Thanks, it was exactly that. For some reason I thought you could map every OB parameter to the Rytm, but as it turns out its 127 parameter max (makes sense).
Now I have the drum rack with scene and performance pads always mapped as well as the fx stuff (apart from lfo - why?) thanks to the patrik stuff, awesome.
Whenever I want to write and automation, I map the parameter from the Rytm and write it like that.
Whenever I want to record, switch on the multi output from the OB control panel. Works great!
Now I'll add the mute functionality and I'm done!
