Jon Johnson 208 Report post Posted April 29, 2017 The housing of the C15 synthesizer consists of two detachable parts: the base unit and the panel unit. The compact base unit contains all of the instrument's processor and audio components; it can be used without the panel unit in "play only" situations. The panel unit is an haptic user interface, mainly for sound design, but it can also be useful for controlling presets and morphing for a complex performance.
