Whistle Sound

[eamusik2008]

Hello everybody. I hope you are all having fun with music and are in great health. I had a question. Does anybody know how to create a good sounding whistle using only the factory sounds. I have tried doing so using a sine wave, however, I cannot get the right effects or settings to make it sound real. Like you know the harmonica sound on the fantom x, it has amazing velocity controls and has that wild west feeling. It would be great to have something like this. If anybody is willing to help I would greatly appreciate it and would be a benefit of everybody here.
Thanks.
