The left side of Osmose is built around an interactive graphic interface that provides access to all onboard parameters. The navigation works via five buttons and six clickable encoders whose functions change depending on the current screen.

1. MODE button / SHIFT (m) - opens the Main Menu (mode selection screen) when in Sound Engine Mode or External MIDI mode. In DAW Control mode, pressing it shows or hides the Transport Panel. Holding it as SHIFT button gives access to secondary functions.
    
2. MENU buttons -  access one of the four menus of a mode, or work as transport controls when Transport panel is open in DAW Control Mode.
    
3. Knob A (TAB Selector) - scrolls through the tabs of a menu. When in Sensitivity or Playing menu, pressing the Tab Selector freezes the settings of the menu to retain them even when switching presets.
    
4. Knob B (PARAMETER Selector) - scrolls through parameters inside a tab. When in Playing menu, pressing the Parameter Selector starts or pauses the Arpeggiator or switches Pressure Glide on and off.
    
5. VALUE Encoders 1-4 - change the value of the parameter displayed above or scroll through a list of options. 

The icons displayed next to each encoder indicate the available actions for that knob.

horizontal arrows: turn to scroll through tabs or parameter lists, see ‘navigation principles’ below.

vertical arrows: turn to change the parameter shown above. With colored dot: press to select or toggle. 

colored dot with special symbol: press to trigger a special function.
