so if you are asking for help that would be the helpful information to give, not a picture of a mixer and sequence window without any routing information
so I take it you have recorded these waveforms since you post them?
but what soundcard? which asio driver? do you use the stereo out or the control room?
Hi - you were right - the person who had changed my hardware setup had changed the asio driver. Now restored to its former glory. Thank you for your help!
Best
