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)
