Can't get trial software to work

Ive installed the trial software and selected the input as my Focusrite USB (My Scarlett is attached to the computer and works perfectly in Ableton). I can hear my guitar through the headphones, but i haven’t got the piano sound. Am i missing something obvious?
The online guide says i need to select the output (as well as the input), but i cant see how to do this. Im assuming the Scarlett is my output too, but maybe im wrong. Can anyone help?

if ‘direct monitor’ is on, you’d hear the guitar regardless of if mg2 is running.

do you see any activity on the mg2 screen? next to the volume knobs is an indicator showing if mg2 is producing sound.

some more details would be helpful (mac/win?, screencap of your interface setup).
