I hate reverb!! Don't get me wrong, I love the effect, I just hate dealing with it. Nothing worse than a bad reverb or the misuse of it. Still a few suggestions tho. Most of the time you want to bus your source signal to a reverb aux track. Much easier to blend and control it if its on a seperate track. Always listen to your reverb with the the mix with the source track muted. It's much easier to set the proper level, decay, pre-delay,length, eq etc without the source track. It's always a good idea to eq your reverb the way you want it with a seperate eq. If you are trying to tempo sync your reverb and do not have that option in your reverb, divide 60.000 by your beats per minute. That will give you miliseconds. Or divide BPM/60 and that will give you seconds.
you can also mess with panning your send the same as your track.
