The C15's architecture was designed to offer quick access to all items and aspects, with one central area representing the current focus. This main principle (of focussing on one item at a time for editing) affects each interaction on any available user interface. As mentioned, the current focus will be shared with all involved devices.
Panels provide Selection Buttons. The corresponding LED (left of the button) lights up to indicate the current focus.
Multiple parameters can be selected with a single Selection Buttons (indicated by circles below the LED).
The Selection Buttons or Button 4 allows you to cycle through the stack.
The Button provides access to the few parameter groups that are not directly accessible on the Parameter Panels.
Button 4 redirects to the Master group, Button 3 to the Unison and Mono groups. In Split and Layer Sounds, Button 2 redirects to the Part group, and Button 1 is available in many screens in order to change the Part in focus.
The Controls are shown as a distinct group. Pressing a Selection Button twice redirects to the Sources.
The Unit Display provides a corresponding screen for the selected item. The buttons of the Panel give access to all aspects of the items.
All parameters are shown in the main area and can be selected by clicking on them.
In Split and Layer Sounds there is a colored frame around the main area including an indicator for the selected Part.
A touch/click on the indicator opens the parameters of the other Part. (The User Interface has its own Part focus and will not reflect selections in the User Interface, unless it is deliberately enabled in the Menu.)
The background of an element highlights to indicate that it has been selected. Use the mouse wheel or pinch gestures on the main area background to zoom into the provided map.
A double click on a Group header zooms into the group. Different details emerge depending on the zoom level. High priority parameters are always visible.
Controls and Sources appear as separate groups in the main area, providing all related aspects.
The expandable tab area shows all item-related aspects. Parameters can be edited in the Tab.
Chapters Parameters to Presets detail selected parameter- or preset-related items. Further (menu-related) items and access to them will be explained in chapters Sound Manipulation to Graphical UI Functionality.
