I am trying to record an electric guitar with a DI box and I can't hear the metronome unless I undo the solo button. If I undo the solo button I can't hear the guitar. Any suggestions? Thanks
 

Hmmm... those are both odd symptoms. Soloing a track should not interfere with metronome, and it shouldn't be necessary to solo a track to hear it, unless you're saying the level is so low that it's drowned out by the rest of the mix...? Routing of the meteronome shouldn't matter, either, but is it going through a Metronome bus to Master or direct to Master or...? Is the problem specific to this project, or you're new to SONAR/CbB, and haven't tried this previously?

Thanks, I am totally new at this and a drummer to boot. I never dealt with electronic stuff hardly at all in all my 30 years of playing. I am a high school band teacher and have started a rock band class. I bought all this stuff because it is obviously important for the kids to hear themselves. Just so you know where I'm coming from. 
 
New question, I am back at this. Now I am trying to overdub a bass part to a recording. My X32 Producer is showing a signal as is cakewalk but the bass sound is not audible through my monitors. Is there something I am missing?

Ha. Just happened to wake up early and see this right away. To monitor live audio input through SONAR you have to enable the Input Echo button on the track. Looks like )))
 
So I guess you got the metronome problem figured out at some point. do you remember what the problem was?
 
"drummer to boot" 

drummers make better engineers

Monitoring is best done directly at your audio interface. If you do not have an audio interface you are missing the most important component for recording audio.
