killihu has released Mapper-Ki, a M4L plugin that allows you to morph Ableton Live's mapped controls and external MIDI hardware controls in various ways. It can be used for live performance and in the studio.
Mapper-Ki has a total of 16 presets to store different configurations. Control values can be interpolated when switching presets, either linearly or alternately.
Multiple Mapper-Ki can be controlled at the same time, making it possible to control as many Live parameters as desired.
It has randomization options, allowing you to exclude those controls and presets that you do not want to randomize.
The included Mapper-Ki Remote plugin allows you to control Mapper-Ki with an external MIDI controller. It has a specific mode designed for Launchpad controllers.
