If you go to Options | Preferences, on the left hand side of the window you'll see there are different settings for the lead-in. You can change the type of instrument, the pattern, and volume of the lead-in.

RealBand is a Windows only application. So the above suggestion by Bob for further editing in RealBand would alternatively work in other DAWs that are compatible for Mac, like Garageband.
