At first, when i went to add a new instrument id click one and it wouldnt let me preview it. when i hit the keys on my controller there was no sound. So i went to audio connections and connected the monitor in the control room tab. When i did that it got my instrument preview working, but now i cant hear my metronome. It seems to only let me pick one or the other. how can i make it to where i can hear the metronome and also hear my instruments before i add them to my project?
