**Buttons 1-4** | Buttons 1 to 4 are contextual to the current screen. **Short Click** : They allow you to switch tabs or pages on the current screen, or perform a specific action when a modal window is displayed. **Long Click** : Opens the parameter modulation assignment located above on the screen. |
**360° Rotary Potentiometers 1-4** | Potentiometers 1 to 4 are contextual to the parameters displayed on the screen. There are up to 4 parameters presented simultaneously on the screen, each potentiometer controls the parameter located above it on the screen. |
**Digital Encoder** | The encoder is contextual to the current screen. It allows you to navigate through menus, different instruments, or scroll through various wavetables or samples. **Short Click**: Confirms a selection on the screen. |
**Exit / Alt Button** | **Short Click**: "EXIT" Button: Returns to the previous page. **Long Click: "ALT" Button**: Accesses alternative functionalities, generally allows access to additional tabs in the modules. **Long Click + Potentiometer 1-4**: Resets the parameter above the potentiometer to its default value. **Short click + encoder click:** preview the current instrument; the note lasts as long as the encoder is held. **Long click + turn encoder**: opens a shortcut menu. |
**Audio Outputs 1-4** | Audio outputs 1-4 are AC-Coupled, with a voltage range of -7.5V to 7.5V. |
**CV Inputs A-F** | CV inputs A-F operate within a voltage range of -5V to 5V. These inputs can be used for pitch control (standard 1V/oct) or modulation. Assignments are made in the software. |
**Gate Inputs 1-4** | Gate inputs 1-4 operate within a voltage range of 0 to 40V. The trigger threshold is approximately 0.7V. |
**Entrées CV G-L** | CV inputs G-L operate within a voltage range of -5V to 5V. These inputs can be used for pitch control (standard 1V/oct) or modulation. Assignments are made in the software. |
**Entrées Gate 5-6** | Gate inputs 5-6 operate within a voltage range of 0 to 40V. The trigger threshold is approximately 0.7V. |
**MIDI In** | Midi input is compatible with midi to jack 3.5 adapter (format TRS A or TRS B) |
**Power** | Standard eurorack power -12V / GND / +12V , Red stripe of the ribbon is on the left |
**MicroUSB** | Micro USB socket, to connect to a computer, used to update the firmware |
**Extension** | Extension port, used to plug the CV/Gate & Midi extension
Warning ! The ribbon cable must be plugged in the right direction. There is a "RED" inscription on the PCB which indicates where the red stripe of the ribbon should be. |
