Automating KLANG with Reaper
Reaper’s built-in OSC functionality allows to write and read automation data for KLANG’s level as well as horizontal and vertical panning, by simply using Reaper and KLANG:app. Both programs can run on the same computer if you wish. Follow the next steps to set this up.
