Hi. Could you give some more detail please, so we can verify it?

Is this a notated RealTrack? Or a MIDI track you entered?

Is what you hear shorter than what we see, so it's shorter than a dotted half note?

If it's a RealTrack, what style or RealTrack is this bass part? Does the same song do the same thing if you change the RealTrack or style?

If it's MIDI, go into the MIDI step editor and look for a rest.

The more you can tell us, the better.
