Okay, this is the exact opposite to what I expected 
I thought that Konnekt would be behind MR in this setting… Now I agree with you, there is really something with the MR. Perhaps you have the internal effects active on MR’s own inputs? You can try this experiment: please, leave MR as the master recording interface, go to the MR Control Panel and change the internal effects setting. Place the effects on the ADAT inputs, rather than on the analogue inputs. Will this adjustment affect the latency?
