I'm using the unit as a USB interface as well, and for some reason both ableton and youtube videos can't be played at the same time. This is something I do often with my previous Focusrite, I like to play a Jam track in Youtube and play keyboard on my midi at the same time. Any tips?
ok resolved. Both Ableton and computer need to be set to the same sample rate and bit depth. 48000 in my case. 24 bit
