Here is a music censor bleep http://soundbible.com/1013-Music-Censor.html

But it is really just a synth sine wave. You could find a similar sound patch on almost any keyboard and play it holding the key down as long as you need it. Just bring up the Synth bank on whatever keyboard you are using and you should be able to find a sound that is very close. There really is no need to have to trigger a sample of such a basic sound.
