This is what I know so far of how to connect to Mix Meister (it's annoying but once you get through this part you can use basic controls)

Tools > Options... then go to Midi tab

Set Harware Control

TouchOSC Bride

Midi Clock Output

TouchOSC Bridge

Control Template

Custom

Then you have to basically go into the Customize and click on each thing on the list of Midi Configuration

Once you click through each, click learn and hit the touchosc button or slider.

It has options from strip 1-8 but the controller I made either has 4 or 6 strips so ignore the extras
