I really want to know how I can make a sound. I'm using FL Studio and I hope I can make this sound one time. The sound it is about:

Please search on YouTube:

Mij Niet Eens Gezien | 00:46 - 01:07 |
Know No Better | 01:05 - 01:20 |
One Night Stand | 01:13 - 01:26 |

It's like the sound of a mixed voice, or some type of flute (I really don't know what it sounds like. So does anybody know how I can make this sound? It would help me a lot because it would finish my song.

I hope someone can help me,<

Thank you!
