Mapper
The Mapper links Cellular interface elements at the position of the currently selected target button to the most recently modified MIDI controller — pressed key, button, or moved slider.

The Mapper interface consists of two types of purple elements: for selecting targets of program changes and continuous controllers.
Program change target selection buttons
Continuous controller target selection button
Clicking a target selection button assigns a position for mapping to a MIDI controller. Clicking another target selection button first cancels the previous selection, then selects a new position.

The tempo slider area displays the channel and controller numbers mapped to the selected target or "…" if no mapping exists.
For example, channel 15 and controller 127
