Single Mapper extends mapping control in Ableton Live, whether used individually or alongside an effects rack, by adding custom curves to each mapping. It also displays the current value of the mapped parameters, allowing for precise adjustments at any point along the curve.

It can be controlled from a Macro Control on an effects rack, adding the custom curve feature to the Macro Control. In addition to the individual curve editor for each mapping, it also features a global curve editor that affects all mappings on the device.
