So I have proper configured and customized my DM3200 with Samplitude, it's now the time for Reaper! Mackie Control seems very well implanted in Reaper with Klinke's MCU extension but I'm facing a problem. The basics control works fine but when I want customise it in "Actions List" via midi learn, Reaper doesn't reconise any controllers (neither faders, nor mute etc... nada) of the DM3200 remote in Mackie control mode when I want to add or change a controller for a function. I don't know what I missed here. Does anyone have success with configuring reaper?
