It sounds like you are having some sort of problem, but it isn't clear what the problem is exactly. Please use the Support forum to ask for help in using MsueScore. When you do, please attach the specific score you are having problems with and give precise step by step instructions to reproduce the problem, so we can understand what you are talking about and advise you on how to solve the problem you are having.
Maybe you are referring to the reverb that is present by default? You can change the effects in View / Synthesizer.
