Cannot Hear Electric Guitar

[ahendriks]

Hi. Last week I plugged in an electric guitar to the front end of my Mackie ONYX 400F. I could hear the guitar sound through my monitors while practicing. Tried it this week and no sound. It records the sound fine, but I cannot hear it until playback of the recording. Any ideas on what I'm missing?

EDIT: Figured it out. I think my T4 was set up for 'end-to-end' and in T5 it's 'live input monitoring', which I didn't have turned on.
