controller (MPE), which is a relatively new standard for expressive electronic music performance. It enhances MIDI by allowing each note played to be controlled independently on its own MIDI channel. This enables expressive features such as pitch bends, vibrato, and dynamics for individual notes in a chord, rather than applying these effects uniformly to all notes.

‍

All pitched elements (such as keygrids, keyboards, and drum pads) can operate in MPE mode by enabling the MPE button either in the Erae Mapping section or the Lab’ Tune section.

‍

MPE in Ableton Live

First, make sure your Erae 2 is connected and Erae 2 (MIDI (MPE)) toggled on. 

‍

‍

Then, route your Erae 2 (MIDI(MPE)) in the “MIDI from” In/Out Section in Ableton Live. Enabling “Remote” will enable you to map control changes (CCs).

‍

MPE in Logic Pro

Make sure your Erae 2 is connected and Erae 2 (MIDI (MPE)) selected in the MIDI in Port section in Logic Pro. Also, make sure you are using a compatible MPE AU-instrument!

‍

 ‍

MPE in Cubase

Go in studio > studio setup. Once the window is open, clique on « add device » and select « note expression input device » In midi input, select « Erae 2 Midi (MPE), then select « note expression » in the inspector of your track

‍

Select the desired expressive dimensions or CCs, then click on "Parameter Details" to assign them.

‍

Finally, select in your midi inputs « Erae 2 Midi Input » in your track inspector and set the channels to « any ».

Let’s dive into Erae’s setting section, where you will  find how to save and load projects, adjust global settings such as the overall LED brightness, tempo, I/O routing and more. 

Save Project 

Click once to save your project. Note that it will be saved in the current project location, which can be specified in the Load Project parameter.

Load Project 

Single-click to cycle through the 8 available projects. Click on a selected project to load it. Use the undo button to return to the Settings menu.

In Erae 2, Program Change, Bank Select, MSB, and LSB are used to control and select sounds or patches on a MIDI-compatible device. Buttons and both footswitch A and footswitch B can send Program Change on both states ON (trigger) and OFF (release). You can also latch these two states. 

Some jargon about on/off states:

We call BankSel off, MSB off, LSB off and PC off, the Bank Select, MSB, and LSB and Program Change value corresponding to the off-state or release state of the button/footswitch pedal.
Similarly, we call BankSel on, MSB on, LSB on and PC on, the Bank Select, MSB, and LSB and Program Change value corresponding to the on-state or triggered state of the button/footswitch pedal. 

Here's what Bank Select, MSB and LSB mean:

Bank Select:

• MIDI allows for 128 program changes (0–127), but some devices offer more than 128 patches or sounds. To access these additional sounds, the Bank Select command is used to switch between different banks of sounds or presets.
• It’s essentially an extension of the Program Change command.

MSB (Most Significant Byte):

• The MSB is part of the Bank Select message and represents the higher-order byte (more significant digits) of the bank number.
• It defines the "coarse" part of the bank, which allows for broader selection across multiple banks.

LSB (Least Significant Byte):

• The LSB is the complementary part of the Bank Select message and represents the lower-order byte (less significant digits) of the bank number.
• It provides finer granularity within the bank selection process.

How They Work Together:

• To select a specific sound, you typically:some text
  1. Send a Bank Select MSB message.
  2. Optionally send a Bank Select LSB message.
  3. Send a Program Change (PC) message to choose the desired patch within the selected bank.

This three-step process ensures you can select from a much larger range of sounds than what a single Program Change message can handle alone. Keep in mind that buttons, footswitch A and footswitch B can handle MSB/LSB/PC for both ON/OFF states. 

Example:

If a synthesizer has multiple banks of 128 patches:

• BankSel off MSB 1, LSB 0, Program Change 10 might select patch 10 in bank 1 when a button or footswitch is released
• BankSel on MSB 2, LSB 3, Program Change 50 could select patch 50 in bank 2, sub-bank 3 when a button or footswitch is triggered

These messages are often managed automatically by software or hardware MIDI controllers, but understanding their structure is essential when programming MIDI manually.

‍

The Mapping settings are accessible both on the Erae and on the Lab. They provide access to MIDI parameters such as channel, pitch bend range, and Control Change (CC). These settings allow you to send CC messages to your DAW or synth corresponding to various touch dimensions: absolute X, absolute Y, pressure Z, relative X, and relative Y (all explained in detail). Additionally, it displays the channel number of the active element in the current layout.

‍

How to map a CC

Whether you set the CCs on the Lab or directly on the Erae, you’ll need to map them to your DAW or synth from the Erae. To do this, simply trigger the toggle button corresponding to the CC attribute you wish to map.

For example, if you want to map Pressure to a parameter in your DAW, first ensure your DAW is in mapping mode or learn mode. Then, on your Erae, press the MAP button, scroll down to Pressure, and toggle it on. This will send the CC value assigned to the Pressure CC, which is displayed just below.

If you modify the Pressure CC value, you’ll need to toggle Pressure off and then back on to apply the change. If Pressure is already toggled on but your DAW parameter hasn’t been mapped, simply toggle Pressure off and on again.

Out routing

Set the "out routing" of your element to your chosen MIDI output I/O
‍

• USB device out: On/Off
• MIDI Out A: On/Off
• MIDI Out B: On/Off
• USB Host out: On/Off

MPE
‍

Set your pitched element in MPE or not

On/Off

Channel

Set your element MIDI channel from 1 to 16, or Channel 1 (low) / Channel 16 (high) if MPE is toggled on

MIDI 1 →  [1;16]
MIDI MPE → (Channel 1, 16) - equivalent to Low and High registers

PB Range

Pitch bend range is set to 12 semitones by default when MPE is off and 48 semitones when it’s on

Pressure

On/Off - Pressure is Mapped to a CC to the pressure

X & Y Abs

X abs

Map a CC value to X abs - corresponds to the X-axis (horizontal) position in a cartesian frame of reference where (0) is at the left of the key and (127) on the right. You can set the Min/Max range in the Lab.

Y Abs

Map a CC value to Y abs - corresponds to the Y-axis (vertical) position in a cartesian frame of reference where (0) is at the bottom of the key and (127) at the top right hand corner. You can set the Min/Max range in the Lab.

‍

X & Y Rel

X Rel

Map a CC value to X Rel - corresponds to the relative displacement in the X-axis (horizontal) in a cartesian frame of reference where default value 63 is at the onset touch location. You can set the Initial Value in the Lab as well as the Min/Max range. 

Y Rel

Map a CC value to Y Rel - corresponds to the relative displacement in the Y-axis (vertical) position  in a cartesian frame of reference where default value 63 is at the onset touch location. You can set the Initial Value in the Lab as well as the Min/Max range. Within the Mapping settings, you can find MIDI parameters such as channel, Pitchbend range, Control Change (CC). The main purpose is to send your DAW or synth the control change (CC) corresponding to the different touch dimensions : abs X , abs Y , pressure Z , rel X and rel Y (all explained . It also displays the channel number from the active element on the current layout. 

Erae2 has a whopping 24 analog outputs for all your CV needs. Each of the 12 dual jack output can either be used directly or with a dual splitter.

‍

The voltage range of -5/+8V will cover all you need to take control of your modular rig : 1V/oct, triggers, unipolar and bipolar modulation, and more in the future!

The CV outputs are easily configurable via Erae lab, we will cover all settings for every element in this chapter. 

Overlapping routings issue: 🚩

Note that we did not restrict the use of outputs to just one element, meaning that one output can be used on 2 different layouts, which could create conflicts if for example you record a loop on one layout and play the other simultaneously. The Erae Lab will warn you when there are conflicts in the routing, but won’t prevent you from doing it !

‍

‍

Control Voltage attributes

The control change attributes in the Lab's TUNE section are listed at the bottom as following:

• Enabled [on/off]
  You can enable or disable CV in the selected element 
• Output [1-24]
  Corresponds to the physical CV output number where you want the CV attribute list to start (more on this in the  “Ordering of voices with physical outputs “ section)
• Num Voice
  Corresponds to the number of attributes (eg. gate, pitch, etc.) per note or voice.

‍

Let’s dive in the Num Voice attributes. For each note, you can set up to 8 attributes, listed as below.

Voice number principle

For each CV attribute active in the Lab/Tune/CV section, you need one physical CV output

If you want to play CV modulars with polyphony, you will need to use several notes we call voices. As seen above, each voice is comprised of 1 or several (up to 8) attributes (eg. gate, pitch, pressure, etc.). Each voice will require the same number of outputs required for the number of attributes you enable. For instance, if you enable 4 attributes (eg. gate, 1V/oct, velocity and pressure), you will require 4 outputs per voice. 

‍

Ordering of voices with physical outputs

The principle is simple: one voice requires x outputs (1 to 8). All available physical outputs will be grouped by the number of enabled attributes. Setting the voice number means repeating this set of enabled attributes several times. One set of attributes/outputs per voice, up to the desired (and available) number. 

Eg. With 24 outputs available, you can play up to 6 notes/voices (4x6=24).

Single mode (no splitter used)

The output attribute corresponds to the number where the physical outputs start. If you need two attributes for a button (eg. Gate & 1V / Oct) and have the Output attribute: 5, then it means CV data is streamed as follow. 5: Gate, 6: 1V / Oct

Dual mode (splitter used)

When using splitter cables, each physical CV output is effectively doubled. The same principles outlined earlier still apply, but the ordering is adjusted as follows.

‍

Keyboards, Key, Keygrids and Drumpads

• Enable : enable/disable CV output for the selected element
• Output : Select the first hardware output. Each enabled output of the following section will be assigned sequentially in the order they appear here.
• Num voice : Select number of voices for polyphony. Each voice will use the same amount of CV with every enabled parameter, so to know how many outputs you need, multiply the number of enabled CV outputs by the number of voices.
• Gate : Toggle 5V gate 
• 1 V/Oct : Toggle 1V/Octave
• CV Velocity : Toggle velocity. When enabled, you can select the voltage range  of the output.
• CV Pressure : Toggle pressure.  When enabled, you can select the voltage range  of the output.
• CV X abs : Toggle X absolute modulation, or absolute horizontal modulation. On each key, the lowest value is the left-most position, and the highest value is the right-most position. When enabled, you can select the voltage range of the output.
• CV Y abs : Toggle Y absolute modulation, or absolute vertical modulation On each key, the lowest value is the bottom position, and the highest value is the top position. When enabled, you can select the voltage range of the output.
• CV X rel : Toggle X relative modulation, or relative horizontal modulation. On each key, the lowest value is the left-most position, and the highest value is the right-most position. You can set an initial value and a range. The initial value is set on the initial strike position of your finger.
• CV Y rel : Toggle Y relative modulation, or relative vertical modulation. On each key, the lowest value is the bottom position, and the highest value is the top position. You can set an initial value and a range. The initial value is set on the initial strike position of your finger.

CV Calibration

Instructions:

●     Unplug all CV TRS jacks andFootswitch pedal

●     Start Erae2 with external powersupply

●     Go to [SETTINGS] menu and selectRun CV calibration

The calibration process will take about 5 to10 minutes and the Erae2 will reboot automatically after the calibration.

Once the calibration is complete, it ispossible to also adjust the calibration gain (scaling factor) manually:

●     Go to [SETTINGS] menu

●     Change the CV gain (cent / octave)

‍

The two rightmost jack outputs (11 and 12) can be configured as expression or switch pedal input. You can enable and configure it in the global settings. The Erae can handle both footswitch (On/Off) and expression (potentiometer) pedal with continuous output.

For the footswitch pedal (with On/Off actions), you should configure the pedal as a button or a note, you have the same configuration options as a button element.

For the expression pedal, the continuous value can be freely assigned to any MIDI CC output.

‍

The Lab is your space to customize your Erae 2 and handle your projects. From one single view, you can access all your projects stored in the computer and in Erae 2’s memory, create layouts from scratch or from a previously created one, and tune the elements. Each section is explained in the Learn panel based on where your mouse is hovering. However, here’s a zone-by-zone breakdown of what you can do to customize your product.

When you open the Lab, a blank layout appears, ready for you to begin composing in the Compose tab. To design your layout, simply drag and drop elements from the Compose pane into the central workspace. Each project can include up to 8 layouts, which can be saved together as an .erproj file. Additionally, individual layouts can be exported as .emk files, allowing you to easily manage and organize them across various projects.

Loading projects from your computer

To load an existing project, click the open button. A pop-up window will appear, allowing you to select a file from your computer. Once loaded, the project's 8 layouts will be imported, with the first layout displayed by default.

Loading and saving projects from your Erae

Use the Settings button and LCD menu to load one of your 8 available projects. Similarly, save a project to one of the 8 slots via the Settings button and LCD menu. Be sure to save any modifications made to the current project (e.g., changes to scales on layouts, MPE settings, or added looper patterns) to retain them after a reboot.

Push projects from the Lab to the Erae

To organize projects within the Erae 2, you need to assign them to the correct slots (e.g., project_1, project_2, ... project_8). For example, if you've created a project from scratch in the Lab and want to save it to slot 2, first load project 2 on the Erae through its settings. Then, in the Lab, click the "To the Erae" button to transfer your project.

Load projects from the Erae to the Lab

To load a project onto the Erae, go to Settings → Load, then press the "From the Erae" button in the Lab. The entire project will load, with the first layout displayed by default.

‍

Each layout element can be customized in the Lab with options like MIDI channel settings, velocity curves, control change values, colors, sizes, and more. The Tune feature provides another way to adjust element settings, offering flexibility to work even when you're away from your Erae. For example, scales can be pre-configured in the Lab but are also editable directly on the Erae 2 with a single click. Similarly, control changes can be set in the Lab or mapped directly from the pad on the Erae. Keep in mind that scale changes apply only to the currently displayed layout, and if multiple elements are present in a layout, the change will affect the most recently touched element.

Tune Keyboards and Keygrids

Keygrids draw inspiration from string instruments and can be made isomorphic by setting any scale to chromatic. To enable or disable MPE mode on Keygrid or Keyboard elements, toggle the MPE selector under the Tune tab.

In both MIDI 1.0 and MPE modes, the Tune tab focuses on two main aspects: Note and Expressivity attributes.

• Note attributes define settings like scales, pitch bend ranges, and MIDI channels.
• Expressivity attributes control gesture-based parameters such as finger X-Z positions, X-Y relative movements, and advanced pressure options.

This setup ensures a high level of customization for expressive and versatile performance.

Use the Style panel on the right side of the Lab to personalize the appearance of your elements. Each element has an intuitive customization process, enabling you to design a controller that truly stands out—whether you're using it at home or performing on stage. We’re excited to see your creations!
