There are multiple ways to interact with the C15, each consisting of a different organisation and optimized layout of the information it represents, depending on the interface you are using. However, the basic structure and handling options remain comparable, as each form of interaction follows the same underlying principle.
This chapter covers these general concepts, terms and keywords in detail, and explains the various means of interaction with the User Interface and User Interface, along with the modulation mechanism and presets.
Overall, three interfaces are available:
The Unit provides access to all performance-related items ( Sources, ). It can also be used to edit parameters and navigate presets and banks. Navigation of parameters may be provided in future upgrades to the system.
The Unit can be used to select and edit parameters, modulation controls and system settings. Presets, banks and the undo history can all be navigated and managed here. In short, all the C15's data can be controlled with the Panel Unit.
Four Panels, are provided, each consisting of 24 Selection Buttons. Most of the parameters can be accessed this way.
The User Interface also provides full access to all parameters, modulation controls and system settings. However, it also offers more extensive helper features and settings, such as access to the C15 Documentation.

In earlier versions, the C15 only operated on its physical key range of 61 keys (C1 ... C6). The Note Shift was applied as a tuning, whereas Split Point and Fade From or Range parameters were bound to the physical key range, effectively ignoring the Note Shift.
Polyphonic Key Pan in the Output Mixer was also bound to the physical key range, also effectively ignoring the Note Shift.
With this static behavior of key ranges on polyphonic Part association, fade level and panning, it became apparent that there are limitations.
In this version, a virtual key range of 128 keys (C-2 ... G8) was added. The physical key range of 61 keys is now projected onto the virtual key range, depending on the Note Shift (which is now a real key shift and not a tuning anymore).
Extreme Note Shift may exceed the virtual key range for certain keys, in which case no note is produced.
Split Point and Fade From or Range parameters now operate within the virtual key range and the Note Shift can be used to transpose into or out of parts. The parameters still can only be set within the physical key range (C1 ... C6) - which will be addressed by a future update.
Polyphonic Key Pan in the Output Mixer now also operates within the virtual key range and the Note Shift can be used to transpose into or out of more extreme panning. At 100%, the panning starts to clip at the physical key range’s edges (C1 ... C6), at 47.24 % the panning covers the whole virtual key range (C-2 ... G8).
Each Interface allows you to interact with a number of elements (most of which are contained in presets). We explain these items and their features in general terms in this chapter (the individual interfaces are explained in full detail in chapter User Interfaces).
