Step One ( very Important ) - make a backup of the madmapper file.
Step Two - unlock the presets buy clicking on the lock icon on the preset panel
Step Three - click on the first preset, that will display the output from M8 then go to source tab and click on the QC output and just as a precaution save the file.
Step Four - go back to the preset panel now select the next preset and repeat the process of going to the output tab and selecting the output.
Step Five - once you have changed all outputs go back to preset panel and enable the lock again so you don't accidentally change it again.
If all works well awesome if not at least you have a backup
